Synchronization of Quasi-Particle Excitations in a Quantum Gas with Cavity-Mediated Interactions
Gabriele Natale, Alexander Baumgärtner, Justyna Stefaniak +5
Driven-dissipative quantum systems can undergo transitions from stationary to dynamical phases, reflecting the emergence of collective non-equilibrium behavior. We study such a tra…

Bandstructure of a coupled BEC-cavity system: effects of dissipation and geometry
David Baur, Simon Hertlein, Alexander Baumgärtner +4
We present a theoretical model for a transversally driven Bose-Einstein condensate coupled to an optical cavity. We focus on the interplay between different coherent couplings, whi…

Quantum theory for phonon lasing and non-classical state generation in mixed-species and single trapped ions
David Baur, Tanja Behrle, Ivan Rojkov +4
In this article we present a comprehensive theoretical investigation of phonon lasing with mixed-species trapped ions, as demonstrated in [T. Behrle, Phys. Rev. Lett. 131 (2023)],…
