Description
The canonical partition function is related to the grand canonical one
through the fugacity expansion.
In this talk we perform the fugacity expansion by a method of the
hopping parameter expansion in temporal direction.
The canonical partition function is evaluated for Nf=2 QCD upto
baryon numbers of nB=30 in a wide range of temperature.
After derivation of the canonical partition function we study the
chemical potential dependences of hadronic observables like chiral
condensate, quark number density and its susceptibility.
In this talk we report a phase transition found at real chemical potential
and its dependence on the quark mass and the volume.
