Sixth-order time-convolutionless master equation and beyond: Late-time resummations, two types of divergences, and the limits of validity
Lance Lampert, Srikar Gadamsetty, Shantanu Chaudhary +4
Perturbative master equations are essential for modeling open quantum systems but often exhibit late-time divergences when environmental correlations decay algebraically. In this w…

Benchmarking TCL4: Assessing the Usability and Reliability of Fourth-Order Approximations
Jiahao Chen, Elyana Crowder, Lian Xiang +1
The non-Markovian dynamics of an open quantum system can be rigorously derived using the Feynman-Vernon influence functional approach. Although this formalism is exact, practical n…
