夸克准粒子的热力学

Towards thermodynamics of the quark quasi-particles

S. V. Molodtsov, G. M. Zinovjev

摘要:

本文研究了四费米子相互作用哈密顿量模型中的准粒子--夸克热稠密气体的一些性质。适应Nambu-Jona-Lasinio模型,这种方法使我们能够容纳一个相变类似的核液-气在适当的规模,并认为存在的真空和正常重子物质的混合相的手征对称性(部分)恢复的一个合理的方案。通过分析两相之间的过渡层,估算了表面张力系数,并讨论了夸克液滴形成的可能性。

英文摘要:

Some features of hot and dense gas of quarks which are considered as the quasi-particles of the model Hamiltonian with four-fermion interaction are studied. Being adapted to the Nambu-Jona-Lasinio model this approach allows us to accommodate a phase transition similar to the nuclear liquid-gas one at the proper scale and to argue an existence of the mixed phase of vacuum and normal baryonic matter as a plausible scenario of chiral symmetry (partial) restoration. Analyzing the transition layer between two phases we estimate the surface tension coefficient and discuss the possibility of quark droplet formation.
