Ferromagnetism of two-flavor quark matter in chiral and/or color-superconducting phases at zero and finite temperatures
M. Inui, H. Kohyama, A. Niégawa
We study the phase structure of the unpolarized and polarized two-flavor quark matters at zero and finite temperatures within the Nambu--Jona-Lasinio (NJL) model. We focus on the r…
Out of equilibrium O (N) linear-sigma system - Construction of perturbation theory with gap- and Boltzmann-equations
A. Niégawa
We establish from first principles a perturbative framework that allows us to compute reaction rates for processes taking place in nonequilibrium linear-sigma systems in br…
Out of Equilibrium Relativistic Quantum Field Theory --- Perturbation Theory and Progress of Phase Transition
A. Niégawa
This paper describes perturbative framework, on the basis of closed-time-path formalism, for studying quasiuniform relativistic quantum field systems near equilibrium and nonequili…
Self-consistent determination of hard modes in hot QCD
A. Niégawa
We determine self-consistently the hard-quark and hard-gluon modes in hot QCD. The damping-rate part in resummed hard-quark or hard-gluon propagators, rather than the thermal-mass…
