Phys. Rev. B 93, 201104(R) (2016) - Published 11 May, 2016

The search for new topological phases of matter is a major new direction in condensed matter physics. Recent experimental realizations of Dirac and Weyl semimetal phases pave the way to look for other exotic phases of matter in real materials. In this paper, the authors present a systematic angle-resolved photoemission spectroscopy study of ZrSiS, a potential topological nodal semimetal candidate. Their systematic measurements establish the spinless nodal fermion semimetal phase in ZrSiS, which is supported by their first-principles calculations. This work puts forward the ZrSiS-type material family as a new platform to explore exotic states of quantum matter.

Gigantic directional asymmetry of luminescence in multiferroic CuB2O4

S. Toyoda, N. Abe, and T. Arima

Phys. Rev. B 93, 201109(R) (2016) - Published 20 May, 2016

Multiferroic materials that simultaneously show electricity and magnetism provide an interesting playground for novel optical phenomena. One example is nonreciprocity, a change in optical properties with the reversal of the propagation direction of light. In this paper, the authors report that the luminescence intensity in multiferroic CuB2O4 changes by 70% between the opposite directions of the emitted light. The observed asymmetry is about 100 times larger than the previously reported value. They demonstrate that the gigantic directional asymmetry of luminescence provides a tool to visualize the antiferromagnetic domain structure, which is impossible using the conventional linear optical Faraday or Kerr effects.

Role of excited states in Shockley-Read-Hall recombination in wide-band-gap semiconductors

Audrius Alkauskas, Cyrus E. Dreyer, John L. Lyons, and Chris G. Van de Walle

Phys. Rev. B 93, 201304(R) (2016) - Published 25 May, 2016

Defect-assisted nonradiative Shockley-Read-Hall recombination is an important process in wide-band-gap semiconductors. However, nonradiative capture rates decrease exponentially with the energy of the transition, and therefore the mechanisms by which such recombination can take place are unclear. The authors show here that excited states of defects play a key role in turning specific defects into efficient nonradiative centers. The wider the band gap of the material, the greater a role these excited states are likely to play. Specifically, the authors can explain why certain gallium vacancy complexes are efficient nonradiative centers in group-III nitrides, the key materials for solid-state lighting.

Non-Abelian topological spin liquids from arrays of quantum wires or spin chains

Phys. Rev. B 93, 205123 (2016) - Published 13 May, 2016

In this paper, a family of non-Abelian topologically ordered states are built from arrays of quantum wires with fine-tuned electron-electron interactions. With the help of non-Abelian bosonization, the decoupled wires are described by conformal field theories. Electron-electron interactions are chosen to gap all conformal field theories except the one that describes the edge state. Hence, the construction makes it easy to engineer different topological ordered states. The authors prescribe, in particular, how to arrive at all the edge states described by the unitary conformal field theory minimal models using the spin degrees of freedom of the quantum wires alone. The construction provides a bridge between the field theory descriptions and the microscopic models of topological ordered states.

Ca3P2 and other topological semimetals with line nodes and drumhead surface states

Y.-H. Chan, Ching-Kai Chiu, M. Y. Chou, and Andreas P. Schnyder

Phys. Rev. B 93, 205132 (2016) - Published 17 May, 2016

Topological nodal line semimetals exhibit protected one-dimensional Fermi lines, which arise due to an intricate interplay between the symmetry and topology of the electronic wave functions. In this paper, the authors derive the Z invariants that guarantee the stability of the line nodes in the bulk under reflection symmetry and show that a quantized Berry phase (i.e, a Z2 invariant) leads to the appearance of protected surfaces states, which take the shape of a drumhead. Most importantly, a relation between the Z invariant, which characterizes the bulk, and the quantized Berry phase is derived. This relation is generally applicable to any topological nodal line semimetal with or without spin-orbit coupling. Moreover, it is shown that the Berry phase invariant can be simply obtained by computing the reflection parity eigenvalues. As a representative example of a topological nodal line semimetal, the authors examine Ca3P2, which has been identified as an ideal system with the line nodes at the Fermi energy. Using numerical calculations, they show that the drumhead surface state of Ca3P2 has a rather weak dispersion, which implies that correlation effects are enhanced at the surface.

Precise effective masses from density functional perturbation theory

J. Laflamme Janssen, Y. Gillet, S. Poncé, A. Martin, M. Torrent, and X. Gonze

Phys. Rev. B 93, 205147 (2016) - Published 25 May, 2016

Effective mass calculations are currently based on finite-difference estimations of electronic band curvature (or Hessians). This requires an extra convergence study that can easily reach problematic levels if not carefully monitored. While these issues could be considered hindrances in traditional first-principles calculations, they become more fundamental limitations within the quickly expanding field of high-throughput material design. To eliminate these issues, a new method is developed based on density functional perturbation theory (DFPT) that directly computes the Hessian of DFT bands. The new method includes a generalized k.p formalism within which it is possible to define effective masses at degenerate band extrema. The result is a simulation method of effective masses that is general, robust, and simple to use, which should open new routes in high-throughput material design.

