Description:
Author(s): Juha Leppäkangas, Mikael Fogelström, Michael Marthaler, and Göran Johansson Using a perturbation expansion to the fourth order in a junction critical current, the authors study the generation of nonclassical microwave radiation by inelastic Cooper pair tunneling in a small voltage-biased Josephson junction connected to a superconducting transmission line. The second order in the tunneling current only allows consideration of independent events. Pushing the calculation to the fourth order allows capture of the temporal correlations in the charge transport and their connection to the ones in the emitted electromagnetic radiation. [Phys. Rev.
