Emergent anomalies and generalized Luttinger theorems in metals and semimetals

Chong Wang, Alexander Hickey, Xuzhe Ying, and A. A. Burkov

Phys. Rev. B 104, 235113 (2021) - Published 7 December, 2021

Whether a given material is a metal or an insulator is determined by a single parameter, the number of electrons per unit cell per spin, that is, by the filling number. When the latter is integer, the material is an insulator or a compensated semimetal. When it is fractional, the material is a metal with a Fermi surface, enclosing a volume in momentum space, determined by the fractional part of the filling – a statement known as Luttinger’s theorem. Topological semimetals provide a realization of the metallic phase, distinct from ordinary metals, as they exist at integer fillings, which normally correspond to insulators. Here, the authors develop a framework that unifies Luttinger’s theorem for ordinary metals and analogous exact statements for topological semimetals. They use the language of quantum anomalies of the emergent low-energy charge conservation symmetry at each point on the Fermi surface. This framework allows one to connect topological responses in all nodal semimetals to their low-energy properties, such as the distance between the point nodes in momentum space or the area, enclosed by the nodal line.

Local versus nonlocal correlation effects in interacting quantum spin Hall insulators

L. Crippa, A. Amaricci, S. Adler, G. Sangiovanni, and M. Capone

Phys. Rev. B 104, 235117 (2021) - Published 8 December, 2021

When supplemented by a local electron-electron interaction, the Bernevig-Hughes-Zhang model becomes an ideal platform to investigate correlated topological phases. Employing DMFT-based cluster methods, the authors identify two different parameter regions: (i) for intermediate to large orbital polarization, spatially local correlations suffice to describe the interaction-induced transition from trivial to nontrivial topology, confirming the single-site DMFT picture; (ii) in contrast, nonlocal self-energy effects become predominant at low orbital polarization and near the transition from semimetal to Mott phase.

Photoionization of negatively charged NV centers in diamond: Theory and ab initio calculations

Lukas Razinkovas, Marek Maciaszek, Friedemann Reinhard, Marcus W. Doherty, and Audrius Alkauskas

Phys. Rev. B 104, 235301 (2021) - Published 6 December, 2021

A nitrogen-vacancy center in diamond is a defect that has become a key platform for testing and eventually implementing various quantum technologies. During optical illumination, the center can change its charge state via a photoionization process. In this work, the authors present ab initio calculations of photoionization thresholds and cross sections of the nitrogen-vacancy center. The results explain several puzzling experimental findings.

Strong electron-electron interactions in Si/SiGe quantum dots

H. Ekmel Ercan, S. N. Coppersmith, and Mark Friesen

Phys. Rev. B 104, 235302 (2021) - Published 13 December, 2021

The authors implement a nonperturbative method for calculating the effects of strong electron-electron interactions, nearly degenerate electronic valleys, and interface disorder in multielectron silicon quantum dots. They show that all three ingredients play an important role in qubit experiments, and that Wigner-molecule physics in silicon can be substantially different from that in materials without valley degeneracy. The results provide key insights for the design and implementation of quantum dot qubits in silicon.

Electrical control of the g tensor of the first hole in a silicon MOS quantum dot

S. D. Liles, F. Martins, D. S. Miserev, A. A. Kiselev, I. D. Thorvaldson, M. J. Rendell, I. K. Jin, F. E. Hudson, M. Veldhorst, K. M. Itoh, O. P. Sushkov, T. D. Ladd, A. S. Dzurak, and A. R. Hamilton

Phys. Rev. B 104, 235303 (2021) - Published 17 December, 2021

Hole spins are highly promising for spin-qubit technology due to the ability to electrically manipulate the hole g tensor. However, gaps remain in our understanding of the mechanisms that couple hole spins to electric fields. Here, the authors investigate the effect of unintentional strain on the spin state of a single hole confined in a metal-oxide-semiconductor (MOS) quantum dot. Results show that the metal electrodes produce a nonuniform strain profile, resulting in nanometer-scale variations in the heavy-hole–light-hole splitting. Therefore, local electric fields can be used to displace the hole wavefunction relative to the nonuniform strain, allowing a mechanism for electric control of the hole g tensor.

Intersubband excitations in ultrathin core-shell nanowires in the one-dimensional quantum limit probed by resonant inelastic light scattering

Sebastian Meier, Paulo E. Faria Junior, Ferdinand Haas, Emma-Sophia Heller, Florian Dirnberger, Viola Zeller, Tobias Korn, Jaroslav Fabian, Dominique Bougeard, and Christian Schüller

Phys. Rev. B 104, 235307 (2021) - Published 22 December, 2021

The observation of electronic Raman scattering in one-dimensional semiconductors has so far been limited to arrays of laterally structured quantum wells. Recent progress in the growth of core-shell nanowires has opened the possibility to reach the quantum confinement regime for single nanowires. Here, the authors present measurements of the one-dimensional subband structure of single wurtzite-phase GaAs nanowires by resonant Raman spectroscopy. The obtained energetic distances between consecutive electron or hole subbands are nicely reproduced by realistic k∙p band structure calculations.

