Spectral functions in the sigma-channel near the critical end point
Kenji Fukushima
Spectral functions in the -channel are investigated near the chiral critical end point (CEP), that is, the point where the chiral phase transition ceases to be first-ordered in…

Effects of chiral restoration on the behaviour of the Polyakov loop at strong coupling
Kenji Fukushima
We discuss the relation between the Polyakov loop and the chiral order parameter at finite temperature. For that purpose we analyse an effective model proposed by Gocksch and Ogilv…

Thermodynamic limit of the canonical partition function with respect to the quark number in QCD
Kenji Fukushima
We investigate QCD in the canonical ensemble with respect to the quark number. We reveal that the canonical description in which the quark number is fixed would be reduced to the g…
