全计数统计的运动方程方法:稳态超辐射

Equation of motion method for Full Counting Statistics: Steady state superradiance

Malte Vogl, Gernot Schaller, Eckehard Schöll, Tobias Brandes

摘要:

对于具有集体玻色子传输的多模Dicke模型,我们构造了累积量母函数的运动方程。近似的确切系统的方程的累积量生成函数和系统运营商在最低阶的水平,使我们能够恢复主方程的结果的全计数统计的某些参数制度在非常低的计算成本。热力学极限,这是无法访问的主方程的方法,可以推导出不同的近似解析。

英文摘要:

For the multi-mode Dicke model in a transport setting that exhibits collective boson transmissions, we construct the equation of motion for the cumulant generating function. Approximating the exact system of equations at the level of cumulant generating function and system operators at lowest order, allows us to recover master equation results of the Full Counting Statistics for certain parameter regimes at very low cost of computation. The thermodynamic limit, that is not accessible with the master equation approach, can be derived analytically for different approximations.
