Nonadiabatic landau–zener–stückelberg–majorana transitions, dynamics, and interference
Since the pioneering works by Landau, Zener, Stückelberg, and Majorana (LZSM), it has
been known that driving a quantum two-level system results in tunneling between its states …

Ergotropy from coherences in an open quantum system
B Çakmak - Physical Review E, 2020 - APS
We show that it is possible to have nonzero ergotropy in the steady states of an open
quantum system consisting of qubits that are collectively coupled to a thermal bath at a finite …

Collective effects and quantum coherence in dissipative charging of quantum batteries
F Mayo, AJ Roncaglia - Physical Review A, 2022 - APS
We consider the dissipative charging process of quantum batteries in terms of a collisional
model, where the batteries are coupled to a heat bath using nonenergy preserving …

Degenerated Liouvillians and steady-state reduced density matrices
Symmetries in an open quantum system lead to degenerated Liouvillians that physically
imply the existence of multiple steady states. In such cases, obtaining the initial condition …

Two-stroke quantum measurement heat engine
MS Alam, BP Venkatesh - arXiv preprint arXiv:2201.06303, 2022 - arxiv.org
We propose and analyze the theoretical model for a two-stroke quantum heat engine with
one of the heat baths replaced by a non-selective quantum measurement. We show that the …
