Abstract

The nonperturbative QCD vacuum at finite temperature and a finite baryon density in an external magnetic field is studied. Equations relating nonperturbative condensates to the thermodynamic pressure for , and are obtained, and low-energy theorems are derived. A bulk viscosity is expressed in terms of basic thermodynamical quantities describing the quark-gluon matter at , , and . Various limiting cases are also considered.
