The Creation of Defects with Core Condensation
Nuno D. Antunes, Pedro Gandra, Ray J. Rivers +1
Defects in superfluid 3He, high-Tc superconductors, QCD colour superfluids and cosmic vortons can possess (anti)ferromagnetic cores, and their generalisations. In each case there i…

Domain Formation: Decided Before, or After the Transition?
Nuno D. Antunes, Pedro Gandra, Ray J. Rivers
There is increasing evidence that causality provides useful bounds in determining the domain structure after a continuous transition. In devising their scaling laws for domain size…

The Effects of Multiplicative Noise in Relativistic Phase Transitions
Nuno D. Antunes, Pedro Gandra, Ray J. Rivers
Effective stochastic equations for the continuous transitions of relativistic quantum fields inevitably contain multiplicative noise. We examine the effect of such noise in a numer…
