Quark Probability Distribution at Finite Temperature and Density
Lianyi He, Guang Bian, Jinfeng Liao, Pengfei Zhuang
Abstract
Quark deconfinement phase transition at finite temperature and density is investigated in the frame of quantum mechanics. By solving the Schrödinger equation for a heavy quark in a thermal mean field, we calculate the quark probability distribution as a function of temperature and density. The confined wave function in the vacuum expands outward rapidly when the temperature and density are high enough. The obtained phase transition line agrees qualitatively with the result of lattice QCD.
