一次元二成分量子ガスにおけるダイナミクス

由平方换向器测量的信息扰乱与谐振子中相互作用粒子的失超后功起伏成正比。对于2个粒子，这是解析的结果，直到5个粒子都得到了数值验证，解析结果表明，N个粒子也是如此。简并态的量子速度与2+2相互作用量子气体的关联性质密切相关。对于不同关联区域之间的一些猝灭，系统最初看到关联的动态重排，随后是相对恒定的关联性质，伴随着一体算符的周期振荡行为。

The information scrambling as measured by the squared commutator is shown to be directly proportional the the post-quench work fluctuations for interacting particles in a harmonic oscillator. This is analytically shown for 2 particles, numerically confirmed for up til 5 particles and analytic arguments imply that it must be true for N particles as well.Quantum speeds of reduced states are shown to be closely related to the correlation properties for 2+2 interacting quantum gases. For some quenches between different correlation regimes the system initially sees a dynamical rearrangement of the correlations, followed by relatively constant correlation properties accompanied by periodic oscillating behavior of one-body operators.
