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…
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…
Pauli crystal superradiance
Daniel Ortuño-Gonzalez, Rui Lin, Justyna Stefaniak +4
Pauli crystals are unique geometric structures of non-interacting fermions, resembling crystals, that emerge solely from Fermi statistics and confinement. Unlike genuine quantum cr…
