量子布朗运动。II

Quantum Brownian motion. II

Fabian H. Gaioli, Edgardo T. Garcia Alvarez, Diego G. Arbo

摘要:

本文推广了Gaioli等的一些结果,J. Theor. Phys.36,2167(1997)。我们评估的随机加速度的自相关函数和研究的平均占有数的渐近演化的谐振子的布朗粒子的作用。我们还分析了低温下玻色布居数的一些偏差,并将其与不稳定量子系统的指数衰减律的偏差进行了比较。

英文摘要:

This paper is devoted to generalize some previous results presented in Gaioli et al., Int. J. Theor. Phys. 36, 2167 (1997). We evaluate the autocorrelation function of the stochastic acceleration and study the asymptotic evolution of the mean occupation number of a harmonic oscillator playing the role of a Brownian particle. We also analyze some deviations from the Bose population at low temperatures and compare it with the deviations from the exponential decay law of an unstable quantum system.
