耗散驱动量子系统的实时模拟

Real-time simulation of dissipation-driven quantum systems

Debasish Banerjee, Florian Hebenstreit, Fu-Jiun Jiang, Mark Kon, Uwe-Jens Wiese

摘要:

我们建立了一个实时的路径积分来研究完全由系统与环境的耦合实时驱动的量子系统的演化。对于特定选择的交互,这可以被解释为在系统上执行的测量。对于自旋为1/2的系统,特别是当测量结果被平均时,所产生的符号问题完全消失,并且可以用有效的聚类算法来模拟该系统。

英文摘要:

We set up a real-time path integral to study the evolution of quantum systems driven in real-time completely by the coupling of the system to the environment. For specifically chosen interactions, this can be interpreted as measurements being performed on the system. For a spin-1/2 system, in particular, when the measurement results are averaged over, the resulting sign problem completely disappears, and the system can be simulated with an efficient cluster algorithm.
