Direct determination of the spin structure of Nd2Ir2O7 by means of neutron diffraction

H. Guo, C. Ritter, and A. C. Komarek

Phys. Rev. B 94, 161102(R) (2016) - Published 3 October, 2016

Among others, pyrochlore iridates with strong spin-orbit coupling have received attention recently due to the prediction of Weyl semimetal states in these materials. Despite tremendous efforts, there exists no direct measurement of the spin structure at the iridium site by means of neutron diffraction. This might be caused by the small ordered Ir moment and also by the neutron absorbing properties of the Ir ions. Up to now, only basic indirect evidence for the spin structure at the iridium site exists. From the observation here of the full magnetic structure of Nd2Ir2O7 via neutron diffraction experiments, the authors obtain direct insight into unknown aspects of the physics of the iridium ions in pyrochlore iridates.

Helicity-dependent photocurrent in a Bi2Se3 thin film probed by terahertz emission spectroscopy

Sun Young Hamh, Soon-Hee Park, Sahng-Kyoon Jerng, Jae Ho Jeon, Seung-Hyun Chun, and Jong Seok Lee

Phys. Rev. B 94, 161405(R) (2016) - Published 20 October, 2016

Topological insulators have been attracting much attention as potential candidates for spintronic applications. Spin-momentum-locked surface states can lead to spin current naturally accompanied by electric charge current. As a way to control the current, circularly polarized photon injection has been widely used as the photon can excite spin-polarized carriers selectively depending on the photon’s helicity. Here, the authors investigate the helicity-dependent photocarrier dynamics in an unbiased Bi2Se3 thin film by monitoring the terahertz pulse emitted from the sample after illumination by femtosecond laser pulses. Although all the measurements were performed on an unbiased sample with no electrical contacts, the authors observe three-fold periodic helicity-dependent terahertz emission, and attribute such circular anisotropy in the photocurrent to the circular photon drag effect, namely linear and angular momentum transfer from photons to photocarriers.

Cubic scaling GW: Towards fast quasiparticle calculations

Peitao Liu, Merzuk Kaltak, Jiří Klimeš, and Georg Kresse

Phys. Rev. B 94, 165109 (2016) - Published 5 October, 2016

The GW method is the standard method for predicting quasiparticle energies as measured in experimental photoemission spectroscopy. Until recently, routine GW calculations have been restricted to fairly small systems and few k points for sampling the Brillouin zone, since the computational demand usually scales quartic with the number of atoms and quadratic with the number of k points. The original work of Lars Hedin suggests that one can do better by calculating the self-energy as Σ(1,2)=iG(1,2)W(1,2) – the equation that coined the phrase ”GW”. Here, G is the one-particle Green’s function and W the screened interaction between the electrons. Using this relation directly in computations brings the scaling down to linear in the number of k points and cubic in the number of atoms. Although this approach has been used in the past by others, in this work its full potential is unveiled by implementing it in a massively parallel code and adopting it to the projector augmented wave method. This makes GW calculations as convenient as calculations based on local density functionals and allows for calculations for hundred atoms in few hours.

Coupled wire model of symmetric Majorana surfaces of topological superconductors

Sharmistha Sahoo, Zhao Zhang, and Jeffrey C. Y. Teo

Phys. Rev. B 94, 165142 (2016) - Published 19 October, 2016

Classification of symmetry-protected topological phases such as the topological superconductor (TSC) is well known in the free fermion picture. Recently, it was observed that including many-body interactions that preserves symmetry gives rise to novel surface phases and breaks down the classification scheme. A complete understanding of the microscopic theory for such phases is missing. This paper is an attempt to understand the interaction that gives rise to these phases in the case of the three-dimensional TSC. The authors build a coupled wire model Hamiltonian for the gapless surface and show that the addition of a time-reversal symmetric two-body interaction, constructed in this paper, opens an energy gap in the spectrum. They also show this gapped surface phase is topologically nontrivial and is classified differently compared to the noninteracting case.