Phonon analog of topological nodal semimetals

Hoi Chun Po, Yasaman Bahri, and Ashvin Vishwanath

Phys. Rev. B 93, 205158 (2016) - Published 31 May, 2016

Topological band structures are ubiquitous in both fermionic and bosonic problems, but conventional wisdom holds that the topological features in a noninteracting bosonic system are only visible to finite-frequency probes. Utilizing a recently proposed boson-to-fermion mapping, the authors demonstrate that topological gapless phonon modes can in fact be brought all the way down to zero frequency. In particular, they construct spring-mass models that are analogs of two-dimensional Dirac semimetals, and hence feature topological zero-frequency phonon modes. These zero modes are physically distinct from the familiar Goldstone phonons, and are in fact present even in pinned disordered systems due to topological protection.

Weak (anti)localization in tubular semiconductor nanowires with spin-orbit coupling

Michael Kammermeier, Paul Wenk, John Schliemann, Sebastian Heedt, and Thomas Schäpers

Phys. Rev. B 93, 205306 (2016) - Published 19 May, 2016

Electrons in semiconductor nanowires can be radially confined to form a thin tubular conductive channel a few nanometers below the surface. The peculiar potential landscape, which can be either a result of Fermi level pinning due to surface reconstruction or band mismatch at the heterointerface in core/shell nanowires, gives rise to both Rashba and Dresselhaus spin-orbit coupling (SOC). By utilizing kp theory, the authors have developed models for the SOC in nanowires with zinc-blende crystal structure for various nanowire growth directions. Taking advantage of these models, the weak (anti)localization correction Δσ to the static Drude conductivity is derived. Finally, the theory is fitted to experimental data of an undoped <111> InAs nanowire device, which exhibits a gate-controlled crossover from positive to negative magnetoconductivity. Thereby, the authors extract transport parameters and quantify the distinct types of SOC individually. The close agreement of theory and experiment suggests that the model provides reliable information and underlines the relevance of Dresselhaus SOC, which was previously often considered absent.

Dielectric function and plasmons in graphene: A self-consistent-field calculation within a Markovian master equation formalism

F. Karimi, A. H. Davoody, and I. Knezevic

Phys. Rev. B 93, 205421 (2016) - Published 12 May, 2016

The challenge of understanding the optical response and plasmon behavior in nanostructured materials, such as graphene and its nanoribbons, lies in describing screening in the presence of several concurrent electron scattering mechanisms. In this paper, the authors present a technique for calculating the dielectric function of nanostructures with an arbitrary band dispersion and Bloch wave functions. To calculate the linear response of a dissipative electronic system to an external electromagnetic field, the authors derive a quantum master equation within a self-consistent-field approach and solve it along with full-wave electromagnetic equations. This technique accurately captures interband electron-hole pair generation, as well as both interband and intraband electron scattering with phonons and impurities. The technique is employed to calculate the dielectric function, complex conductivity, as well as plasmon dispersion and propagation length for supported graphene. Plasmon propagation lengths are comparable on polar and nonpolar substrates and are on the order of tens of nanometers, considerably shorter than previously reported. They improve with fewer impurities, at lower temperatures, and at higher carrier densities.

Local density of states and its mesoscopic fluctuations near the transition to a superconducting state in disordered systems

I. S. Burmistrov, I. V. Gornyi, and A. D. Mirlin

Phys. Rev. B 93, 205432 (2016) - Published 20 May, 2016

Disordered superconductors show remarkable physics governed by the interplay of superconductivity and Anderson localization. The competition between these phenomena leads to a quantum phase transition: the superconductor-insulator transition (SIT). In this paper, the authors develop a theory of local density of states (LDOS) – including its average and mesoscopic fluctuations – as measured in tunneling experiments near the SIT. They use the nonlinear sigma-model renormalization-group framework (“fermionic approach”) and treat systems with short-range and Coulomb interactions on equal footing. The average LDOS obtained shows a pronounced depletion around the Fermi energy, both in the metallic phase (i.e., above the superconducting critical temperature) and in the insulating phase near the SIT. The LDOS fluctuations are found to be particularly strong for the case of short-range interactions. The findings compare well with experimental observations of depletion of LDOS and of its large point-to-point fluctuations in the metallic and insulating phases near the SIT in TiN, InO, and NbN films. The observed effects are thus intrinsic properties of a macroscopically homogeneous system and do not require any additional assumptions, such as granularity.

