Thermalization of Quantum Fields from Time-Reversal Invariant Evolution Equations
J. Berges, J. Cox
We study the time evolution of correlation functions in closed quantum systems for nonequilibrium ensembles of initial conditions. For a scalar quantum field theory we show that ge…
Magnetic fields within color superconducting neutron star cores
M. Alford, J. Berges, K. Rajagopal
We discuss the Meissner effect for a color superconductor formed by cold dense quark matter. Though color and ordinary electromagnetism are broken in a color superconductor, there…
Gapless Color Superconductivity
M. Alford, J. Berges, K. Rajagopal
We present the dispersion relations for quasiparticle excitations about the color-flavor locked ground state of QCD at high baryon density. In the presence of condensates which pai…
Unlocking Color and Flavor in Superconducting Strange Quark Matter
M. Alford, J. Berges, K. Rajagopal
We explore the phase diagram of strongly interacting matter with massless u and d quarks as a function of the strange quark mass m_s and the chemical potential mu for baryon number…
The Chiral Phase Transition at High Baryon Density from Nonperturbative Flow Equations
J. Berges, D. -U. Jungnickel, C. Wetterich
We investigate the QCD chiral phase transition at high baryon number density within the linear quark meson model for two flavors. The method we employ is based on an exact renormal…
Quark and Nuclear Matter in the Linear Chiral Meson Model
J. Berges, D. -U. Jungnickel, C. Wetterich
We present an analytical description of the phase transitions from a nucleon gas to nuclear matter and from nuclear matter to quark matter within the same model. The equation of st…
