Abstract
A real-time formalism is proposed to incorporate finite
temperatures into confined quark systems at the example of the Generalised
Nambu-Jona-Lasinio model for QCD. This approach
allows one to study various properties of the system at T>0, such as
chiral symmetry breaking and restoration, properties of the bound-state
spectrum, and so on.