Topological nodal line semimetals exhibit protected one-dimensional Fermi lines, which arise due to an intricate interplay between the symmetry and topology of the electronic wave functions. In this paper, the authors derive the Z invariants that guarantee the stability of the line nodes in the bulk under reflection symmetry and show that a quantized Berry phase (i.e, a Z2 invariant) leads to the appearance of protected surfaces states, which take the shape of a drumhead. Most importantly, a relation between the Z invariant, which characterizes the bulk, and the quantized Berry phase is derived. This relation is generally applicable to any topological nodal line semimetal with or without spin-orbit coupling. Moreover, it is shown that the Berry phase invariant can be simply obtained by computing the reflection parity eigenvalues. As a representative example of a topological nodal line semimetal, the authors examine Ca3P2, which has been identified as an ideal system with the line nodes at the Fermi energy.

Effective mass calculations are currently based on finite-difference estimations of electronic band curvature (or Hessians). This requires an extra convergence study that can easily reach problematic levels if not carefully monitored. While these issues could be considered hindrances in traditional first-principles calculations, they become more fundamental limitations within the quickly expanding field of high-throughput material design. To eliminate these issues, a new method is developed based on density functional perturbation theory (DFPT) that directly computes the Hessian of DFT bands. The new method includes a generalized k.p formalism within which it is possible to define effective masses at degenerate band extrema. The result is a simulation method of effective masses that is general, robust, and simple to use, which should open new routes in high-throughput material design.

Topological band structures are ubiquitous in both fermionic and bosonic problems, but conventional wisdom holds that the topological features in a noninteracting bosonic system are only visible to finite-frequency probes. Utilizing a recently proposed boson-to-fermion mapping, the authors demonstrate that topological gapless phonon modes can in fact be brought all the way down to zero frequency. In particular, they construct spring-mass models that are analogs of two-dimensional Dirac semimetals, and hence feature topological zero-frequency phonon modes. These zero modes are physically distinct from the familiar Goldstone phonons, and are in fact present even in pinned disordered systems due to topological protection.

Phys. Rev. B 93, 205306 (2016) - Published 19 May, 2016

Electrons in semiconductor nanowires can be radially confined to form a thin tubular conductive channel a few nanometers below the surface. The peculiar potential landscape, which can be either a result of Fermi level pinning due to surface reconstruction or band mismatch at the heterointerface in core/shell nanowires, gives rise to both Rashba and Dresselhaus spin-orbit coupling (SOC). By utilizing kp theory, the authors have developed models for the SOC in nanowires with zinc-blende crystal structure for various nanowire growth directions. Taking advantage of these models, the weak (anti)localization correction Δσ to the static Drude conductivity is derived. Finally, the theory is fitted to experimental data of an undoped <111> InAs nanowire device, which exhibits a gate-controlled crossover from positive to negative magnetoconductivity. Thereby, the authors extract transport parameters and quantify the distinct types of SOC individually. The close agreement of theory and experiment suggests that the model provides reliable information and underlines the relevance of Dresselhaus SOC, which was previously often considered absent.

The challenge of understanding the optical response and plasmon behavior in nanostructured materials, such as graphene and its nanoribbons, lies in describing screening in the presence of several concurrent electron scattering mechanisms. In this paper, the authors present a technique for calculating the dielectric function of nanostructures with an arbitrary band dispersion and Bloch wave functions. To calculate the linear response of a dissipative electronic system to an external electromagnetic field, the authors derive a quantum master equation within a self-consistent-field approach and solve it along with full-wave electromagnetic equations. This technique accurately captures interband electron-hole pair generation, as well as both interband and intraband electron scattering with phonons and impurities. The technique is employed to calculate the dielectric function, complex conductivity, as well as plasmon dispersion and propagation length for supported graphene. Plasmon propagation lengths are comparable on polar and nonpolar substrates and are on the order of tens of nanometers, considerably shorter than previously reported. They improve with fewer impurities, at lower temperatures, and at higher carrier densities.

Phys. Rev. B 93, 205432 (2016) - Published 20 May, 2016

Disordered superconductors show remarkable physics governed by the interplay of superconductivity and Anderson localization. The competition between these phenomena leads to a quantum phase transition: the superconductor-insulator transition (SIT). In this paper, the authors develop a theory of local density of states (LDOS) – including its average and mesoscopic fluctuations – as measured in tunneling experiments near the SIT. They use the nonlinear sigma-model renormalization-group framework (“fermionic approach”) and treat systems with short-range and Coulomb interactions on equal footing. The average LDOS obtained shows a pronounced depletion around the Fermi energy, both in the metallic phase (i.e., above the superconducting critical temperature) and in the insulating phase near the SIT. The LDOS fluctuations are found to be particularly strong for the case of short-range interactions. The findings compare well with experimental observations of depletion of LDOS and of its large point-to-point fluctuations in the metallic and insulating phases near the SIT in TiN, InO, and NbN films. The observed effects are thus intrinsic properties of a macroscopically homogeneous system and do not require any additional assumptions, such as granularity.
