Quantum correlations in the 1-D driven dissipative transverse field XY model
Chaitanya Joshi, Felix Nissen, Jonathan Keeling
We study the non-equilibrium steady state (NESS) of a driven dissipative one-dimensional system near a critical point, and explore how the quantum correlations compare to the known…
Collective Suppression of Linewidths in Circuit QED
Felix Nissen, Johannes M. Fink, Jonas A. Mlynek +2
We report the experimental observation, and a theoretical explanation, of collective suppression of linewidths for multiple superconducting qubits coupled to a good cavity. This de…
Disordered driven coupled cavity arrays: Non-equilibrium stochastic mean-field theory
Gytis Kulaitis, Frank Krüger, Felix Nissen +1
We study the interplay of disorder with pumping and decay in coupled qubit-cavity arrays, the Jaynes-Cummings-Hubbard model. We find that relatively weak disorder can wash out the…
Non-equilibrium dynamics of coupled qubit-cavity arrays
Felix Nissen, Sebastian Schmidt, Matteo Biondi +3
We study the coherence and fluorescence properties of the coherently pumped and dissipative Jaynes-Cummings-Hubbard model describing polaritons in a coupled-cavity array. At weak h…
WKB approach and quantum corrections to classical dynamics in the Josephson problem
Felix Nissen, Jonathan Keeling
We apply a many-body Wentzel-Kramers-Brillouin (WKB) approach to determine the leading quantum corrections to the semiclassical dynamics of the Josephson model, describing interact…
