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…
