Defect formation in superconducting rings: external fields and finite-size effects
D. J. Weir, R. Monaco, R. J. Rivers
Consistent with the predictions of Kibble and Zurek, scaling behaviour has been seen in the production of fluxoids during temperature quenches of superconducting rings. However, de…
Which Green Functions Does the Path Integral for Quasi-Hermitian Hamiltonians Represent?
H. F. Jones, R. J. Rivers
In the context of quasi-Hermitian theories, which are non-Hermitian in the conventional sense, but can be made Hermitian by the introduction of a dynamically-determined metric ,…
Decoherence of domains and defects at phase transitions
F. C. Lombardo, R. J. Rivers, P. I. Villar
In this further letter on the onset of classical behaviour in field theory due to a phase transition, we show that it can be phrased easily in terms of the decoherence functional,…
How Phase Transitions induce classical behaviour
R. J. Rivers, F. C. Lombardo
We continue the analysis of the onset of classical behaviour in a scalar field after a continuous phase transition, in which the system-field, the long wavelength order parameter o…
The Formation of Classical Defects After a Slow Quantum Phase Transition
R. J. Rivers, F. C. Lombardo, F. D. Mazzitelli
Classical defects (monopoles, vortices, etc.) are a characteristic consequence of many phase transitions of quantum fields. We show a model in which the onset of classical probabil…
Transport Coefficients and Analytic Continuation in Dual 1+1 Dimensional Models at Finite Temperature
T. S. Evans, A. Gomez Nicola, R. J. Rivers +1
The conductivity of a finite temperature 1+1 dimensional fermion gas described by the massive Thirring model is shown to be related to the retarded propagator of the dual boson sin…
