Liouville-von Neumann方程波传播子的可积性
On the integrability of the wave propagator arising from the Liouville-von Neumann equation
摘要:
Liouville-von Neumann方程描述了密度矩阵随时间的变化。有趣的是,这个方程最近被认为是波函数的波动方程,而不是密度函数的方程。这种设置导致了薛定谔波动方程的扩展形式,它控制着量子粒子的运动。在本文中,我们得到的可积性的波传播所产生的Liouville-vonNeumann方程在此设置。
英文摘要:
The Liouville-von Neumann equation describes the change in the density matrix with time. Interestingly, this equation was recently regarded as a wave equation for wave functions but not a equation for density functions. This setting leads to an extended form of the Schrödinger wave equation governing the motion of a quantum particle. In this paper we obtain the integrability of the wave propagator arising from the Liouville-von Neumann equation in this setting.
