Bohmian动力学中|Psi| ^2的稳定性
Stability properties of |Psi|^2 in Bohmian dynamics
摘要:
根据玻姆动力学,量子系统的粒子沿着轨道移动,遵循由波函数Psi(x,t)确定的速度场。我们证明了对于简单的一维系统,统计系综的任何初始概率分布都渐近地逼近|Psi(x,t)|如果系统受到任意小强度的随机噪声的影响,则为^2。
英文摘要:
According to Bohmian dynamics, the particles of a quantum system move along trajectories, following a velocity field determined by the wave-function Psi(x,t). We show that for simple one-dimensional systems any initial probability distribution of a statistical ensemble approaches asymptotically |Psi(x,t)}|^2 if the system is subject to a random noise of arbitrarily small intensity.
