Output photon statistics in driven dissipative arrays of transmission line resonators — •Robert Jirschik and Michael Hartmann — TU Munich, Munich, Germany

Arrays of circuit cavities offer fascinating perspectives for exploring quantum many body systems in a driven dissipative regime where photon losses are continuously compensated by coherent laser drives. Here we specifically consider a scenario with input lasers of high intensity and thus high intra-resonator excitation numbers. Two different systems which depend on experimentally well controlable properties are considered:

One is a chain of nonlinear transmission line resonators driven by a single input laser, while the other one contains three transmission line resonator sites with a single non-linearity in the middle and lasers with an adjustable phase difference driving the two outer resonator sites. For both set-ups we provide results for the mean photon number and time-resolved second order correlation function of each individual site depending on their different experimental parameters.
