论文摘要
我们研究了在存在均匀的外部磁场的情况下，带电粒子在谐波电位中移动的带电粒子的量子运动，并通过动量变量线性耦合与欧姆浴。我们分析了经典高温结构域和量子低温结构域中均方根位移的生长，以零点波动为主。我们还分析了位置响应函数和各种相关函数的长时间尾巴。我们注意到一些独特的特征，与磁场中带电的量子布朗粒子的通常情况不同，并通过位置变量线性耦合到欧姆浴。
We study the Quantum Brownian motion of a charged particle moving in a harmonic potential in the presence of an uniform external magnetic field and linearly coupled to an Ohmic bath through momentum variables. We analyse the growth of the mean square displacement of the particle in the classical high temperature domain and in the quantum low temperature domain dominated by zero point fluctuations. We also analyse the Position Response Function and the long time tails of various correlation functions. We notice some distinctive features, different from the usual case of a charged quantum Brownian particle in a magnetic field and linearly coupled to an Ohmic bath via position variables.
