Controlled bit-flip of period-doubling and discrete time crystalline states in open systems
Roy D. Jara, Phatthamon Kongkhambut, Hans Keßler +2
In this work, we explore the robustness of a bit-flip operation against thermal and quantum noise for bits represented by the symmetry-broken pairs of the period-doubled (PD) state…
Observation of a phase transition from a continuous to a discrete time crystal
Phatthamon Kongkhambut, Jayson G. Cosme, Jim Skulte +4
Discrete (DTCs) and continuous time crystals (CTCs) are novel dynamical many-body states, that are characterized by robust self-sustained oscillations, emerging via spontaneous bre…
Enhancing exotic quantum fluctuations in a strongly entangled cavity BEC system
Leon Mixa, Hans Keßler, Andreas Hemmerich +1
We show that the strong coupling of a quantum light field and correlated quantum matter induces exotic quantum fluctuations in the matter sector. We determine their spectral charac…
Emergent limit cycles and time crystal dynamics in an atom-cavity system
Hans Keßler, Jayson G. Cosme, Michal Hemmerling +2
We propose an experimental realization of a time crystal using an atomic Bose-Einstein condensate in a high finesse optical cavity pumped with laser light detuned to the blue side…
