Abstract
Amperean superconductivity is stemming from attractive effective electron-electron interactions mediated by a transverse gauge field. Amperean superconductivity has been recently proposed to occur at temperatures on the order of 1 K in two-dimensional electron gases embedded inside deep subwavelength optical cavities. Here, the authors generalize the microscopic theory of cavity-induced Amperean superconductivity to the case of graphene and then argue that this superconducting state cannot be achieved in the deep subwavelength regime.
