@article{Menon2018PhotoinducedTA, title={Photoinduced tunable anomalous Hall and Nernst effects in tilted Weyl semimetals using Floquet theory}, author={Anirudha Menon and Debashree Chowdhury and Banasri Basu}, journal={Physical Review B}, year={2018}, volume={98}, pages={205109} }

In this paper, we discuss the effect of a periodically driving circularly polarized laser beam in the high-frequency limit, on the band structure and thermal transport properties of type-I and type-II Weyl semimetals (WSMs). We develop the notion of an effective Fermi surface stemming from the time-averaged Floquet Hamiltonian and discuss its effects on the steady-state occupation numbers of electrons and holes in the linearized model. In order to compute the transport coefficients averaged…
