Topological exceptional surfaces in non-Hermitian systems with parity-time and parity-particle-hole symmetries

Ryo Okugawa and Takehito Yokoyama

Phys. Rev. B 99, 041202(R) (2019) - Published 24 January, 2019

Non-Hermiticity makes possible novel topological phenomena, which are notallowed in Hermitian systems. The authors show that topologically nontrivial band degeneracies can appear as exceptional surfaces in non-Hermitian systems with parity–time and parity–particle-hole symmetries. It is shown that when parity–time or parity–particle-hole symmetry is present, d-dimensional non-Hermitian systems can have (d1)-dimensional exceptional surfaces. This work suggests new topological phases with nodal band structures protected by non-Hermitian topology and symmetry.

Higher-order topological phases: A general principle of construction

Dumitru Călugăru, Vladimir Juričić, and Bitan Roy

Phys. Rev. B 99, 041301(R) (2019) - Published 4 January, 2019

The surface states of a d-dimensional conventional or first-order topological state of matter reside on a (d-1) dimensional boundary. However, its nth order incarnation, commonly known as a higher-order topological (HOT) phase, accommodates (d-n) dimensional boundary states, with corner and hinge modes standing as their representatives. Here, the authors introduce a general principle of systematically constructing the hierarchy of HOT phases by exploiting the symmetry of the system and the corresponding Clifford algebra. This procedure is applicable for insulating as well as gapless phases, and paves the route toward realizing a fourth-order nodal-loop semimetal, devoid of any surface bound state.

Phenomenological theory of heat transport in the fractional quantum Hall effect

Amit Aharon-Steinberg, Yuval Oreg, and Ady Stern

Phys. Rev. B 99, 041302(R) (2019) - Published 8 January, 2019

Experimental evidence shows that thermal transport in fractional quantum Hall (FQH) states involves energy loss to external degrees of freedom. However, so far, theory has disregarded this loss. Here, the authors construct and solve a phenomenological theory for heat transport in FQH states in the presence of these losses. The authors show that in contrast to the electric Hall conductance, the thermal Hall conductance is sensitive to this loss. They find the conditions for experimental extraction of the universal thermal Hall conductance for a FQH state, and the way this value quantitatively changes when the energy losses are not negligible.

Phys. Rev. B 99, 041402(R) (2019) - Published 7 January, 2019

The study of two-dimensional materials has seen a huge surge following the advances made in graphene to isolate single atomic layers. Now the focus is on adding functionality, such as magnetism, into the mix to give us a powerful toolbox of 2D materials we can stack and combine in powerful ways. However, we are currently limited by a lack of diversity in the available materials. Here, the authors introduce a new tool to the collection: VI3 - a hard van der Waals ferromagnet.

Symmetry-protected nodal phases in non-Hermitian systems

Jan Carl Budich, Johan Carlström, Flore K. Kunst, and Emil J. Bergholtz

Phys. Rev. B 99, 041406(R) (2019) - Published 24 January, 2019

Symmetry plays a paramount role for the classification of phases of matter occurring in nature. Combining symmetry analysis with concepts from topology that allow us to identify global and robust physical properties, new phases of quantum matter, such as topological insulators and semimetals, have been discovered in recent years. Here, the authors analyze in general and exemplify the importance of symmetries to the dissipative counterparts of topological semimetals in non-Hermitian systems, thus introducing the notion of symmetry-protected non-Hermitian nodal phases.

Finite-temperature auxiliary-field quantum Monte Carlo: Self-consistent constraint and systematic approach to low temperatures

Yuan-Yao He, Mingpu Qin, Hao Shi, Zhong-Yi Lu, and Shiwei Zhang

Phys. Rev. B 99, 045108 (2019) - Published 3 January, 2019

Ab initio computations of finite-temperature properties are important in fermion systems such as correlated models, ultracold Fermi atomic gases, and optical lattices, and realistic materials. Here, the authors present a highly accurate approach that eliminates the sign problem in standard determinantal quantum Monte Carlo (DQMC) using a gauge constraint in auxiliary-field space. The constraint can be systematically improved by a self-consistent procedure coupling the many-body computation with an independent-particle calculation. A benchmark is performed in the Hubbard model across the entire temperature range.

