Light Induced Electron Superconductivity with Driven Optical Cavity — •Ahana Chakraborty and Francesco Piazza — Max Planck Institute for Physics of Complex Systems, Dresden, Germany

In a recent work, Schlawin et. al. [PRL, 122, 133602 (2019)] studied the possibility to induce superconductivity via cavity-mediated electron-electron interactions. This cavity-induced 'Amperean' pairing, which involves electrons propagating in the same direction, with total centre-of-mass momentum on the Fermi surface is estimated to lead to superconductivity in the low kelvin-regime for GaAs using realistic cavity parameters. In our work, we investigate the possibility of stabilising the superconducting state at even higher temperatures by driving the optical cavity. The effect of loss of photons as well as incoherent pump is incorporated by non- equilibrium field theoretic techniques, which also allow us to explore beyond the weak coupling regime of the electrons and the cavity.
