A gap-protected zero-Hall effect state in the quantum limit of the nonsymmorphic metal KHgSb
Sihang Liang, Satya Kushwaha, Tong Gao +8
A recurring theme in topological matter is the protection of unusual electronic states by symmetry, for example, protection of the surface states in Z2 topological insulators by ti…
Topological phases in the TaSe3 compound
Simin Nie, Lingyi Xing, Rongying Jin +3
Based on first-principles calculations, we show that stoichiometric TaSe3, synthesized in space group P21/m, belongs to a three-dimensional (3D) strong topological insulator (TI) p…
Multiple topological states in iron-based superconductors
Peng Zhang, Zhijun Wang, Xianxin Wu +24
Topological insulators and semimetals as well as unconventional iron-based superconductors have attracted major recent attention in condensed matter physics. Previously, however, l…
All "Magic Angles" Are "Stable" Topological
Zhida Song, Zhijun Wang, Wujun Shi +3
We show that the electronic structure of the low-energy bands in the small angle-twisted bilayer graphene consists of a series of semi-metallic and topological phases. In particula…
Disconnected Elementary Band Representations, Fragile Topology, and Wilson Loops as Topological Indices: An Example on the Triangular Lattice
Barry Bradlyn, Zhijun Wang, Jennifer Cano +1
In this work, we examine the topological phases that can arise in triangular lattices with disconnected elementary band representations. We show that, although these phases may be…
Twisted Bilayer Graphene: A Phonon Driven Superconductor
Biao Lian, Zhijun Wang, B. Andrei Bernevig
We study the electron-phonon coupling in twisted bilayer graphene (TBG), which was recently experimentally observed to exhibit superconductivity around the magic twist angle $θ\app…
Higher-Order Topology, Monopole Nodal Lines, and the Origin of Large Fermi Arcs in Transition Metal Dichalcogenides XTe (X=Mo,W)
Zhijun Wang, Benjamin J. Wieder, Jian Li +2
In recent years, transition metal dichalcogenides (TMDs) have garnered great interest as topological materials -- monolayers of centrosymmetric -phase TMDs have been identified…
Topological Dirac semimetal phase in the iron-based superconductor Fe(Te,Se)
Peng Zhang, Zhijun Wang, Yukiaki Ishida +20
Topological Dirac semimetals (TDSs) exhibit bulk Dirac cones protected by time reversal and crystal symmetry, as well as surface states originating from non-trivial topology. While…
Higher-Order Topology in Bismuth
Frank Schindler, Zhijun Wang, Maia G. Vergniory +12
The mathematical field of topology has become a framework to describe the low-energy electronic structure of crystalline solids. A typical feature of a bulk insulating three-dimens…
