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…
