Thermoelectric information engine driven by an autonomous Maxwell demon across quantum-to-classical transitions
Maximiliano Bernal Santibañez, Felipe Barra, Jose Mondaca
We study a three-terminal thermoelectric engine, focusing on the role of quantum coherence and information flow. A double-dot connects two reservoirs at different chemical potentia…
Thermalization in Spatially Extended Open Quantum Systems: Local versus Global Markovian Evolution
Jorge Tabanera-Bravo, Massimiliano Esposito, Felipe Barra +1
We investigate the dynamics of a qubit chain locally coupled to a thermal reservoir, modeled through repeated collisions with particles drawn from a heat bath. Under suitable condi…
Bosonic Working Media in a Frustrated Rhombi Chain: Otto and Stirling Cycles from Flat Bands, Caging, and Flux Control
Francisco J. Peña, Rafael García-Zamora, Gabriele De Chiara +5
We demonstrate that flat-band engineering provides a direct route to control and optimize the thermodynamic performance of quantum heat engines. We consider noninteracting bosons o…
Caloric Phenomena and Stirling-Cycle Performance in Heisenberg- Kitaev Magnon Systems
Bastian Castorene, Martin HvE Groves, Francisco J. Peña +5
We investigate the Stirling-cycle performance of a Heisenberg--Kitaev magnonic medium with Dzyaloshinskii--Moriya (DM) interactions. Using linear spin-wave theory, we show the DM i…
Daemonic quantum battery charged by thermalization
Matias Araya Satriani, Felipe Barra
The reduced state of a small system strongly coupled to a charger in thermal equilibrium may be athermal and used as a small battery once disconnected. By harnessing the battery-ch…
Universal energy fluctuations in inelastic scattering processes
Samuel L. Jacob, John Goold, Gabriel T. Landi +1
Quantum scattering is used ubiquitously in both experimental and theoretical physics across a wide range of disciplines, from high-energy physics to mesoscopic physics. In this wor…
System-bath correlations and finite-time operation enhance the efficiency of a dissipative quantum battery
Daniel Feliú, Felipe Barra
The reduced state of a small system strongly coupled to a thermal bath may be athermal and used as a small battery once disconnected. If the disconnecting process is too slow, the…
Laser powered dissipative quantum batteries in atom-cavity QED
Zamir Beleño, Marcelo F. Santos, Felipe Barra
The interaction of a three-level atom with the electromagnetic field of a quantum cavity in the presence of a laser field presents a rich behavior that we exploit to discuss two qu…
