论文摘要
我们研究了一个由自propell的活性粒子组成的相互多体系统的稳态和动力学特性，这些粒子具有局部比对相互作用，这些相互作用存在于每个粒子的扇形邻域内。我们发现，一旦存在自发对称性破裂，就可以在此倒数系统中出现非股骨，并且对系统的有效描述假定直接源自新出现的非肾脏性的非热结构。这种新出现的非进取心可以对系统的性质产生强大的影响。特别是，它甚至可以驱动活性颗粒的真实空间冷凝。我们的发现铺平了道路，为识别由紧急非企业驱动的互惠系统中的一类新的物理学铺平了道路。
We investigate the steady-state and dynamical properties of a reciprocal many-body system consisting of self-propelled active particles with local alignment interactions that exists within a fan-shaped neighborhood of each particle. We find that the nonreciprocity can emerge in this reciprocal system once the spontaneous symmetry breaking is present, and the effective description of the system assumes a non-Hermitian structure that directly originates from the emergent nonreciprocity. This emergent nonreciprocity can impose strong influences on the properties the system. In particular, it can even drive a real-space condensation of active particles. Our findings pave the way for identifying a new class of physics in reciprocal systems that is driven by the emergent nonreciprocity.
