致密磁化物质中的手征跃迁

Chiral transition in dense, magnetized matter

Florian Preis, Anton Rebhan, Andreas Schmitt

摘要:

在化学势存在的情况下,磁场对手征对称性破缺的影响超出了众所周知的磁催化作用。由于与化学势的微妙相互作用,磁场可能不仅有利于而且不利于手性断裂相。在足够大的耦合,磁场有利于破碎的阶段,只有在磁场强度超过任何可能的值在性质上。因此,在磁星的内部,从手征破缺的强子物质到手征对称的夸克物质的可能转变可能发生在比以前认为的更小的密度。

英文摘要:

In the presence of a chemical potential, the effect of a magnetic field on chiral symmetry breaking goes beyond the well-known magnetic catalysis. Due to a subtle interplay with the chemical potential, the magnetic field may work not only in favor but also against the chirally broken phase. At sufficiently large coupling, the magnetic field favors the broken phase only for field strengths beyond any conceivable value in nature. Therefore, in the interior of magnetars, a possible transition from chirally broken hadronic matter to chirally symmetric quark matter might occur at smaller densities than previously thought.
