Surface states and Rashba-type spin polarization in antiferromagnetic MnBi2Te4(0001)

R. C. Vidal et al.

Phys. Rev. B 100, 121104(R) (2019) - Published 11 September, 2019

The layered van der Waals antiferromagnet MnBi2Te4 has been predicted previously to realize the first intrinsic magnetic topological insulator. Here, the authors report spin- and angle-resolved photoemission experiments for the MnBi2Te4(0001) surface, revealing a surface state in the bulk band gap and providing evidence for the interplay between magnetic exchange interaction and spin-orbit coupling in the surface electronic structure. MnBi2Te4 thus constitutes a promising candidate to exploit the interplay of topological states and magnetic order in spintronic device concepts.

Imaging propagative exciton polaritons in atomically thin WSe2 waveguides

F. Hu, Y. Luan, J. Speltz, D. Zhong, C. H. Liu, J. Yan, D. G. Mandrus, X. Xu, and Z. Fei

Phys. Rev. B 100, 121301(R) (2019) - Published 4 September, 2019

This work reports a nano-optical imaging study of the transverse-electric exciton polaritons in atomically thin WSe2 nanoflakes by using a scattering-type scanning near-field optical microscope excited by an s-polarized laser. These exciton polaritons demonstrate the signature back-bending polariton dispersion, a long propagation length, and a tailored polariton wavelength by controlling the thickness of WSe2. The discovery of long-propagating exciton polaritons in WSe2 atomic layers paves the way for the future development of actively tunable polaritonic devices in the near-infrared region.

Origin of the butterfly magnetoresistance in a Dirac nodal-line system

Y.-C. Chiu, K.-W. Chen, R. Schönemann, V. L. Quito, S. Sur, Q. Zhou, D. Graf, E. Kampert, T. Förster, K. Yang, G. T. McCandless, Julia Y. Chan, R. E. Baumbach, M. D. Johannes, and L. Balicas

Phys. Rev. B 100, 125112 (2019) - Published 4 September, 2019

ZrSiSe, similar to ZrSiS and ZrSiTe, displays a set of Dirac nodal lines at nonsymmorphic (and symmorphic) positions that are (are not) protected from gap opening due to spin-orbit coupling. The fourfold angular dependence of its magnetoresistivity was recently claimed to result from a topological phase transition as a function of field orientation. Instead, the calculations here reveal that this compound does not display a (strong) topological character, while the measurements here indicate that this anomalous magnetoresistivity results from the angular dependence of its quasiparticle quantum lifetime(s).

Emergent symmetry and conserved current at a one-dimensional incarnation of deconfined quantum critical point

Rui-Zhen Huang, Da-Chuan Lu, Yi-Zhuang You, Zi Yang Meng, and Tao Xiang

Phys. Rev. B 100, 125137 (2019) - Published 17 September, 2019

Although great efforts have been expended on the deconfined quantum critical point (DQCP) for 2D systems, ambiguities are still not completely clarified. Here, the authors focus on a recently proposed 1D incarnation of DQCP in a spin-½ chain. Using the variational matrix product state, a continuous transition between a valence-bond solid phase and a ferromagnetic phase is discovered. Two emergent O(2) symmetries together with the associated conserved current operators are revealed and in perfect agreement with the controlled field theory predictions.

Growth of nematic susceptibility in the field-induced normal state of an iron-based superconductor revealed by elastoresistivity measurements in a 65 T pulsed magnet

J. A. W. Straquadine, J. C. Palmstrom, P. Walmsley, A. T. Hristov, F. Weickert, F. F. Balakirev, M. Jaime, R. McDonald, and I. R. Fisher

Phys. Rev. B 100, 125147 (2019) - Published 23 September, 2019

In iron-based superconductors, questions surrounding a putative nematic quantum critical point motivate study of the nematic susceptibility at low temperatures. By suppressing superconductivity with pulsed magnetic fields, this work extends the range of elastoresistivity measurements in nearly optimally doped Ba(CoxFe1−x)2As2 an order of magnitude lower in temperature. The authors show that the nematic susceptibility in the field-induced normal state grows monotonically as temperature decreases. This is consistent with the existence of a nearby quantum critical point with nematic character.

