Nontrivial Berry phase and type-II Dirac transport in the layered material PdTe2

Fucong Fei, Xiangyan Bo, Rui Wang, Bin Wu, Juan Jiang, Dongzhi Fu, Ming Gao, Hao Zheng, Yulin Chen, Xuefeng Wang, Haijun Bu, Fengqi Song, Xiangang Wan, Baigeng Wang, and Guanghou Wang

Phys. Rev. B 96, 041201(R) (2017) - Published 5 July, 2017

Recently, the picture of type-II energy dispersion with broken Lorentz invariance has been adapted from Weyl to Dirac fermions. It is demonstrated in PdTe2 in this paper by extensive evidence from electrical transport, de Haas–van Alphen oscillations, first-principles calculations, and angle-resolved photoemission spectroscopy. The type-II Dirac cone looks like a pinnacle in momentum space. It may be cut by the Fermi level with the result of a pair of Dirac pockets (of p/n type), whose sizes change dramatically with the Fermi level. The nontrivial Berry phase of the hole pocket is also displayed. This also means a nonvanishing density of states in the whole Dirac cones, which makes PdTe2 an improved platform for possible topological superconductors and Majorana fermions

Interacting nodal-line semimetal: Proximity effect and spontaneous symmetry breaking

Bitan Roy

Phys. Rev. B 96, 041113(R) (2017) - Published 12 July, 2017

The nodal-line semimetal stands out as a paradigmatic representative of a gapless topological phase of matter that supports linearly dispersing quasiparticles around an isolated closed loop in the bulk and accommodates drumhead shaped surface states. The author demonstrates an intriguing possibility of realizing either charge or spin order on the surface of this system for arbitrarily weak Coulomb repulsion. When onsite Hubbard repulsion dominates, each surface becomes ferromagnetic with its moment pointing in opposite directions on complementary faces, which yields a global antiferromagnet. As shown numerically, surface ordering via proximity effect can in turn induce charge or spin order in the bulk at weak coupling, making the proposed scenario for spontaneous symmetry breaking relevant for materials, such as Ca3P2 and PbTaSe2, specifically in a thin-film geometry.

Role of commensurability of spin order for optical magnetoelectric effect with electromagnons in multiferroic YMn2O5

R. Masuda, Y. Kaneko, Y. Yamasaki, Y. Tokura, and Y. Takahashi

Phys. Rev. B 96, 041117(R) (2017) - Published 17 July, 2017

Multiferroic phases of materials like YM2O5 feature an optical magnetoelectric effect on the resonance of the electromagnon. The effect manifests itself in nonreciprocal directional dichroism. Here, the authors examine the role of the commensurability of noncollinear spin order for the optical magnetoelectric effect for two types of electromagnon. For the electromagnon driven by the exchange striction, the crucial role of the commensurability is indicated by the suppression of the directional dichroism by the magnetic phase transition. On the other hand, the gapped electromagnon due to the spin-current mechanism is identified by the directional dichroism, regardless of (in)commensurability. These results provide new insights into the light-matter interaction driven by dynamical magnetoelectric coupling.

Effect of SU(2) symmetry on many-body localization and thermalization

Ivan V. Protopopov, Wen Wei Ho, and Dmitry A. Abanin

Phys. Rev. B 96, 041122(R) (2017) - Published 21 July, 2017

Many-body localization (MBL) enables new nonergodic dynamical phases of matter that avoid the fate of thermalization. Do other ergodicity-breaking phases beyond the MBL paradigm exist? Here, the authors introduce a method for constructing and probing the stability of candidate nonergodic phases. As an example, they consider disordered spin systems, in which a non-Abelian SU(2) symmetry precludes the conventional MBL phase that is characterized by quasilocal integrals of motion and area-law entanglement entropy of eigenstates. Instead, the authors construct a candidate nonergodic phase characterized by eigenstates having logarithmic scaling of entanglement entropy. They find that the phase is only marginally unstable and, therefore, nonthermal yet non-MBL dynamics can be observed in such disordered systems.