Quasiparticle interference from different impurities on the surface of pyrochlore iridates: Signatures of the Weyl phase

F. Lambert, A. P. Schnyder, R. Moessner, and I. Eremin

Phys. Rev. B 94, 165146 (2016) - Published 19 October, 2016

Weyl semimetals make up a novel three-dimensional topological phase of matter. Among their most fascinating properties is the existence of a very peculiar type of surface bound state. Contrary to common topological materials, the surface Fermi surface of a Weyl system consists of disconnected arcs – the so-called Fermi arcs – instead of a closed surface. These Fermi arcs connect the projected position of band crossings in their bulk band structure. The Weyl phase typically arises from a symmetry-protected topological insulator upon spontaneously breaking one of the protecting symmetries. In the case of the pyrochlores, the magnetic momenta inside the constituting Ir tetrahedra break time-reversal symmetry, so the pyrochlores are considered magnetic Weyl semimetals. Here, the authors show theoretically that the nontrivial spin polarization of the surface Fermi arcs of a magnetic Weyl semimetal provide characteristic feature observable via spin-resolved scanning tunneling microscopy (STM). They analyze the Fourier transform (FT) of Friedel oscillations in the local density of states occurring due to scattering by localized magnetic and nonmagnetic impurities. They note that the FT features inherit traces of the disconnected nature of the Fermi surface and the spin rotation happening on the Fermi arcs.

Revealing the role of electrons and phonons in the ultrafast recovery of charge density wave correlations in 1TTiSe2

Electrons in low-dimensional materials sometimes reorganize themselves with a new translational symmetry, which gives rise to an energetically more favorable ground state. This phenomenon, called a charge density wave (CDW) phase, is often the result of the coupling of electrons to phonons. In the quasi-two-dimensional material TiSe2, the CDW occurring at low temperature is unusual, since it appears to be driven by strong electron-hole correlations, which in turn couple to phonons. In this work, the authors use time- and angle-resolved photoemission spectroscopy to investigate the peculiar nature of the CDW phase in TiSe2.Depending on the temperature at which measurements are performed, they observe that the response of the material is either strongly coupled to the lattice or dominated by its electronic degrees of freedom. This selective response is enhanced by tuning the pump pulse wavelength to specific optical resonances. They conclude that their measurements do indeed confirm a combined scenario, for which both the electron-hole correlations and the coupling to phonons are essential to the origin of the CDW phase in TiSe2.

Magnetic ratchet effect in bilayer graphene

Narjes Kheirabadi, Edward McCann, and Vladimir I. Fal'ko

Phys. Rev. B 94, 165404 (2016) - Published 6 October, 2016

The magnetic ratchet effect is optical rectification in two-dimensional systems – such as bilayer graphene – whereby a steady in-plane magnetic field and the alternating electric field of a laser produce a dc electric current. It occurs in systems with broken inversion symmetry due, say, to an inhomogeneous distribution of impurities, leading to increased electronic scattering on the upper layer of the bilayer. For a given direction of electric field, electrons are driven downwards by the Lorentz force towards the lower layer where scattering is low whereas, when the electric field switches direction, electrons are driven towards the upper layer where scattering is high. Such asymmetry in scattering leads to a nonzero dc current. By deriving linear-in-magnetic-field terms in the low-energy electronic Hamiltonian, the authors predict a very large ratchet effect in bilayer graphene. They compare symmetry breaking due to impurities with interlayer asymmetry due to an external gate, the latter allowing for a tuneable magnetic ratchet.

Photoexcitation of electron wave packets in quantum spin Hall edge states: Effects of chiral anomaly from a localized electric pulse

