有限温度下QCD的Hamilton近似

Hamiltonian approach to QCD at finite temperature

Hugo Reinhardt, Davide Campagnari, Markus Quandt

摘要:

本文提出了一种新的有限温度下量子场论的哈密顿公式。温度是通过空间维度的紧化引入的。整个有限温度理论被编码在空间流形$S^1 (L) \times \mathbb{R}^2$上的基态中,其中$L$是定义逆温度的紧致维数的长度。然后将此方法应用于库仑规范中QCD的哈密顿表述,研究了有限温度下的手征相变。

英文摘要:

A novel approach to the Hamiltonian formulation of quantum field theory at finite temperature is presented. The temperature is introduced by compactification of a spatial dimension. The whole finite-temperature theory is encoded in the ground state on the spatial manifold $S^1 (L) \times \mathbb{R}^2$ where $L$ is the length of the compactified dimension which defines the inverse temperature. The approach which is then applied to the Hamiltonian formulation of QCD in Coulomb gauge to study the chiral phase transition at finite temperatures.
