Tomáš Brauner, Helena Kolešová

AI总结:

本文在次领头阶手征微扰理论下计算了非零重子化学势、温度和磁场下QCD手征孤子格子态的自由能,扩展了畴壁研究,验证了相图并确定了畴壁与孤子格子的磁化强度。

摘要:

我们在次领头阶手征微扰理论下计算了量子色动力学(QCD)在非零重子化学势、温度和外部磁场下的手征孤子格子态的自由能。这扩展了之前仅考虑手征孤子格子的一个特殊极限,即畴壁的研究。因此,我们的结果作为对先前确立的在中等磁场和温度以及亚核重子化学势下QCD相图的一致性检验。此外,我们利用自由能的结果确定了畴壁和手征孤子格子所携带的磁化强度,两者均在次领头阶。

英文摘要:

We compute the free energy of the chiral soliton lattice state in quantum chromodynamics (QCD) at nonzero baryon chemical potential, temperature and external magnetic field at the next-to-leading order of chiral perturbation theory. This extends previous work where only a special limit of the chiral soliton lattice, the domain wall, was considered. Our results therefore serve as a consistency check of the previously established phase diagram of QCD at moderate magnetic fields and temperature and sub-nuclear baryon chemical potentials. Moreover, we use the result for the free energy to determine the magnetization carried by the domain wall and the chiral soliton lattice, both at the next-to-leading order.
