Effective-Hamiltonian theory of open quantum systems at strong coupling

N Anto-Sztrikacs, A Nazir, D Segal - PRX Quantum, 2023 - APS
We present the reaction-coordinate polaron-transform (RCPT) framework for generating
effective-Hamiltonian models to treat nonequilibrium open quantum systems at strong …

Zero-cost corrections to influence functional coefficients from bath response functions

A Bose - The Journal of Chemical Physics, 2022 - pubs.aip.org
Recent work has shown that it is possible to circumvent the calculation of the spectral
density and directly generate the coefficients of the discretized influence functionals using …

Open Quantum System Techniques Beyond the Lindblad Equation

N Anto-Sztrikacs - 2024 - search.proquest.com
Quantum systems are inherently open to their environment and thus they evolve under the
influence of dissipation, decoherence and driving from external fields. This poses a …
