Quantum Properties of the radiation emitted by a conductor in the Coulomb Blockade Regime
arXiv:1512.05812 · doi:10.1103/PhysRevB.95.125311
Abstract
We present an input-output formalism describing a tunnel junction strongly coupled to its electromagnetic environment. We exploit it in order to investigate the dynamics of the radiation being emitted and scattered by the junction. We find that the non-linearity imprinted in the electronic transport by a properly designed environment generates strongly squeezed radiation. Our results show that the interaction between a quantum conductor and electromagnetic fields can be exploited as a resource to design simple sources of non-classical radiation.