Subwavelength focusing by engineered power-flow conformal metamirrors

Hamidreza Taghvaee, Fu Liu, Ana Díaz-Rubio, and Sergei Tretyakov

Phys. Rev. B 104, 235409 (2021) - Published 8 December, 2021

It is highly desirable to break the diffraction limit on the resolution of optical devices and achieve subwavelength focusing. Here, the authors show that curved and inhomogeneous reflectors offer a practical method for achieving this goal. The surface profile of the focusing reflector is designed to be tangential to the desired power flow so that the metamirror can be described locally by lossless impedance boundaries and can be easily implemented using simple lossless meta-atoms. We envisage some practical applications of subwavelength focusing that become possible using this method.

Relativistic first-principles theory of Yu-Shiba-Rusinov states applied to Mn adatoms and Mn dimers on Nb(110)

Bendegúz Nyári, András Lászlóffy, László Szunyogh, Gábor Csire, Kyungwha Park, and Balázs Ujfalussy

Phys. Rev. B 104, 235426 (2021) - Published 21 December, 2021

The authors introduce a first-principles material-specific description of Yu-Shiba-Rusinov (YSR) states where relativity, superconductivity, magnetism, and the entire host electronic structure are treated on the same footing. They achieve this by solving the fully relativistic Bogoliubov–de Gennes equations via band-theoretical methods for the entire host-embedded impurity system. The method is used to make a direct comparison with the most recent experiments. Furthermore, one immediately gains a deeper insight into the formation of the YSR states by artificially manipulating the exchange field of the impurity, the spin-orbit coupling, and the induced moments. Comparison with experiments is extended to magnetic dimers, where the authorsdiscuss the hybridization of the YSR states in the ferromagnetic and antiferromagnetic configurations. The importance of such first-principles calculations for the interpretation of future experiments on similar or longer chains and on other nanostructures with a zero-bias peak has been elucidated.

Tunneling in the Brillouin zone: Theory of backscattering in valley Hall edge channels

Tirth Shah, Florian Marquardt, and Vittorio Peano

Phys. Rev. B 104, 235431 (2021) - Published 27 December, 2021

In many time-reversal-symmetric implementations of topological transport of classical waves, backscattering is nominally forbidden only within a description that does not include large momentum transfer. Here, the authors introduce a more refined picture, in which backscattering is induced by tunneling transitions in the reciprocal (quasimomentum) space. They predict enhanced backscattering at discrete centers, whose locations depend both on the energy and the local slope of the domain wall. The theory provides guidance to the design of future topological devices with reduced backscattering.

Van der Waals anomaly: Analog of dark energy with ultracold atoms

Hole spins are highly promising for spin-qubit technology due to the ability to electrically manipulate the hole g tensor. However, gaps remain in our understanding of the mechanisms that couple hole spins to electric fields. Here, the authors investigate the effect of unintentional strain on the spin state of a single hole confined in a metal-oxide-semiconductor (MOS) quantum dot. Results show that the metal electrodes produce a nonuniform strain profile, resulting in nanometer-scale variations in the heavy-hole–light-hole splitting. Therefore, local electric fields can be used to displace the hole wavefunction relative to the nonuniform strain, allowing a mechanism for electric control of the hole g tensor.

The observation of electronic Raman scattering in one-dimensional semiconductors has so far been limited to arrays of laterally structured quantum wells. Recent progress in the growth of core-shell nanowires has opened the possibility to reach the quantum confinement regime for single nanowires. Here, the authors present measurements of the one-dimensional subband structure of single wurtzite-phase GaAs nanowires by resonant Raman spectroscopy. The obtained energetic distances between consecutive electron or hole subbands are nicely reproduced by realistic k∙p band structure calculations.

It is highly desirable to break the diffraction limit on the resolution of optical devices and achieve subwavelength focusing. Here, the authors show that curved and inhomogeneous reflectors offer a practical method for achieving this goal. The surface profile of the focusing reflector is designed to be tangential to the desired power flow so that the metamirror can be described locally by lossless impedance boundaries and can be easily implemented using simple lossless meta-atoms. We envisage some practical applications of subwavelength focusing that become possible using this method.

Phys. Rev. B 104, 235426 (2021) - Published 21 December, 2021

The authors introduce a first-principles material-specific description of Yu-Shiba-Rusinov (YSR) states where relativity, superconductivity, magnetism, and the entire host electronic structure are treated on the same footing. They achieve this by solving the fully relativistic Bogoliubov–de Gennes equations via band-theoretical methods for the entire host-embedded impurity system. The method is used to make a direct comparison with the most recent experiments. Furthermore, one immediately gains a deeper insight into the formation of the YSR states by artificially manipulating the exchange field of the impurity, the spin-orbit coupling, and the induced moments. Comparison with experiments is extended to magnetic dimers, where the authorsdiscuss the hybridization of the YSR states in the ferromagnetic and antiferromagnetic configurations. The importance of such first-principles calculations for the interpretation of future experiments on similar or longer chains and on other nanostructures with a zero-bias peak has been elucidated.

Phys. Rev. B 104, 235431 (2021) - Published 27 December, 2021

In many time-reversal-symmetric implementations of topological transport of classical waves, backscattering is nominally forbidden only within a description that does not include large momentum transfer. Here, the authors introduce a more refined picture, in which backscattering is induced by tunneling transitions in the reciprocal (quasimomentum) space. They predict enhanced backscattering at discrete centers, whose locations depend both on the energy and the local slope of the domain wall. The theory provides guidance to the design of future topological devices with reduced backscattering.
