摘要/Abstract

摘要： The influence of the off-resonant circularly polarized light on the Josephson current in the time-reversal broken superconducting Weyl semimetal junctions is investigated by using the Bogoliubov-de Gennes equation and the transfer matrix approach. Both the zero momentum BCS pairing states and the finite momentum Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) pairing states are considered for the Weyl superconductors. When a circularly polarized light is applied, it is shown that the current phase relation remains unchanged for the BCS pairing with the increasing of incident radiation intensity A₀. For FFLO pairing, the Josephson current exhibits the 0-π transition and periodic oscillation as a function of A₀. The dependence of free energy and critical current on A₀ are also investigated.
