量子随机模型中的绝热消去

Adiabatic elimination in quantum stochastic models

Luc Bouten, Andrew Silberfarb

摘要:

我们考虑一个通过量子随机微分方程耦合到玻色子储层的物理系统。当耦合强度趋于无穷大时,我们研究了该模型的极限。证明了在此极限下量子随机微分方程的解强收敛于极限量子随机微分方程的解。在极限动力学中,激发态被去除,而基态直接耦合到库。

英文摘要:

We consider a physical system with a coupling to bosonic reservoirs via a quantum stochastic differential equation. We study the limit of this model as the coupling strength tends to infinity. We show that in this limit the solution to the quantum stochastic differential equation converges strongly to the solution of a limit quantum stochastic differential equation. In the limiting dynamics the excited states are removed and the ground states couple directly to the reservoirs.
