Kibble-Zurek机制描述在有限速率连续相变过程中系统的非平衡动力学和拓扑缺陷的形成。 Tom Kibble等人指出,如果在极早期宇宙的冷却和膨胀过程中,双分量标量场(例如希格斯场,伴生于基本粒子希格斯玻色子)从各向同性和均匀的高温阶段切换到对称破缺阶段,在宇宙中距离足够远的区域没有相互连接,没有因果关系(not connected by...

trapped ionsuniversal scaling lawThe Kibble-Zurek(KZ)mechanism has played a fundamental role in defect formation with universal scaling laws in nonequilibrium phase transitions.However,this theory may not accurately predict the scaling laws in inhomogeneous systems and slow quenching processes.Here,w...
Exceptional points (EPs) are ubiquitous in non-Hermitian systems, and represent the complex counterpart of critical points. By driving a system through a critical point at finite rate induces defects, described by the Kibble-Zurek mechanism, which finds

We show that the Kibble-Zurek mechanism applies to nonequilibrium phase transitions found in driven assemblies of superconducting vortices and colloids moving over quenched disorder where a transition occurs from a plastic disordered flowing state to a m
The Kibble-Zurek mechanism (KZM) predicts the density of topological defects produced in the dynamical processes of phase transitions in systems ranging from cosmology to condensed matter and quantum materials. The similarity between KZM and the Landau-Zener transition (LZT), which is a standard tool...
