Real-time simulation of dissipation-driven quantum systems

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

Abstract

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\ud disappears, and the system can be simulated with an efficient cluster algorithm
