Chiral Mesons in Hot Matter
A. Gomez Nicola, F. J. LLanes-Estrada, J. R. Pelaez
We review our recent work on thermal meson properties within the Chiral Perturbation Theory framework. We will focus on the pion electromagnetic form factor, stressing its importan…
Nonequilibrium Chiral Dynamics and Effective Lagrangians
A. Gomez Nicola
We review our recent work on Chiral Lagrangians out of thermal equilibrium, which are introduced to analyse the pion gas formed after a Relativistic Heavy Ion Collision. Chiral Per…
Exploiting duality in a toy model of QCD at non-zero temperature and chemical potential: the massive Thirring model, sine-Gordon model and Coulomb gases
D. A. Steer, A. Gomez Nicola, R. J. Rivers +1
We focus on the massive Thirring model in 1+1 dimensions at finite temperature and non-zero chemical potential, and comment on some parallels between this model and QCD. In QCD, ca…
Nonequilibrium chiral perturbation theory
A. Gomez Nicola
We explore the extension of chiral perturbation theory out of thermal equilibrium. The pion decay constant becomes then a time-dependent function and we work within the Schwinger-K…
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…
