报告摘要: We study the real-time simulation of open quantum systems, where the system is modeled by a diagram that represents the connection between spins, with each spin associated with its own harmonic bath. Our method first decoupled the system to be a single spin problem and the inchworm method is applied for the single spin problem. By designing proper data structure, the quantities on single spin can be formally considered as a tensor. Connecting single spins to the full diagram therefore becomes tensor operators. Numerical test will be carried out in some simple examples to validate our method.
