Spontaneous Chiral Symmetry Breaking in Bilayer Graphene
Fan Zhang
Bilayer graphene and its thicker cousins with Rhombohedral stacking have attracted considerable attention because of their susceptibility to a variety of broken chiral symmetry sta…
Observation of Valley Zeeman and Quantum Hall Effects at Q Valley of Few-Layer Transition Metal Disulfides
Zefei Wu, Shuigang Xu, Huanhuan Lu +10
In few-layer (FL) transition metal dichalcogenides (TMDC), the conduction bands along the Gamma-K directions shift downward energetically in the presence of interlayer interactions…
Weak Topological Insulators and Composite Weyl Semimetals: -BiX (X=Br, I)
Cheng-Cheng Liu, Jin-Jian Zhou, Yugui Yao +1
While strong topological insulators (STI) have been experimentally realized soon after their theoretical predictions, a weak topological insulator (WTI) has yet to be unambiguously…
SU(3) Quantum Hall Ferromagnetism in SnTe
Xiao Li, Fan Zhang, A. H. MacDonald
The (111) surface of SnTe hosts one isotropic -centered and three degenerate anisotropic - centered Dirac surface states. We predict that a nematic phase with spont…
Possible Superconductivity Approaching Ice Point
Yanfeng Ge, Fan Zhang, Yugui Yao
Recently BCS superconductivity at 203 K has been discovery in a highly compressed hydrogen sulfide. We use first-principles calculations to systematically examine the effects of pa…
Spin-orbit-free Weyl-loop and Weyl-point semimetals in a stable three-dimensional carbon allotrope
Yuanping Chen, Yuee Xie, Shengyuan A. Yang +4
Topological band theory has revolutionized our understanding of electronic structure of materials, in particular, a novel state - Weyl semimetal - has been predicted for systems wi…
Chirality Hall Effect in Weyl Semimetals
Shengyuan A. Yang, Hui Pan, Fan Zhang
We generalize a semiclassical theory and use the argument of angular momentum conservation to examine the ballistic transport in lightly-doped Weyl semimetals, taking into account…
Universal low-temperature Ohmic contacts for quantum transport in transition metal dichalcogenides
Shuigang Xu, Zefei Wu, Huanhuan Lu +14
Low carrier mobility and high electrical contact resistance are two major obstacles prohibiting explorations of quantum transport in TMDCs. Here, we demonstrate an effective method…
