Nonequilibrium Dynamics of High Density Matter under a Strong Magnetic Field

I present recent results on the nonequilibrium dynamics of strongly interacting matter in the presence of strong magnetic fields. First, I discuss the influence of a strong magnetic field on the time evolution of the quark condensate (scalar density) at finite temperature, studied within the linear sigma model. The dynamics of the condensate are governed by a Ginzburg–Landau–Langevin equation derived using the closed-time path (CTP) formalism of nonequilibrium quantum field theory. I then introduce a relativistic field-theoretical framework to model quark substructure effects in nucleons through deformed anticommutation relations. Preliminary results in the mean-field approximation reveal how these modifications affect the equilibrium properties of dense matter. This combined approach provides a promising framework for future investigations of magnetic field effects in both hot and cold baryonic systems.
