- Abstract: We experimentally study the infinite-size limit of the Dicke model of quantum
optics with a parity-breaking deformation strength that couples the system to
an external bosonic reservoir. We focus on the dynamical consequences of such
symmetry-breaking, which makes the classical phase space asymmetric with
non-equivalent energy wells. We present an experimental implementation of the
classical version of the deformed Dicke model using a state-of-the-art
bi-parametric electronic platform. Our platform constitutes a playground for
studying representative phenomena of the deformed Dicke model in electrical
circuits with the possibility of externally controlling parameters and initial
conditions. In particular, we investigate the dynamics of the ground state,
various phase transitions, and the asymmetry of the energy wells as a function
of the coupling strength $\gamma$ and the deformation strength $\alpha$ in the
resonant case. Additionally, to characterize the various behavior regimes, we
present a two-dimensional phase diagram as a function of the two intrinsic
system parameters. The onset of chaos is also analyzed experimentally. Our
findings provide a clear connection between theoretical predictions and
experimental observations, demonstrating the usefulness of our bi-parametric
electronic setup.

We compute the geometric phases acquired in both unitary and dissipative Jaynes-Cummings models.