Fabrizio Dolcini, Rita Claudia Iotti, Arianna Montorsi, and Fausto Rossi

Phys. Rev. B 94, 165412 (2016) - Published 13 October, 2016

In the helical edge states of a quantum spin Hall (QSH) bar, the phenomenon of electron photoexcitation is quite different from systems commonly used in optoelectronics. The vertical electric dipole transitions typically occurring between valence and conduction bands of conventional semiconductor-based devices are forbidden in QSH edge states due to a selection rule. Also, electrons in QSH edge states are described by a massless Dirac fermion theory rather than the conventional Schrödinger-like parabolic band, so their response to an electromagnetic field is intrinsically affected by a peculiar effect known as the chiral anomaly. Here, the authors analyze this problem in the mesoscopic regime. They show that, when a spatially localized electric pulse is applied at the edge of a QSH system, helical electron wave packets can be photoexcited by purely intrabranch electrical transitions, without invoking the magnetic Zeeman coupling or transitions to bulk states. At the end of the pulse, the wave packets counter propagate with opposite spin orientations, keeping their space profile unaltered. Notably, the authors find that the space profile of the photoexcited electron wave packets is independent of the temperature and chemical potential of the initial equilibrium state. Instead, the profile depends purely on the applied electric pulse, in a linear manner, as a signature of the chiral anomaly. Then authors discuss how the wave packet profile can be tailored by the electric pulse parameters, for both low and finite frequencies.

Spin excitations in an all-organic double quantum dot molecule

Phys. Rev. B 94, 165414 (2016) - Published 14 October, 2016

Double quantum dots play an important role in the field of semiconductor and carbon nanotube quantum dots. They have resulted in, for example, correlated electron physics beyond the single spin-1/2 Kondo system and the realization of qubits for quantum computation. Using organic molecules to create a double quantum dot can be beneficial due to the larger energy scales present as compared to its more extended counterparts. Furthermore, they open up the possibility to investigate interactions between spins and perform coherent experiments on electrons in organic molecules. In this article, the authors experimentally investigate charge transport through a three-terminal single-molecule junction. The data shows features in transport that arise from the broken conjugation in dihydro-anthracene, which localizes π electrons and creates a set of nearly degenerate orbitals. The ferromagnetic and antiferromagnetic interactions are of the same order of magnitude, so that the singlet and triplet states are close in energy. These findings thus demonstrate a double quantum dot programmed in a single molecule due to its broken conjugation. This research is a starting point for further experiments, whereby with chemical means the interaction between the two dots can be lowered to observe Pauli spin-blockade and investigate spin coherent effects in single molecules.

Classification of symmetry-protected topological phases such as the topological superconductor (TSC) is well known in the free fermion picture. Recently, it was observed that including many-body interactions that preserves symmetry gives rise to novel surface phases and breaks down the classification scheme. A complete understanding of the microscopic theory for such phases is missing. This paper is an attempt to understand the interaction that gives rise to these phases in the case of the three-dimensional TSC. The authors build a coupled wire model Hamiltonian for the gapless surface and show that the addition of a time-reversal symmetric two-body interaction, constructed in this paper, opens an energy gap in the spectrum. They also show this gapped surface phase is topologically nontrivial and is classified differently compared to the noninteracting case.

Weyl semimetals make up a novel three-dimensional topological phase of matter. Among their most fascinating properties is the existence of a very peculiar type of surface bound state. Contrary to common topological materials, the surface Fermi surface of a Weyl system consists of disconnected arcs – the so-called Fermi arcs – instead of a closed surface. These Fermi arcs connect the projected position of band crossings in their bulk band structure. The Weyl phase typically arises from a symmetry-protected topological insulator upon spontaneously breaking one of the protecting symmetries. In the case of the pyrochlores, the magnetic momenta inside the constituting Ir tetrahedra break time-reversal symmetry, so the pyrochlores are considered magnetic Weyl semimetals. Here, the authors show theoretically that the nontrivial spin polarization of the surface Fermi arcs of a magnetic Weyl semimetal provide characteristic feature observable via spin-resolved scanning tunneling microscopy (STM). They analyze the Fourier transform (FT) of Friedel oscillations in the local density of states occurring due to scattering by localized magnetic and nonmagnetic impurities. They note that the FT features inherit traces of the disconnected nature of the Fermi surface and the spin rotation happening on the Fermi arcs.

