手征涡旋与旋转引起的赝标凝聚
Chiral vortices and pseudoscalar condensation due to rotation
摘要：
研究了强相互作用物质中转动对动力学手征对称性破缺的影响。我们发展了一个自洽的Bogoliubov-de Gennes-like理论框架，在四费米子相互作用理论中研究旋转有限尺寸物质中的非均匀手征凝聚和可能的手征涡旋态.我们表明，足够快的旋转$2+1$维，基态可以是一个手征涡旋态，一种拓扑缺陷的超流体和超导体的类比。涡旋态表现出π凝聚，为在强相互作用物质中实现赝标凝聚提供了一种新的机制。
英文摘要：
We investigate the influence of rotation on the dynamical chiral symmetry breaking in strongly interacting matter. We develop a self-consistent Bogoliubov-de Gennes-like theoretical framework to study the inhomogeneous chiral condensate and the possible chiral vortex state in rotating finite-size matter in four-fermion interacting theories. We show that for sufficiently rapid rotation in $2+1$ dimensions, the ground state can be a chiral vortex state, a type of topological defect in analogy to superfluids and superconductors. The vortex state exhibits pion condensation, providing a new mechanism to realize pseudoscalar condensation in strongly interacting matter.