Composite Weyl nodes stabilized by screw symmetry with and without time-reversal invariance

Stepan S. Tsirkin, Ivo Souza, and David Vanderbilt

Phys. Rev. B 96, 045102 (2017) - Published 5 July, 2017

The authors demonstrate that in nonmagnetic crystals with threefold or sixfold symmetry, such as trigonal Te or hexagonal NbSi2, three linear band crossings (Weyl nodes) of the same chirality can merge at a high-symmetry point on the symmetry axis, forming a triple Weyl node with a cubic off-axis dispersion. If time reversal invariance is broken, the triple node in NbSi2 is displaced from the symmetry point along the axis, while its off-axis dispersion becomes quadratic. In Te, however, it splits into three linear Weyl nodes, since threefold symmetry is unable to stabilize triple Weyl nodes in the absence of time reversal symmetry.

Nonequilibrium steady states and transient dynamics of conventional superconductors under phonon driving

Yuta Murakami, Naoto Tsuji, Martin Eckstein, and Philipp Werner

Phys. Rev. B 96, 045125 (2017) - Published 19 July, 2017

The optical manipulation of phonon degrees of freedom can change the effective interactions in solids and potentially enhance superconductivity. However, heating and nonthermal energy distributions need to be considered to understand the ultimate effects of such a driving on ordered states. Using nonequilibrium dynamical mean field theory in the Kadanoff-Baym and Floquet implementation, the authors systematically discuss the effects of parametric phonon driving on conventional superconductivity. Both the transient dynamics of isolated systems and the nonequilibrium steady states in driven-dissipative systems are considered. While the phonon-mediated attractive interaction can be enhanced in certain driving regimes because of Floquet phonon sidebands, the heating and nonthermal distribution effects dominate and generically result in a suppression of superconductivity.

Nearly massless Dirac fermions and strong Zeeman splitting in the nodal-line semimetal ZrSiS probed by de Haas–van Alphen quantum oscillations

Jin Hu, Zhijie Tang, Jinyu Liu, Yanglin Zhu, Jiang Wei, and Zhiqiang Mao

Phys. Rev. B 96, 045127 (2017) - Published 19 July, 2017

Topological semimetals harbor relativistic fermions featuring light effective mass, high mobility, and a nontrivial Berry phase. Quantum oscillations are an effective means to probe the properties of relativistic fermions. In the Dirac nodal-line semimetal ZrSiS, the extremely high Dirac fermion density gives rise to very strong de Haas–van Alphen quantum oscillations even at low magnetic fields, by which nearly massless Dirac fermions with surprisingly strong Zeeman effect are revealed.

Hall number across a van Hove singularity

Akash V. Maharaj, Ilya Esterlis, Yi Zhang, B. J. Ramshaw, and S. A. Kivelson

Phys. Rev. B 96, 045132 (2017) - Published 24 July, 2017

The high-field Hall number directly measures the carrier density in metals with closed Fermi surfaces. However, no general theorem is known to govern the behavior of the Hall number in systems with open Fermi surfaces or the critical behavior across a Lifshitz transition from a closed to open topology. Using Boltzmann transport theory, the authors derive analytic expressions for the behavior of the Hall number through such a transition, and recent experiments on hole doped cuprate superconductors that suggest a sudden drop of the Hall number below optimal doping are shown to be consistent with a nematicity-induced Lifshitz transition.

Cheshire charge in (3+1)-dimensional topological phases

Dominic V. Else and Chetan Nayak

Phys. Rev. B 96, 045136 (2017) - Published 25 July, 2017

The authors examine the phenomenon of “Cheshire charge” in topological phases of matter in three spatial dimensions. A looplike excitation is said to carry Cheshire charge if the charge is not locally detectable, that is, it can only be observed by a nonlocal process such as shrinking the loop to a point. The authors show that “Cheshire charge” is a generic feature of three-dimensional topological phases. They relate it to other features of these phases, such as three-loop braiding, as well as to higher-category theory that is hypothesized to be the general mathematical framework describing three-dimensional topological phases.

