Persistent current induced by quantum light cond-mat.mes-hall cond-mat.supr-con It is demonstrated that the strong coupling of an electron gas to photons in systems with broken time-reversal symmetry results in bound electron-photon states which cannot be backscattered elastically. As a consequence, the electron ga...
