变形耗散阻尼谐振子的Lindblad主方程

Lindblad master equation for the damped harmonic oscillator with deformed dissipation

A. Isar, A. Sandulescu, W. Scheid

摘要:

在开放量子系统的Lindblad理论框架下,导出了基于变形代数的量子谐振子与耗散环境,特别是与热浴相互作用的主方程.观测量的运动方程强烈依赖于形变函数。在热浴温度为零的情况下,在小变形参数的极限下,计算了数算符和平方数算符的期望值。得到了密度矩阵方程的稳态解,并证明了其与变形无关。

英文摘要:

In the framework of the Lindblad theory for open quantum systems, a master equation for the quantum harmonic oscillator interacting with a dissipative environment, in particular with a thermal bath, is derived for the case when the interaction is based on deformed algebra. The equations of motion for observables strongly depend on the deformation function. The expectation values of the number operator and squared number operator are calculated in the limit of a small deformation parameter for the case of zero temperature of the thermal bath. The steady state solution of the equation for the density matrix in the number representation is obtained and its independence of the deformation is shown.