Electrons in low-dimensional materials sometimes reorganize themselves with a new translational symmetry, which gives rise to an energetically more favorable ground state. This phenomenon, called a charge density wave (CDW) phase, is often the result of the coupling of electrons to phonons. In the quasi-two-dimensional material TiSe2, the CDW occurring at low temperature is unusual, since it appears to be driven by strong electron-hole correlations, which in turn couple to phonons. In this work, the authors use time- and angle-resolved photoemission spectroscopy to investigate the peculiar nature of the CDW phase in TiSe2.Depending on the temperature at which measurements are performed, they observe that the response of the material is either strongly coupled to the lattice or dominated by its electronic degrees of freedom. This selective response is enhanced by tuning the pump pulse wavelength to specific optical resonances. They conclude that their measurements do indeed confirm a combined scenario, for which both the electron-hole correlations and the coupling to phonons are essential to the origin of the CDW phase in TiSe2.

Magnetic ratchet effect in bilayer graphene

Phys. Rev. B 94, 165404 (2016) - Published 6 October, 2016

The magnetic ratchet effect is optical rectification in two-dimensional systems – such as bilayer graphene – whereby a steady in-plane magnetic field and the alternating electric field of a laser produce a dc electric current. It occurs in systems with broken inversion symmetry due, say, to an inhomogeneous distribution of impurities, leading to increased electronic scattering on the upper layer of the bilayer. For a given direction of electric field, electrons are driven downwards by the Lorentz force towards the lower layer where scattering is low whereas, when the electric field switches direction, electrons are driven towards the upper layer where scattering is high. Such asymmetry in scattering leads to a nonzero dc current. By deriving linear-in-magnetic-field terms in the low-energy electronic Hamiltonian, the authors predict a very large ratchet effect in bilayer graphene. They compare symmetry breaking due to impurities with interlayer asymmetry due to an external gate, the latter allowing for a tuneable magnetic ratchet.

Photoexcitation of electron wave packets in quantum spin Hall edge states: Effects of chiral anomaly from a localized electric pulse

Phys. Rev. B 94, 165412 (2016) - Published 13 October, 2016

In the helical edge states of a quantum spin Hall (QSH) bar, the phenomenon of electron photoexcitation is quite different from systems commonly used in optoelectronics. The vertical electric dipole transitions typically occurring between valence and conduction bands of conventional semiconductor-based devices are forbidden in QSH edge states due to a selection rule. Also, electrons in QSH edge states are described by a massless Dirac fermion theory rather than the conventional Schrödinger-like parabolic band, so their response to an electromagnetic field is intrinsically affected by a peculiar effect known as the chiral anomaly. Here, the authors analyze this problem in the mesoscopic regime. They show that, when a spatially localized electric pulse is applied at the edge of a QSH system, helical electron wave packets can be photoexcited by purely intrabranch electrical transitions, without invoking the magnetic Zeeman coupling or transitions to bulk states. At the end of the pulse, the wave packets counter propagate with opposite spin orientations, keeping their space profile unaltered. Notably, the authors find that the space profile of the photoexcited electron wave packets is independent of the temperature and chemical potential of the initial equilibrium state. Instead, the profile depends purely on the applied electric pulse, in a linear manner, as a signature of the chiral anomaly. Then authors discuss how the wave packet profile can be tailored by the electric pulse parameters, for both low and finite frequencies.

Double quantum dots play an important role in the field of semiconductor and carbon nanotube quantum dots. They have resulted in, for example, correlated electron physics beyond the single spin-1/2 Kondo system and the realization of qubits for quantum computation. Using organic molecules to create a double quantum dot can be beneficial due to the larger energy scales present as compared to its more extended counterparts. Furthermore, they open up the possibility to investigate interactions between spins and perform coherent experiments on electrons in organic molecules. In this article, the authors experimentally investigate charge transport through a three-terminal single-molecule junction. The data shows features in transport that arise from the broken conjugation in dihydro-anthracene, which localizes π electrons and creates a set of nearly degenerate orbitals. The ferromagnetic and antiferromagnetic interactions are of the same order of magnitude, so that the singlet and triplet states are close in energy. These findings thus demonstrate a double quantum dot programmed in a single molecule due to its broken conjugation. This research is a starting point for further experiments, whereby with chemical means the interaction between the two dots can be lowered to observe Pauli spin-blockade and investigate spin coherent effects in single molecules.