Closing the gap between spatial and spin dynamics of electrons at the metal-to-insulator transition

J. G. Lonnemann, E. P. Rugeramigabo, M. Oestreich, and J. Hübner

Phys. Rev. B 96, 045201 (2017) - Published 5 July, 2017

The spin dynamics of electrons at the metal-to-insulator transitionis a surprisingly complex problem in semiconductor physics, where many claims to complete solution have often been made in the past. In this work, the authors employ magnetotransport measurements in n-doped GaAs and identify unambiguously the underlying electron scattering mechanisms in a contiguous set of specially designed n-doped bulk semiconductor structures. They deduce the doping dependent scattering angles and combine these findings with highly accurate optical measurements of the spin dynamics. This complementary analysis allows for a complete quantitative modeling of the electron spin relaxation over the entire range from weakly interacting to fully delocalized electrons.

Impact of g-factors and valleys on spin qubits in a silicon double quantum dot

Phys. Rev. B 96, 045302 (2017) - Published 5 July, 2017

Silicon quantum dots represent a promising platform for quantum computing, in which the spin states of single electrons can be used as qubits. Here, the authors examine the effect of the intervalley spin-orbit coupling on the resonance spectrum of a single qubit and propose a new type of universal two-qubit operation that utilizes the small g-factor difference between two exchange-coupled quantum dots. Both findings have significant implications for the development of larger-scale spin qubit systems.

Inversion of the exciton built-in dipole moment in In(Ga)As quantum dots via nonlinear piezoelectric effect

Phys. Rev. B 96, 045414 (2017) - Published 13 July, 2017

Piezoelectric effects can strongly affect the position and shape of the electron and hole wave functions in compound semiconductors quantum dots (QDs). From the point of view of theoretical semiconductor physics, this is a well-documented notion. From an experimental point of view, however, the extreme sensitivity of the electronic properties of QDs to tiny variations of their shape, size, and composition makes it very challenging to single out the effect of piezoelectricity, which is often neglected in the analysis of experimental data. Here, the authors demonstrate that externally induced piezoelectric fields can be used for wave function engineering and to even force an inversion of the exciton built-in dipole moment in the very same QD. Detailed calculations based on k.p theory disclose that the inversion of the exciton dipole is driven by the nonlinear terms of the piezoelectric fields. These findings shine new light on the role and the possible exploitation of piezoelectric effects in semiconductor QDs.

Symmetric operation of the resonant exchange qubit

Phys. Rev. B 96, 045443 (2017) - Published 31 July, 2017

Spin states of a three-electron system can encode one quantum bit in such a way that universal qubit control by voltage pulses becomes possible. In this work, a triple-dot qubit is operated in a highly symmetric charge configuration, using resonant radio-frequency voltage pulses applied to one gate electrode. The authors show that careful symmetrization reduces the susceptibility of the qubit frequency to voltage fluctuations by more than an order of magnitude, compared to conventional triple-dot spin qubits. Combining voltage control with symmetric operating regimes may lead to multiqubit processors based on semiconducting spin qubits that at the same time alleviate decoherence due to electrical noise.

Composite Weyl nodes stabilized by screw symmetry with and without time-reversal invariance

Phys. Rev. B 96, 045102 (2017) - Published 5 July, 2017

The authors demonstrate that in nonmagnetic crystals with threefold or sixfold symmetry, such as trigonal Te or hexagonal NbSi2, three linear band crossings (Weyl nodes) of the same chirality can merge at a high-symmetry point on the symmetry axis, forming a triple Weyl node with a cubic off-axis dispersion. If time reversal invariance is broken, the triple node in NbSi2 is displaced from the symmetry point along the axis, while its off-axis dispersion becomes quadratic. In Te, however, it splits into three linear Weyl nodes, since threefold symmetry is unable to stabilize triple Weyl nodes in the absence of time reversal symmetry.

Nonequilibrium steady states and transient dynamics of conventional superconductors under phonon driving

Phys. Rev. B 96, 045125 (2017) - Published 19 July, 2017

The optical manipulation of phonon degrees of freedom can change the effective interactions in solids and potentially enhance superconductivity. However, heating and nonthermal energy distributions need to be considered to understand the ultimate effects of such a driving on ordered states. Using nonequilibrium dynamical mean field theory in the Kadanoff-Baym and Floquet implementation, the authors systematically discuss the effects of parametric phonon driving on conventional superconductivity. Both the transient dynamics of isolated systems and the nonequilibrium steady states in driven-dissipative systems are considered. While the phonon-mediated attractive interaction can be enhanced in certain driving regimes because of Floquet phonon sidebands, the heating and nonthermal distribution effects dominate and generically result in a suppression of superconductivity.

