Unified Framework for Open Quantum Dynamics with Memory
Felix Ivander, Lachlan P. Lindoy, Joonho Lee
Studies of the dynamics of a quantum system coupled to baths are typically performed by utilizing the Nakajima-Zwanzig memory kernel () or the influence functions ($…
Quantum coherence-control of thermal energy transport: The V model as a case study
Felix Ivander, Nicholas Anto-Sztrikacs, Dvira Segal
Here, we study a minimal model, the three-level V system coupled to two heat baths, and investigate the role of quantum coherences in heat transport in both the transient regime an…
Quantum Thermal Transport Beyond Second Order with the Reaction Coordinate Mapping
Nicholas Anto-Sztrikacs, Felix Ivander, Dvira Segal
Standard quantum master equation techniques such as the Redfield or Lindblad equations are perturbative to second order in the microscopic system-reservoir coupling parameter .…
Strong system-bath coupling reshapes characteristics of quantum thermal machines
Felix Ivander, Nicholas Anto-Sztrikacs, Dvira Segal
We study the performance of quantum absorption refrigerators, paradigmatic autonomous quantum thermal machines, and reveal central impacts of strong couplings between the working s…
Reply to "Comment on "Unified Framework for Open Quantum Dynamics with Memory""
Felix Ivander, Lachlan P. Lindoy, Joonho Lee
We present our response to the commentary piece by Makri {\it et al.} [arXiv:2410.08239], which raises critiques of our work [Nat. Commun. 15, 8087 (2024)]. In our paper, we consid…
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…
