An Exact Operator Formulation of Statistical Quasiparticle Theory for Nonlinear System-Bath Coupling
Yu Su, Yao Wang
We develop an operator formulation of statistical quasiparticle theory for open quantum systems with nonlinear system-bath coupling, extending beyond the linear coupling setting of…

Unit-Circle Moment Closure
Yu Su, Yao Wang
Moment closure is a central problem in reduced descriptions of stochastic, kinetic, and quantum dynamics, where equations for low-order observables are coupled to an unresolved hie…

Projection-Based Memory Kernel Coupling Theory for Quantum Dynamics: A Stable Framework for Non-Markovian Simulations
Wei Liu, Rui-Hao Bi, Yu Su +4
We present a projection-based, stability-preserving methodology for computing time correlation functions in open quantum systems governed by generalized quantum master equations wi…
