Weyl Semimetal Phase in Noncentrosymmetric Transition-Metal Monophosphides

- H. Weng, C. Fang, Z. Fang, Andrei Bernevig, X. Dai
- Physics
- 31 December 2014

Based on first-principle calculations, we show that a family of nonmagnetic materials including TaAs, TaP, NbAs, and NbP are Weyl semimetals (WSM) without inversion centers. We find twelve pairs of… Expand

Multi-Weyl topological semimetals stabilized by point group symmetry.

- C. Fang, M. Gilbert, X. Dai, B. Bernevig
- Physics, MedicinePhysical review letters
- 30 November 2011

We perform a complete classification of two-band k·p theories at band crossing points in 3D semimetals with n-fold rotation symmetry and broken time-reversal symmetry. Using this classification, we… Expand

Correspondence between Winding Numbers and Skin Modes in Non-Hermitian Systems.

- K. Zhang, Zhesen Yang, C. Fang
- Physics, MedicinePhysical review letters
- 2 October 2019

We establish exact relations between the winding of "energy" (eigenvalue of Hamiltonian) on the complex plane as momentum traverses the Brillouin zone with periodic boundary condition, and the… Expand

Topological nodal line semimetals with and without spin-orbital coupling

lines in the Brillouin zone. We propose two different classes of symmetry protected nodal lines in the absence and in the presence of spin-orbital coupling (SOC), respectively. In the former, we… Expand

Bulk Topological Invariants in Noninteracting Point Group Symmetric Insulators

- C. Fang, M. Gilbert, B. Bernevig
- Physics
- 24 July 2012

We survey various quantized bulk physical observables in two- and three-dimensional topological band insulators invariant under translational symmetry and crystallographic point group symmetries… Expand

Compensated Semimetal LaSb with Unsaturated Magnetoresistance.

By combining angle-resolved photoemission spectroscopy and quantum oscillation measurements, we performed a comprehensive investigation on the electronic structure of LaSb, which exhibits… Expand

Topological Semimetals with Helicoid Surface States