Electronic band structure of a two-dimensional oxide quasicrystal

Cheng-Tien Chiang, Martin Ellguth, Florian O. Schumann, Christian Tusche, Richard Kraska, Stefan Förster, and Wolf Widdra

Phys. Rev. B 100, 125149 (2019) - Published 23 September, 2019

Since the discovery of quasicrystals, the study of their electronic structure has been a challenging topic due to the absence of translational symmetry. Here, the valence bands of a novel two-dimensional ultrathin BaTiO3-derived oxide quasicrystal are determined by momentum-resolved photoelectron spectroscopy. The dispersion of the oxygen 2p bands and the occupation of the Ti 3d states are identified. They bridge the knowledge deriving from free-electron-like wave functions in bulk quasicrystals to that of the more localized electrons in confined dimensions.

Fractonic matter in symmetry-enriched U(1) gauge theory

Dominic J. Williamson, Zhen Bi, and Meng Cheng

Phys. Rev. B 100, 125150 (2019) - Published 23 September, 2019

This study reveals the relation between symmetry restrictions on the mobility of quasiparticles and symmetry-enriched topological order, where the actions of translation and global symmetries on quasiparticle excitations do not commute. The approach is demonstrably fruitful as one can systematically classify U(1) gauge theories enriched by translation and certain global symmetry and identify new examples of fractonic matter. It is conjectured that all such theories can be constructed by gauging layered symmetry-protected topological phases.

Magnetoelectric control of topological phases in graphene

Hiroyuki Takenaka, Shane Sandhoefner, Alexey A. Kovalev, and Evgeny Y. Tsymbal

Phys. Rev. B 100, 125156 (2019) - Published 25 September, 2019

A new paradigm for voltage controlled topological antiferromagnetic spintronics is envisioned via proximity of a magnetoelectric antiferromagnet to a two-dimensional material. Using graphene/chromia as a model system, the authors predict the emergence of unconventional anomalous Hall effects that are electrically controlled by the Néel vector as well as the appearance and transformation of different topological phases and the emergence of chiral edge states. The results advance the research field of topological phenomena and establish connection between the subfields of antiferromagnetism, magnetoelectricity, topology, spintronics, and valleytronics.

Kondo effect due to a hydrogen impurity in graphene: A multichannel Kondo problem with diverging hybridization

Zheng Shi, Emilian M. Nica, and Ian Affleck

Phys. Rev. B 100, 125158 (2019) - Published 25 September, 2019

Magnetic impurities in conducting media are often Kondo screened by conduction electrons. However, for hydrogen impurities in graphene, which also induce magnetic moments, the picture is complicated by the energy-dependent, unusually enhanced local density of states. Here, the authors study the Kondo effect in this system, which is intimately related to the Kondo problem of three impurity spins on an equilateral triangle in a metallic host. The induced magnetic moment is found to be underscreened for local potential scattering that is not too strong, leaving a residual spin of ½.

Optical excitation of magnons in an easy-plane antiferromagnet: Application to Sr2IrO4

Urban F. P. Seifert and Leon Balents

Phys. Rev. B 100, 125161 (2019) - Published 27 September, 2019

Probing and controlling the dynamics of quantum materials is a growing theme in condensed matter physics. In recent experiments on Mott-insulating antiferromagnets, the excitation of low-energy magnons via an ultrafast subgap laser beam has been demonstrated, implying a direct coupling of the light field to spin excitations. Here, the authors develop a quantum theory for this “Inverse Faraday effect”, with the specific example of the spin-orbit Mott insulator Sr2IrO4 in mind. Their formalism determines the effect’s dependence on the frequency and polarization of the pump laser, revealing a tight relationship to the two-magnon density of states.

Effective dynamics of two-dimensional Bloch electrons in external fields derived from symmetry

E. A. Fajardo and R. Winkler

Phys. Rev. B 100, 125301 (2019) - Published 3 September, 2019

Symmetry is a powerful tool for understanding the dynamics of Bloch electrons in a crystal. Here, the authors develop a general theory to characterize the symmetry of Bloch electrons in a tight-binding description, focusing in particular on the possibility that the symmetry labels called irreducible representations are not always unique, although this does not affect observable physics. The theory is used to construct a generic effective Hamiltonian for electrons in monolayer MoS2, which incorporates spin-orbit coupling, strain, and external electric and magnetic fields.

Although great efforts have been expended on the deconfined quantum critical point (DQCP) for 2D systems, ambiguities are still not completely clarified. Here, the authors focus on a recently proposed 1D incarnation of DQCP in a spin-½ chain. Using the variational matrix product state, a continuous transition between a valence-bond solid phase and a ferromagnetic phase is discovered. Two emergent O(2) symmetries together with the associated conserved current operators are revealed and in perfect agreement with the controlled field theory predictions.

