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…
Optical Bistability and Collective Behavior of Atoms trapped in a High-Q Ring Cavity
Th. Elsaesser, B. Nagorny, A. Hemmerich
We study the collective motion of atoms confined in an optical lattice operating inside a high finesse ring cavity. A simplified theoretical model for the dynamics of the system is…
Collective Atomic Motion in an Optical Lattice formed inside a High Finesse Cavity
B. Nagorny, Th. Elsaesser, A. Hemmerich
We report on collective non-linear dynamics in an optical lattice formed inside a high finesse ring cavity in a so far unexplored regime, where the light shift per photon times the…
Collective Sideband Cooling in an Optical Ring Cavity
Th. Elsaesser, B. Nagorny, A. Hemmerich
We propose a cavity based laser cooling and trapping scheme, providing tight confinement and cooling to very low temperatures, without degradation at high particle densities. A bid…
