热态QCD中的手征孤子晶格相

Chiral soliton lattice phase in warm QCD

Tomáš Brauner, Helena Kolešová, Naoki Yamamoto

摘要:

在次导阶导数展开的手征微扰理论下,分析了中低温、重子化学势和外加磁场条件下的量子色动力学相图。我们的主要结果是,反常诱导的手征孤子晶格(CSL)的相位是稳定的热涨落。因此,CSL状态可以存活到手征对称性恢复的温度。

英文摘要:

We analyze the phase diagram of quantum chromodynamics at low-to-moderate temperature, baryon chemical potential and external magnetic field within chiral perturbation theory at next-to-leading order of the derivative expansion. Our main result is that the anomaly-induced chiral soliton lattice (CSL) phase is stabilized by thermal fluctuations. As a consequence, the CSL state may survive up to temperatures at which chiral symmetry is restored.
