宇称破缺导致自旋为1的超导体的基态螺旋有序
Helical ordering in the ground state of spin-one color superconductors as a consequence of parity violation
摘要：
我们用Ginzburg-Landau理论研究了单夸克味的自旋一色超导。首先，我们检查了经典的分析柏林和爱，并表明，通过限制到所谓的惰性状态，它错过了真正的基态的相图的一部分。这表明使用更一般的非惰性态，特别是在三味夸克物质中，色中性约束对自旋1配对施加压力，可能不利于对称的色自旋锁定态。在本文的第二部分中，我们表明，在类比一些铁磁材料，缺乏空间反演对称性导致一个新的长期的金斯堡-朗道功能，这有利于空间不均匀的长程有序的螺旋结构。在色超导体中，这个新的宇称违反项是弱相互作用物理的一个微小效应。确定了修正的相图，并构造了所有相对应的基态。最后，我们估计了自由能泛函中新项的系数，并讨论了它与稠密夸克物质唯象学的关系。
英文摘要：
We investigate spin-one color superconductivity of a single quark flavor using the Ginzburg-Landau theory. First we examine the classic analysis of Bailin and Love and show that by restricting to the so-called inert states, it misses the true ground state in a part of the phase diagram. This suggests the use of the more general, noninert states in particular within three-flavor quark matter where the color neutrality constraint imposes stress on the spin-one pairing and may disfavor the symmetric color-spin-locked state. In the second part of the paper we show that, in analogy to some ferromagnetic materials, lack of space-inversion symmetry leads to a new term in the Ginzburg-Landau functional, which favors a spatially nonuniform long-range ordering with a spiral structure. In color superconductors, this new parity-violating term is a tiny effect of weak-interaction physics. The modified phase diagram is determined and the corresponding ground states for all the phases constructed. At the end, we estimate the coefficient of the new term in the free energy functional, and discuss its relevance for the phenomenology of dense quark matter.
