Coexistence of long- and quasi-long range spatial order in 1D quantum quasicrystals
A. Mendoza-Coto, M. Grossklags, J. Stefaniak +2
Quasicrystals exhibit long-range positional order without periodicity, arising from multiple incommensurate wave vectors. In self-assembled quasicrystals, the spontaneous breaking…
Master Equation for a Quantum Gas of Polarizable Particles in Cavities
Tom Schmit, Catalin-Mihai Halati, Tobias Donner +2
Quantum gases of atoms and molecules in optical cavities offer a formidable laboratory for studying the out-of-equilibrium dynamics of open quantum systems with long-range interact…
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…
Stability and decay of subradiant patterns in a quantum gas with photon-mediated interactions
Alexander Baumgärtner, Simon Hertlein, Tom Schmit +5
Metastability and its relaxation mechanisms challenge our understanding of the stability of quantum many-body systems, revealing a gap between the microscopic dynamics of the indiv…
Laser-painted cavity-mediated interactions in a quantum gas
Mariano Bonifacio, Francesco Piazza, Tobias Donner
Experimental platforms based on ultracold atomic gases have significantly advanced the quantum simulation of complex systems, yet the exploration of phenomena driven by long-range…
