弯曲空间中的手征能隙效应

Chiral gap effect in curved space

Antonino Flachi, Kenji Fukushima

摘要:

本文讨论了在弯曲空间中诱导的一种新的QCD现象。在QCD真空中,狄拉克费米子的质量隙归因于手征对称性的自发破缺。当曲率为正大时,手征凝聚体熔化,但仍存在手征不变的质量隙,我们称之为弯曲空间中的手征隙效应。这导致了夸克解除禁闭的退耦,这意味着黑洞被一阶QCD相变包围的观点。

英文摘要:

We discuss a new type of QCD phenomenon induced in curved space. In the QCD vacuum, a mass-gap of Dirac fermions is attributed to the spontaneous breaking of chiral symmetry. If the curvature is positive large, the chiral condensate melts but a chiral invariant mass-gap can still remain, which we name the chiral gap effect in curved space. This leads to decoupling of quark deconfinement which implies a view of black holes surrounded by a first-order QCD phase transition.
