Which Otto Engine Is the Fastest?
Idriss Hank Nkouatchoua Ngueya, Marcin Łobejko
A general thermal machine is characterized by distinct time or energy scales: temperature, coupling to the heat baths, internal free dynamics and interactions, and external driving…
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…
