On-site interactions in quantum thermal machines: efficiency, rectification and entanglement beyond local and global master equations
Salvatore Araceli, Teddy H. M. Ong, Baptiste Debecker +4
Advances in experimental techniques have opened new routes for harnessing non-equilibrium dynamics in mesoscopic quantum systems. In this context, we study the impact of on-site in…
Phase-dependent role of dissipation across the Aubry-André-Harper transition
Gerardo Suárez, Baptiste Debecker, Francesco Cosco +4
We study transport across the Aubry-André-Harper localization transition in the presence of non-Markovian dissipation. For a single particle initially at the center of the chain,…
Symmetric Resourceful Steady States via Non-Markovian Dissipation
Baptiste Debecker, Eduardo Serrano-Ensástiga, Thierry Bastin +2
We prove a no-go theorem for symmetry-based dissipative engineering of collective-spin steady states: in spin-only Lindblad dynamics with jump operators linear in the collective-sp…
The role of non-Markovian dissipation in quantum phase transitions: tricriticality, spin squeezing, and directional symmetry breaking
Baptiste Debecker, Lukas Pausch, Jonathan Louvet +3
Understanding how to control phase transitions in quantum systems is at the forefront of research for the development of new quantum materials and technologies. Here, we study how…
Spectral theory of non-Markovian dissipative phase transitions
Baptiste Debecker, John Martin, François Damanet
Dissipative phase transitions in quantum systems have been largely studied under the so-called Markovian approximation, where the environments to which the systems are coupled are…
Controlling Matter Phases beyond Markov
Baptiste Debecker, John Martin, François Damanet
Controlling phase transitions in quantum systems via coupling to reservoirs has been mostly studied for idealized memory-less environments under the so-called Markov approximation.…
