DOI: 10.1016/j.aop.2018.04.018
Abstract: We present a new theory of photoemission for Weyl semimetals. We derive this theory using a model with a boundary surface at $z=0$. Due to the boundary, the self adjoint condition needs to be verified… read more here.

DOI: 10.1021/acs.nanolett.9b05179
Abstract: Objects around us constantly emit and absorb thermal radiation. The emission and absorption processes are governed by two fundamental radiative properties: emissivity and absorptivity. For reciprocal systems, the emissivity and absorptivity are restricted to be… read more here.

Abstract: We theoretically investigate the transport in a magnetic/normal/magetic hybrid structure on the surface of a Weyl semimetal. We find a directional-dependent tunneling which is sensitive to the magnetic field configuration and the electric gate voltage.… read more here.

DOI: 10.1063/1.5142216
Abstract: Magnetic susceptibility of Weyl semimetals, placed in a tilted magnetic field, is studied. Weyl semimetals have three contributions: spin, orbital, and spin–orbital; all three contributions are investigated for a tilted magnetic field. We find that… read more here.

DOI: 10.1103/physrevb.100.085406
Abstract: Berry curvature acts analogously to a magnetic field in the momentum space, and it modifies the flow of charge carriers and entropy. This induces several intriguing magnetoelectric and magnetothermal transport phenomena in Weyl semimetals. Here,… read more here.
