Kinks versus fermions or the 2D sine-Gordon versus massive Thirring models, at nonzero temperature and chemical potential
A. Gomez Nicola, R. J. Rivers, D. A. Steer
We study bosonisation in the massive Thirring and sine-Gordon models at finite temperature and nonzero fermion chemical potential. Both canonical operator and path integral approac…

Chiral Lagrangians out of thermal equilibrium
Angel Gomez Nicola
We extend Chiral Perturbation Theory to study a meson gas out of thermal equilibrium. We assume that the system is initially in equilibrium at a temperature below the phase transit…
