Collective spin systems in dispersive optical cavity QED: Quantum phase transitions and entanglement
S. Morrison, A. S. Parkins
We propose a cavity QED setup which implements a dissipative Lipkin-Meshkov-Glick model -- an interacting collective spin system. By varying the external model parameters the syste…
Dynamical quantum phase transitions in the dissipative Lipkin-Meshkov-Glick model and proposed realization in optical cavity QED
S. Morrison, A. S. Parkins
We present an optical cavity QED configuration that is described by a dissipative version of the Lipkin-Meshkov-Glick model of an infinitely coordinated spin system. This open quan…
An Application of Feynman-Kleinert Approximants to the Massive Schwinger Model on a Lattice
T. M. R. Byrnes, C. J. Hamer, Zheng Weihong +1
A trial application of the method of Feynman-Kleinert approximants is made to perturbation series arising in connection with the lattice Schwinger model. In extrapolating the latti…
Numerical Portrait of a Relativistic Thin Film BCS Superfluid
Simon Hands, Biagio Lucini, Susan Morrison
We present results of numerical simulations of the 2+1d Nambu - Jona-Lasinio model with a non-zero baryon chemical potential mu including the effects of a diquark source term. Diqu…
Two-colour QCD at non-zero quark-number density
J. B. Kogut, D. K. Sinclair, S. J. Hands +1
We have simulated two-colour four-flavour QCD at non-zero chemical potential for quark number. Simulations were performed on and lattices. Clear evidence…
QED with Dynamical Fermions in an External Magnetic Field
J. Alexandre, K. Farakos, S. J. Hands +2
In this paper, we present results of numerical lattice simulations of two-flavor QED in three space-time dimensions. First, we provide evidence that chiral symmetry is spontaneousl…
