Onset of classical behaviour after a phase transition
R. J. Rivers, F. C. Lombardo
We analyze the onset of classical behaviour in a scalar field after a continuous phase transition, in which the system-field, the long wavelength order parameter of the model, inte…

Classical Behaviour After a Phase Transition: I. Classical Order Parameters
F. C. Lombardo, R. J. Rivers, F. D. Mazzitelli
We analyze the onset of classical field configurations after a phase transition. Firstly, we motivate the problem by means of a toy model in quantum mechanics. Subsequently, we con…

Classical Behaviour After a Phase Transition: II. The Formation of Classical Defects
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. Most likely these include transitions in the early unive…
