具有扩散和耗散的变形量子谐振子

Deformed quantum harmonic oscillator with diffusion and dissipation

A. Isar, W. Scheid

摘要:

在微观模型中,利用微扰理论导出了变形量子谐振子与耗散环境,特别是与热浴相互作用的主方程。主方程和观测量运动方程的系数取决于变形函数。在小变形近似下,求出了密度矩阵方程在数表象下的稳态解,并计算了变形谐振子的平衡能。

英文摘要:

A master equation for the deformed quantum harmonic oscillator interacting with a dissipative environment, in particular with a thermal bath, is derived in the microscopic model by using perturbation theory. The coefficients of the master equation and of equations of motion for observables depend on the deformation function. The steady state solution of the equation for the density matrix in the number representation is obtained and the equilibrium energy of the deformed harmonic oscillator is calculated in the approximation of small deformation.
