弯曲空间中的手征调制II:锥状几何

Chiral Modulations in Curved Space II: Conifold Geometries

Antonino Flachi

摘要:

在本文中,我们扩展了我们以前的分析有关形成的非均匀凝聚体的强耦合费米子有效场论弯曲空间,并包括锥几何的情况下,代表最简单的听话的情况下,流形曲率奇点。在这里考虑的设置中,通过保持真正的结晶温度恒定,我们可以挑出曲率效应对手征对称性的破坏/恢复和对非均匀相的出现所起的作用。本文的第一个目标是在一般黎曼光滑基底(广义锥)的锥几何上构造四费米子有效场论情形下非均匀凝聚有限温度有效作用量的一般表达式。另一个目标是数值实现上述形式的结果,并构造自洽的解决方案的凝聚。我们明确地表明,冷凝物假设一个扭结状的配置文件,消失在奇异的是由恢复手征对称性相的气泡包围。

英文摘要:

In this paper, we extend our previous analysis concerning the formation of inhomogeneous condensates in strongly-coupled fermion effective field theories on curved spaces and include the case of conifold geometries that represent the simplest tractable case of manifolds with curvature singularities. In the set-up considered here, by keeping the genuine thermodynamical temperature constant, we may single out the role that curvature effects play on the breaking/restoration of chiral symmetry and on the appearance of inhomogeneous phases. The first goal of this paper is to construct a general expression of the finite temperature effective action for inhomogeneous condensates in the case of four-fermion effective field theories on conifold geometries with generic Riemannian smooth base (generalised cones). The other goal is to implement numerically the above formal results and construct self-consistent solutions for the condensate. We explicitly show that the condensate assumes a kink-like profile, vanishing at the singularity that is surrounded by a bubble of restored chiral symmetry phase.