Hall effect study of the κ-(ET)2X family: Evidence for Mott-Anderson localization

M. Čulo, E. Tafra, B. Mihaljević, M. Basletić, M. Kuveždić, T. Ivek, A. Hamzić, S. Tomić, T. Hiramatsu, Y. Yoshida, G. Saito, J. A. Schlueter, M. Dressel, and B. Korin-Hamzić

Phys. Rev. B 99, 045114 (2019) - Published 8 January, 2019

Mott-Anderson localization is a very important but poorly explored phenomenon within condensed matter physics. Here, the authors present a Hall effect study of the κ-(ET)2X family, where X = Cu2(CN)3, Ag2(CN)3 and B(CN)4, which is ideal for studying the Mott-Anderson localization because correlations and disorder strengths vary with X. The results enable the determination of the proximity of the selected materials to the metal-insulator transition; in that way, one can locate them in the Mott-Anderson phase diagram.

Disconnected elementary band representations, fragile topology, and Wilson loops as topological indices: An example on the triangular lattice

Barry Bradlyn, Zhijun Wang, Jennifer Cano, and B. Andrei Bernevig

Phys. Rev. B 99, 045140 (2019) - Published 25 January, 2019

Like all topologically nontrivial bands, the recently discovered fragile topological states cannot be described with symmetric localized basis functions. Unlike the well-understood “stable” topological phases, fragile ones have a localized description in the presence of additional trivial orbitals. Here, the authors explore the properties of fragile topological bands, focusing on a family of models on a triangular lattice. The authors show how nonabelian Berry phases can be used to diagnose fragile topology. They also explore how fragile topology manifests itself in the entanglement spectrum.

Spin stiffness and domain walls in Dirac-electron mediated magnets

Sahinur Reja, H. A. Fertig, and L. Brey

Phys. Rev. B 99, 045427 (2019) - Published 18 January, 2019

Gapless two-dimensional Dirac electrons are realized in a large variety of contexts, including graphene and topological-insulator surfaces. For many such systems considerable effort has been put into exploiting them to couple magnetic moments - magnetic impurities or moment-carrying crystal defects - to endow the system with magnetic properties. In this work, the authors show that such magnets generically support an emergent long-range interaction, realized in the spin stiffness of the resulting magnet, with remarkable consequences for domain-wall excitations.

Field-induced insulating states in a graphene superlattice

S. Pezzini, S. Wiedmann, A. Mishchenko, M. Holwill, R. Gorbachev, D. Ghazaryan, K. S. Novoselov, and U. Zeitler

Phys. Rev. B 99, 045440 (2019) - Published 29 January, 2019

When graphene is aligned on top of hBN and subjected to a magnetic field, ‘cloning’ of Dirac fermions takes place each time rational values of flux quanta thread the superlattice unit cell. Here, the authors use high-field magnetotransport up to 35 T to address the emergence of insulating replica states in a 15-nm graphene/hBN superlattice. An analysis in the framework of Landau quantization of the replica particles in an effective magnetic field allows us to determine their energy-momentum dispersion, which is renormalized compared with the original electron states.

Like all topologically nontrivial bands, the recently discovered fragile topological states cannot be described with symmetric localized basis functions. Unlike the well-understood “stable” topological phases, fragile ones have a localized description in the presence of additional trivial orbitals. Here, the authors explore the properties of fragile topological bands, focusing on a family of models on a triangular lattice. The authors show how nonabelian Berry phases can be used to diagnose fragile topology. They also explore how fragile topology manifests itself in the entanglement spectrum.

Gapless two-dimensional Dirac electrons are realized in a large variety of contexts, including graphene and topological-insulator surfaces. For many such systems considerable effort has been put into exploiting them to couple magnetic moments - magnetic impurities or moment-carrying crystal defects - to endow the system with magnetic properties. In this work, the authors show that such magnets generically support an emergent long-range interaction, realized in the spin stiffness of the resulting magnet, with remarkable consequences for domain-wall excitations.

When graphene is aligned on top of hBN and subjected to a magnetic field, ‘cloning’ of Dirac fermions takes place each time rational values of flux quanta thread the superlattice unit cell. Here, the authors use high-field magnetotransport up to 35 T to address the emergence of insulating replica states in a 15-nm graphene/hBN superlattice. An analysis in the framework of Landau quantization of the replica particles in an effective magnetic field allows us to determine their energy-momentum dispersion, which is renormalized compared with the original electron states.
