QCD thermodynamics at 0
· Interesting properties of QCD
Measurable in heavy-ion collisions
Critical point at finite density
· Methods for the high density region: required
· Most difficult problem: "sign problem"
In this talk
· Propose a method to avoid the sign problem.
· Discuss an effective potential as a function of the total quark number
and the nature of phase transitions at finite density.