Topological semimetals harbor relativistic fermions featuring light effective mass, high mobility, and a nontrivial Berry phase. Quantum oscillations are an effective means to probe the properties of relativistic fermions. In the Dirac nodal-line semimetal ZrSiS, the extremely high Dirac fermion density gives rise to very strong de Haas–van Alphen quantum oscillations even at low magnetic fields, by which nearly massless Dirac fermions with surprisingly strong Zeeman effect are revealed.

The high-field Hall number directly measures the carrier density in metals with closed Fermi surfaces. However, no general theorem is known to govern the behavior of the Hall number in systems with open Fermi surfaces or the critical behavior across a Lifshitz transition from a closed to open topology. Using Boltzmann transport theory, the authors derive analytic expressions for the behavior of the Hall number through such a transition, and recent experiments on hole doped cuprate superconductors that suggest a sudden drop of the Hall number below optimal doping are shown to be consistent with a nematicity-induced Lifshitz transition.

Cheshire charge in (3+1)-dimensional topological phases

Phys. Rev. B 96, 045136 (2017) - Published 25 July, 2017

The authors examine the phenomenon of “Cheshire charge” in topological phases of matter in three spatial dimensions. A looplike excitation is said to carry Cheshire charge if the charge is not locally detectable, that is, it can only be observed by a nonlocal process such as shrinking the loop to a point. The authors show that “Cheshire charge” is a generic feature of three-dimensional topological phases. They relate it to other features of these phases, such as three-loop braiding, as well as to higher-category theory that is hypothesized to be the general mathematical framework describing three-dimensional topological phases.

The spin dynamics of electrons at the metal-to-insulator transitionis a surprisingly complex problem in semiconductor physics, where many claims to complete solution have often been made in the past. In this work, the authors employ magnetotransport measurements in n-doped GaAs and identify unambiguously the underlying electron scattering mechanisms in a contiguous set of specially designed n-doped bulk semiconductor structures. They deduce the doping dependent scattering angles and combine these findings with highly accurate optical measurements of the spin dynamics. This complementary analysis allows for a complete quantitative modeling of the electron spin relaxation over the entire range from weakly interacting to fully delocalized electrons.

Silicon quantum dots represent a promising platform for quantum computing, in which the spin states of single electrons can be used as qubits. Here, the authors examine the effect of the intervalley spin-orbit coupling on the resonance spectrum of a single qubit and propose a new type of universal two-qubit operation that utilizes the small g-factor difference between two exchange-coupled quantum dots. Both findings have significant implications for the development of larger-scale spin qubit systems.

Piezoelectric effects can strongly affect the position and shape of the electron and hole wave functions in compound semiconductors quantum dots (QDs). From the point of view of theoretical semiconductor physics, this is a well-documented notion. From an experimental point of view, however, the extreme sensitivity of the electronic properties of QDs to tiny variations of their shape, size, and composition makes it very challenging to single out the effect of piezoelectricity, which is often neglected in the analysis of experimental data. Here, the authors demonstrate that externally induced piezoelectric fields can be used for wave function engineering and to even force an inversion of the exciton built-in dipole moment in the very same QD. Detailed calculations based on k.p theory disclose that the inversion of the exciton dipole is driven by the nonlinear terms of the piezoelectric fields. These findings shine new light on the role and the possible exploitation of piezoelectric effects in semiconductor QDs.

Spin states of a three-electron system can encode one quantum bit in such a way that universal qubit control by voltage pulses becomes possible. In this work, a triple-dot qubit is operated in a highly symmetric charge configuration, using resonant radio-frequency voltage pulses applied to one gate electrode. The authors show that careful symmetrization reduces the susceptibility of the qubit frequency to voltage fluctuations by more than an order of magnitude, compared to conventional triple-dot spin qubits. Combining voltage control with symmetric operating regimes may lead to multiqubit processors based on semiconducting spin qubits that at the same time alleviate decoherence due to electrical noise.
