Topological descendants of a multicritical Dirac semimetal with magnetism and strain

Lin-Lin Wang, Hoi Chun Po, Robert-Jan Slager, and Ashvin Vishwanath

Phys. Rev. B 104, 165107 (2021) - Published 5 October, 2021

The past decades have seen an ever increasing rise in classification and characterization of topological materials. One of the most important questions is how to control and manipulate topological phases. Here, the authors predict a multicritical topological paradigm in EuTl2. Starting from a paramagnetic Dirac semimetallic phase, a plethora of descendant topological phases are accessible with magnetism and strain, including Dirac and Weyl magnetic semimetals, axion insulators, and a variety of other topological crystalline insulators protected by different symmetries.

Non-Abelian statistics in light-scattering processes across interacting Haldane chains

Vladimir Gnezdilov, Vladimir Kurnosov, Yurii Pashkevich, Anup Kumar Bera, A. T. M. Nazmul Islam, Bella Lake, Bodo Lobbenmeier, Dirk Wulferding, and Peter Lemmens

Phys. Rev. B 104, 165118 (2021) - Published 11 October, 2021

The Haldane chain compound SrNi2V2O8 represents a topological system where magnetic degrees of freedom stem from local singlet dimer products on a chain. Topological states only exist at the edges of these chains, i.e. on the surface of the sample. In contrast, Raman light scattering induces topological states different from the Haldane host via interchain spin exchange. These states lead to non-Abelian statistics in close analogy to Kitaev spin liquids.

Resolving the Berezinskii-Kosterlitz-Thouless transition in the two-dimensional XY model with tensor-network-based level spectroscopy

Atsushi Ueda and Masaki Oshikawa

Phys. Rev. B 104, 165132 (2021) - Published 20 October, 2021

The discovery of the Berezinskii-Kosterlitz-Thouless transition some fifty years ago was a subject of the 2016 Nobel Prize in Physics. However, quantitative study of the transition in the two-dimensional XY spin model still suffers from significant finite-size effects. The authors implement the level-spectroscopy method, originally developed for quantum systems. They utilize the modern tensor-network renormalization scheme. This allows for an extremely accurate determination of the critical point as well as for a visualization of the celebrated Kosterlitz renormalization-group flow.

Signatures of the charge density wave collective mode in the infrared optical response of VSe2

Xuanbo Feng (馮翾博), Jans Henke, Corentin Morice, Charles J. Sayers, Enrico Da Como, Jasper van Wezel, and Erik van Heumen

Phys. Rev. B 104, 165134 (2021) - Published 21 October, 2021

The layered transition-metal dichalcogenide VSe2 undergoes a phase transition from a good metal to a charge density wave phase. Recent advances in crystal growth enable a detailed study of the imprint of the charge density wave on the optical conductivity. The authors observe emerging infrared active phonon modes and a mass enhancement of the charge carriers due to the interaction with the lattice. They identify key signatures of the elusive sliding mode associated with the charge order in this material.

Transport in the two-dimensional Fermi-Hubbard model: Lessons from weak coupling

Thomas G. Kiely and Erich J. Mueller

Phys. Rev. B 104, 165143 (2021) - Published 25 October, 2021

Strongly correlated materials, where electron-electron interactions dominate, display a range of important yet poorly understood phenomena including high-temperature superconductivity and exotic magnetism. Many such materials also feature unusual “strange-metal” transport, corresponding to unexpected temperature dependence of the resistivity. The authors show that, due to band-structure nesting and a bounded spectrum, even a weakly interacting system can display resistivity signatures that are typically associated with such strange metals. Their results are particularly important for interpreting recent cold-atom experiments which explore transport in the Fermi Hubbard model.

Magnetic structure of the topological semimetal YbMnSb2

Jian-Rui Soh, Siobhan M. Tobin, Hao Su, Ivica Zivkovic, Bachir Ouladdiaf, Anne Stunault, J. Alberto Rodríguez-Velamazán, Ketty Beauvois, Yanfeng Guo, and Andrew T. Boothroyd

Phys. Rev. B 104, L161103 (2021) - Published 5 October, 2021

Recently, the antiferromagnet YbMnSb2 has been predicted to be a topological semimetal driven by time-reversal symmetry breaking, where the magnetic order is key to its behavior as a topological material. Depending on the magnetic order, YbMnSb2 can have Weyl, nodal-line, or Dirac topological features. In this Letter, the authors use a combination of unpolarized and polarized neutron diffraction to determine unambiguously the magnetic structure of YbMnSb2 and the topology of the electronic bands.

