Protection of quantum information in a chain of Josephson junctions
Paul Brookes, Tikai Chang, Marzena Szymanska +3
Symmetry considerations are key towards our understanding of the fundamental laws of Nature. The presence of a symmetry implies that a physical system is invariant under specific t…
Condensation in hybrid superconducting cavity-microscopic spins systems with finite-bandwidth drive
R. Au-Yeung, M. H. Szymanska, E. Ginossar
Using Keldysh field theory, we find conditions for non-equilibrium condensation in the open Tavis-Cummings model under a direct finite-bandwidth incoherent cavity drive. Experiment…
Critical slowing down in the bistable regime of circuit quantum electrodynamics
P. Brookes, G. Tancredi, A. D. Patterson +5
We investigate the dynamics of the bistable regime of the generalized Jaynes-Cummings Hamiltonian (GJC), realised by a circuit quantum electrodynamics (cQED) system consisting of a…
Driven Bose-Hubbard dimer under nonlocal dissipation: A bistable time crystal
Cristóbal Lledó, Themistoklis Mavrogordatos, Marzena Szymańska
We investigate the critical behavior of the open coherently-driven Bose-Hubbard dimer under nonlocal dissipation. A conserved quantity arises from the nonlocal nature of the dissip…
Rare quantum metastable states in the strongly dispersive Jaynes-Cummings oscillator
Th. K. Mavrogordatos, F. Barratt, U. Asari +3
We present evidence of metastable rare quantum-fluctuation switching for the driven dissipative Jaynes-Cummings oscillator coupled to a zero-temperature bath in the strongly disper…
Interactions in dye-microcavity photon condensates and the prospects for their observation
R. A. Nyman, M. H. Szymanska
We derive the equation of motion for a Bose-Einstein condensate of photons in a dye-microcavity system, starting from Maxwell's equations. Our theory takes into account mirror shap…
