17. O.V. Kibis Nondissipative electron transport in photon-dressed nanostructures Summary It is shown that the electron coupling to photons in field-dressed nanostructures can result in the ground electron-photon state with a nonzero electric current. Since the current is associated with the ground state, it flows without the Joule heating of the nanostructure and is nondissipative. Such a dissipationless electron transport can be realized in strongly coupled electron-photon systems with the broken time-reversal symmetry — particularly, in quantum rings and chiral nanostructures dressed by circularly polarized photons.
