论文:开放系统模拟复杂度和张量网络

Luchnikov, I. A., Vintskevich, S. V., Ouerdane, H., & Filippov, S. N. (2019). Simulation Complexity of Open Quantum Dynamics: Connection with Tensor Networks. Physical Review Letters, 122(16), 160401. https://doi.org/10.1103/PhysRevLett.122.160401

TRN, Timeline reservoir network

Semi group

Poincare recurrence time: the time it takes for the system to go back to the current state.
For thermalized system it is infinity.

Non-Markovian open system dynamics: system and environment time scales not separable

??Correlation Function

Time scales: reservoir correlation timescale and dynamic timescale

Lamb shift?? splits the and states which are otherwise degenerate.

Why Renyi entropy??
