有限温度下的瞬子液体与夸克的化学势

Instanton Liquid at Finite Temperature and Chemical Potential of Quarks

S. V. Molodtsov, G. M. Zinovjev

摘要:

本文用变分原理研究了加热和强相互作用物质中的瞬子液体。瞬子液体密度(胶子凝聚)对温度和夸克化学势的依赖性是在这样的假设下确定的,即在有限的温度下,主要的贡献是由一个calorons系综。使用相应的单圈有效夸克拉格朗日量。

英文摘要:

Instanton liquid in heated and strongly interacting matter is studied using the variational principle. The dependence of the instanton liquid density (gluon condensate) on the temperature and the quark chemical potential is determined under the assumption that, at finite temperatures, the dominant contribution is given by an ensemble of calorons. The respective one-loop effective quark Lagrangian is used.
