Equivalence of Discrete and Continuous Otto-Like Engines assisted by Catalysts: Mapping Catalytic Advantages from the Discrete to the Continuous Framework
Marcin Åobejko, Tanmoy Biswas, MichaÅ 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 Åobejko +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…
Corrections to the Hamiltonian induced by finite-strength coupling to the environment
Marcin Åobejko, Marek Winczewski, Gerardo Suárez +2
If a quantum system interacts with the environment, then the Hamiltonian acquires a correction known as the Lamb-shift term. There are two other corrections to the Hamiltonian, rel…
Dynamics of the Non-equilibrium spin Boson Model: A Benchmark of master equations and their validity
Gerardo Suárez, Marcin Åobejko, MichaÅ 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…
