Interaction effects in a multi-channel Fabry-P\'erot interferometer in the Aharonov-Bohm regime

摘要: We investigate a Fabry-Perot interferometer in the integer Hall regime which only one edge channel is transmitted and n channels are trapped into loop. Addressing recent experimental observations, we assume that Coulomb blockade effects completely suppressed due to screening, while keeping track of residual strong short range electron-electron interaction between co-propagating This kind can be described framework edge-magnetoplasmon scattering matrix theory allowing us evaluate backscattering current associated differential conductance as function bias voltage. The remarkable features these quantities discussed number channels. developed formalism reveals very general provides also simple way model experimentally relevant geometry some absorbed an Ohmic contact, leading energy dissipation.
