Competing Holographic Orders

Pallab Basu, Jianyang He, Anindya Mukherjee, Moshe Rozali, Hsien-Hang Shieh

摘要:

我们在全息背景下模拟不同宏观秩序之间的竞争。我们考虑的序是超导序,由带电标量场,和中性标量场模型化的磁序。我们还讨论了两个竞争标量耦合到一个单一的规范场的情况。在这里讨论的所有情况下,阶段往往是竞争的,而不是相互增强。一个标量的凝聚阻碍了任何进一步的不稳定性,除非我们有一个足够强的排斥相互作用之间的大量标量。我们提供了这一事实的分析参数和数值演示。基于这里讨论的情况下,我们推测,全息订单往往竞争有吸引力的散装相互作用,包括重力,并合作,或相互增强,为相应的序参量之间的排斥散装相互作用。

英文摘要:

We model competition between different macroscopic orders in an holographic context. The orders we considered are a superconducting order, modeled by a charged scalar field, and a magnetic order modeled by a neutral scalar field. We also discuss the case of two competing scalars coupled to a single gauge field. In all cases discussed here the phases tend to compete, rather than enhance each other. The condensation of one scalar hinders any further instabilities, unless we have a sufficiently strong repulsive interactions between the bulk scalars. We provide both analytic arguments and numerical demonstration of this fact. Based on the cases discussed here, we conjecture that holographic orders tend to compete for attractive bulk interactions, including gravity, and to cooperate, or be mutually enhancing, for repulsive bulk interactions between the corresponding order parameters.
