@article{Zhang2022FloquetWeylSG, title={Floquet-Weyl semimetals generated by an optically resonant interband transition}, author={Runnan Zhang and Ken-ichi Hino and Nobuya Maeshima}, journal={Physical Review B}, year={2022} }

Floquet-Weyl semimetals (FWSMs) generated by irradiation of a continuous-wave laser with left-hand circular polarization (rotating in counterclockwise sense with time) on the group II-V narrow gap semiconductor Zn 3 As 2 are theoretically investigated, where the frequency of the laser is set nearly resonant with a band gap of the crystal. It is found that the excitation of the crystal by such a laser induce two types of FWSM phases that diﬀer absolutely in characters. To be speciﬁc, the…
