Coherent and squeezed condensates in massless theory
H. -P. Pavel, D. Blaschke, G. Roepke +1
Generalizing the Bogoliubov model of a weakly non-ideal Bose gas to massless theory we show that spontaneous breaking of symmetry occurs due to condensation in a coherent va…
1/N_c- expansion of the quark condensate at finite temperature
D. Blaschke, Yu. L. Kalinovsky, G. Roepke +2
Previously the quark and meson properties in a many quark system at finite temperature have been studied within effective QCD approaches in the Hartree approximation. In the presen…
Bogoliubov condensation of gluons and spontaneous gauge symmetry breaking in QCD
V. N. Pervushin, G. Roepke, M. K. Volkov +3
The problem of the gluonic quasiparticle excitations in QCD is considered under the aspect of the condensation of gluon pairs in the ''squeezed'' vacuum. The present approach is a…
