驱动耗散玻色场的变分分析

Variational analysis of driven-dissipative bosonic fields

Tim Pistorius, Hendrik Weimer

摘要:

本文提出了一种对任意大占据数的驱动耗散玻色子场的量子主方程进行变分分析的方法。我们的方法结合了密度矩阵的P表示和开放量子系统的变分原理。我们通过比较波函数蒙特卡罗模拟和Jaynes-Cummings模型的Maxwell-Bloch方程的解来基准测试该方法。此外,我们还研究了腔场中里德堡极化激元的模型,并引入了一组新的变分参数来描述不同模式之间的关联。

英文摘要:

We present a method to perform a variational analysis of the quantum master equation for driven-disspative bosonic fields with arbitrary large occupation numbers. Our approach combines the P representation of the density matrix and the variational principle for open quantum system. We benchmark the method by comparing it to wave-function Monte-Carlo simulations and the solution of the Maxwell-Bloch equation for the Jaynes-Cummings model. Furthermore, we study a model describing Rydberg polaritons in a cavity field and introduce an additional set of variational paramaters to describe correlations between different modes.