Growth of nematic susceptibility in the field-induced normal state of an iron-based superconductor revealed by elastoresistivity measurements in a 65 T pulsed magnet

Phys. Rev. B 100, 125147 (2019) - Published 23 September, 2019

In iron-based superconductors, questions surrounding a putative nematic quantum critical point motivate study of the nematic susceptibility at low temperatures. By suppressing superconductivity with pulsed magnetic fields, this work extends the range of elastoresistivity measurements in nearly optimally doped Ba(CoxFe1−x)2As2 an order of magnitude lower in temperature. The authors show that the nematic susceptibility in the field-induced normal state grows monotonically as temperature decreases. This is consistent with the existence of a nearby quantum critical point with nematic character.

Electronic band structure of a two-dimensional oxide quasicrystal

Phys. Rev. B 100, 125149 (2019) - Published 23 September, 2019

Since the discovery of quasicrystals, the study of their electronic structure has been a challenging topic due to the absence of translational symmetry. Here, the valence bands of a novel two-dimensional ultrathin BaTiO3-derived oxide quasicrystal are determined by momentum-resolved photoelectron spectroscopy. The dispersion of the oxygen 2p bands and the occupation of the Ti 3d states are identified. They bridge the knowledge deriving from free-electron-like wave functions in bulk quasicrystals to that of the more localized electrons in confined dimensions.

Fractonic matter in symmetry-enriched U(1) gauge theory

Dominic J. Williamson, Zhen Bi, and Meng Cheng

Phys. Rev. B 100, 125150 (2019) - Published 23 September, 2019

This study reveals the relation between symmetry restrictions on the mobility of quasiparticles and symmetry-enriched topological order, where the actions of translation and global symmetries on quasiparticle excitations do not commute. The approach is demonstrably fruitful as one can systematically classify U(1) gauge theories enriched by translation and certain global symmetry and identify new examples of fractonic matter. It is conjectured that all such theories can be constructed by gauging layered symmetry-protected topological phases.

A new paradigm for voltage controlled topological antiferromagnetic spintronics is envisioned via proximity of a magnetoelectric antiferromagnet to a two-dimensional material. Using graphene/chromia as a model system, the authors predict the emergence of unconventional anomalous Hall effects that are electrically controlled by the Néel vector as well as the appearance and transformation of different topological phases and the emergence of chiral edge states. The results advance the research field of topological phenomena and establish connection between the subfields of antiferromagnetism, magnetoelectricity, topology, spintronics, and valleytronics.

Kondo effect due to a hydrogen impurity in graphene: A multichannel Kondo problem with diverging hybridization

Zheng Shi, Emilian M. Nica, and Ian Affleck

Phys. Rev. B 100, 125158 (2019) - Published 25 September, 2019

Magnetic impurities in conducting media are often Kondo screened by conduction electrons. However, for hydrogen impurities in graphene, which also induce magnetic moments, the picture is complicated by the energy-dependent, unusually enhanced local density of states. Here, the authors study the Kondo effect in this system, which is intimately related to the Kondo problem of three impurity spins on an equilateral triangle in a metallic host. The induced magnetic moment is found to be underscreened for local potential scattering that is not too strong, leaving a residual spin of ½.

Phys. Rev. B 100, 125161 (2019) - Published 27 September, 2019

Probing and controlling the dynamics of quantum materials is a growing theme in condensed matter physics. In recent experiments on Mott-insulating antiferromagnets, the excitation of low-energy magnons via an ultrafast subgap laser beam has been demonstrated, implying a direct coupling of the light field to spin excitations. Here, the authors develop a quantum theory for this “Inverse Faraday effect”, with the specific example of the spin-orbit Mott insulator Sr2IrO4 in mind. Their formalism determines the effect’s dependence on the frequency and polarization of the pump laser, revealing a tight relationship to the two-magnon density of states.

Phys. Rev. B 100, 125301 (2019) - Published 3 September, 2019

Symmetry is a powerful tool for understanding the dynamics of Bloch electrons in a crystal. Here, the authors develop a general theory to characterize the symmetry of Bloch electrons in a tight-binding description, focusing in particular on the possibility that the symmetry labels called irreducible representations are not always unique, although this does not affect observable physics. The theory is used to construct a generic effective Hamiltonian for electrons in monolayer MoS2, which incorporates spin-orbit coupling, strain, and external electric and magnetic fields.