Yang-Lee edge singularity triggered entanglement transition

Shao-Kai Jian, Zhi-Cheng Yang, Zhen Bi, and Xiao Chen

Phys. Rev. B 104, L161107 (2021) - Published 11 October, 2021

The authors demonstrate a mechanism whereby the Yang-Lee edge singularity in certain PT-symmetric non-Hermitian Hamiltonians can trigger a first-order entanglement transition. At the transition, the entanglement entropy of the steady state jumps discontinuously from a volume-law to an area-law scaling. Physically, such non-Hermitian Hamiltonian evolutions arise when post-selecting a particular quantum trajectory of a system subject to continuous weak measurements.

Current-induced second harmonic generation in inversion-symmetric Dirac and Weyl semimetals

Kazuaki Takasan, Takahiro Morimoto, Joseph Orenstein, and Joel E. Moore

Phys. Rev. B 104, L161202 (2021) - Published 5 October, 2021

Topological materials have gained attention as a platform to explore novel nonlinear optical responses. To date, this research has largely focused on acentric materials, leaving the inversion-symmetric systems largely unexplored. In this work, the authors demonstrate that inversion-symmetric topological semimetals show perturbatively divergent second-harmonic generation when a finite current is applied. Because the response is both large and highly controllable, it can be used to investigate the nonequilibrium physics of topological materials and design future optical devices.

Radiative lifetime of free excitons in hexagonal boron nitride

Sébastien Roux, Christophe Arnold, Fulvio Paleari, Lorenzo Sponza, Eli Janzen, James H. Edgar, Bérangère Toury, Catherine Journet, Vincent Garnier, Philippe Steyer, Takashi Taniguchi, Kenji Watanabe, François Ducastelle, Annick Loiseau, and Julien Barjon

Phys. Rev. B 104, L161203 (2021) - Published 27 October, 2021

In a previous PRL, the authors found quantitative evidence that, despite hexagonal boron nitride (h-BN) having an indirect band gap, the luminescence efficiency of high-quality crystals reaches the level of the best direct semiconductors. Here, thanks to breakthrough experiments performed using an original time-resolved cathodoluminescence setup, the authors address the root cause of the high quantum yield luminescence efficiency. These results should have practical application for the use of h-BN in 2D materials based optoelectronic devices.

Homogeneous optical anisotropy in an ensemble of InGaAs quantum dots induced by strong enhancement of the heavy-hole band Landé parameter q

A. V. Trifonov, I. A. Akimov, L. E. Golub, E. L. Ivchenko, I. A. Yugova, A. N. Kosarev, S. E. Scholz, C. Sgroi, A. Ludwig, A. D. Wieck, D. R. Yakovlev, and M. Bayer

Phys. Rev. B 104, L161405 (2021) - Published 18 October, 2021

The authors report on a mechanism of strong enhancement of the band Landé parameter q due to in-plane confinement of holes and the valence-band warping. This explains the surprisingly large in-plane hole g factor in symmetric self-assembled (In,Ga)As/GaAs quantum dots with D2d symmetry as revealed by coherent optical spectroscopy. The proposed mechanism results in uniform magnetic field induced optical anisotropy for the entire quantum dot ensemble, which is a prerequisite for the realization of spin quantum memories and spin-photon entanglement in the ensemble.

Resolving the Berezinskii-Kosterlitz-Thouless transition in the two-dimensional XY model with tensor-network-based level spectroscopy

Phys. Rev. B 104, 165132 (2021) - Published 20 October, 2021

The discovery of the Berezinskii-Kosterlitz-Thouless transition some fifty years ago was a subject of the 2016 Nobel Prize in Physics. However, quantitative study of the transition in the two-dimensional XY spin model still suffers from significant finite-size effects. The authors implement the level-spectroscopy method, originally developed for quantum systems. They utilize the modern tensor-network renormalization scheme. This allows for an extremely accurate determination of the critical point as well as for a visualization of the celebrated Kosterlitz renormalization-group flow.

The layered transition-metal dichalcogenide VSe2 undergoes a phase transition from a good metal to a charge density wave phase. Recent advances in crystal growth enable a detailed study of the imprint of the charge density wave on the optical conductivity. The authors observe emerging infrared active phonon modes and a mass enhancement of the charge carriers due to the interaction with the lattice. They identify key signatures of the elusive sliding mode associated with the charge order in this material.

Transport in the two-dimensional Fermi-Hubbard model: Lessons from weak coupling

Thomas G. Kiely and Erich J. Mueller

Phys. Rev. B 104, 165143 (2021) - Published 25 October, 2021

Strongly correlated materials, where electron-electron interactions dominate, display a range of important yet poorly understood phenomena including high-temperature superconductivity and exotic magnetism. Many such materials also feature unusual “strange-metal” transport, corresponding to unexpected temperature dependence of the resistivity. The authors show that, due to band-structure nesting and a bounded spectrum, even a weakly interacting system can display resistivity signatures that are typically associated with such strange metals. Their results are particularly important for interpreting recent cold-atom experiments which explore transport in the Fermi Hubbard model.
