Non-equilibrium quantum thermometry with bosonic samples
Marek Winczewski, Michał Horodecki, Ricard Ravell Rodríguez
We study low-temperature non-equilibrium quantum thermometry with a bosonic probe: a quantum harmonic oscillator strongly coupled to a bosonic bath at temperature through a Dru…
Equivalence of Discrete and Continuous Otto-Like Engines assisted by Catalysts: Mapping Catalytic Advantages from the Discrete to the Continuous Framework
Marcin Łobejko, Tanmoy Biswas, Michał Horodecki
The catalytic extension of a discrete two-stroke engine employs a cyclic auxiliary system - the catalyst - that remains decoupled from the baths and performs no work, yet enhances…
Open quantum dynamics of Josephson charge pumps
Ankit Kumar, Luis Cort, Marcin Łobejko +2
We investigate the macroscopic dynamics of Josephson charge pumps in the light of Alicki et al.'s theoretical description of the Josephson junction as an open quantum system descri…
Dynamics of the Non-equilibrium spin Boson Model: A Benchmark of master equations and their validity
Gerardo Suárez, Marcin Łobejko, Michał Horodecki
In recent years, there has been tremendous focus on identifying whether effective descriptions of open quantum systems such as master equations, can accurately describe the dynamic…
Catalytic enhancement in the performance of the microscopic two-stroke heat engine
Tanmoy Biswas, Marcin Łobejko, Paweł Mazurek +1
We consider a model of heat engine operating in the microscopic regime: the two-stroke engine. It produces work and exchanges heat in two discrete strokes that are separated in tim…
Catalytic advantage in Otto-like two-stroke quantum engines
Marcin Łobejko, Tanmoy Biswas, Paweł Mazurek +1
We demonstrate how to incorporate a catalyst to enhance the performance of a heat engine. Specifically, we analyze efficiency in one of the simplest engines models, which operates…
