Dirac States in an Inclined Two-Dimensional Su-Schrieffer-Heeger Model
Chang-An Li, Sang-Jun Choi, Song-Bo Zhang +1
We propose to realize Dirac states in an inclined two-dimensional Su-Schrieffer-Heeger model on a square lattice. We show that a pair of Dirac points protected by space-time invers…
Transition from metal to higher-order topological insulator driven by random flux
Chang-An Li, Song-Bo Zhang, Jan Carl Budich +1
Random flux is commonly believed to be incapable of driving full metal-insulator transitions in non-interacting systems. Here we show that random flux can after all induce a full m…
Intrinsic finite-energy Cooper pairing in superconductors
Masoud Bahari, Song-Bo Zhang, Björn Trauzettel
We show that Cooper pairing can occur intrinsically away from the Fermi surface in superconductors with strong spin-orbit coupling and equally curved bands in the normal st…
Intertwined Weyl phases emergent from higher-order topology and unconventional Weyl fermions via crystalline symmetry
W. B. Rui, Zhen Zheng, Moritz M. Hirschmann +3
We discover three-dimensional intertwined Weyl phases, by developing a theory to create topological phases. The theory is based on intertwining existing topological gapped and gapl…
Super-resonant transport of topological surface states subjected to in-plane magnetic fields
Song-Bo Zhang, Chang-An Li, Francisco Peña-Benitez +4
Magnetic oscillations of Dirac surface states of topological insulators are expected to be associated with the formation of Landau levels or the Aharonov-Bohm effect. We instead st…
Higher-order Fabry-Pérot Interferometer from Topological Hinge States
Chang-An Li, Song-Bo Zhang, Jian Li +1
We propose an intrinsic 3D Fabry-Pérot type interferometer, coined "higher-order interferometer", that utilizes the chiral hinge states of second-order topological insulators and c…
