Photocurrents in Weyl semimetals
Ching-Kit Chan, Netanel H. Lindner, Gil Refael +1
The generation of photocurrent in an ideal two-dimensional Dirac spectrum is symmetry-forbidden. In sharp contrast, we show that three-dimensional Weyl semimetals can generically s…
Type-II Weyl cone transitions in driven semimetals
Ching-Kit Chan, Yun-Tak Oh, Jung Hoon Han +1
Periodically driven systems provide tunable platforms to realize interesting Floquet topological phases and phase transitions. In electronic systems with Weyl dispersions, the band…
Adiabatic Green's function technique and the transient behavior in time-dependent fermion-boson coupled models
Yun-Tak Oh, Yoichi Higashi, Ching-Kit Chan +1
The Lang-Firsov Hamiltonian, a well-known solvable model of interacting fermion-boson system with sideband features in the fermion spectral weight, is generalized to have the time-…
