Bath-induced interactions and transient dynamics in open quantum systems at strong coupling: Effective Hamiltonian approach
Marlon Brenes, Brett Min, Nicholas Anto-Sztrikacs +2
Understanding the dynamics of dissipative quantum systems, particularly beyond the weak coupling approximation, is central to various quantum applications. While numerically exact…
Bath-engineering magnetic order in quantum spin chains: An analytic mapping approach
Brett Min, Nicholas Anto-Sztrikacs, Marlon Brenes +1
Dissipative processes can drive different magnetic orders in quantum spin chains. Using a non-perturbative analytic mapping framework, we systematically show how to structure diffe…
Bypassing thermalization timescales in temperature estimation using prethermal probes
Nicholas Anto-Sztrikacs, Harry J. D. Miller, Ahsan Nazir +1
We introduce prethermal temperature probes for sensitive, fast and robust temperature estimation. While equilibrium thermal probes with a manifold of quasidegenerate excited states…
Effective-Hamiltonian theory: An approximation to the equilibrium state of open quantum systems
Nicholas Anto-Sztrikacs, Brett Min, Marlon Brenes +1
We extend and benchmark the recently-developed Effective-Hamiltonian (EFFH) method [PRX Quantum , 020307 (2023)] as an approximation to the equilibrium state ("mean-force G…
Hyper-acceleration of quantum thermalization dynamics by bypassing long-lived coherences: An analytical treatment
Felix Ivander, Nicholas Anto-Sztrikacs, Dvira Segal
We develop a perturbative technique for solving Markovian quantum dissipative dynamics, with the perturbation parameter being a small gap in the eigenspectrum. As an example, we ap…
Effective Hamiltonian theory of open quantum systems at strong coupling
Nicholas Anto-Sztrikacs, Ahsan Nazir, Dvira Segal
We present the reaction-coordinate polaron-transform (RCPT) framework for generating effective Hamiltonian models to treat nonequilibrium open quantum systems at strong coupling wi…
