Observation of Brownian Motion of a Bose-Einstein Condensate
Xiao-Qiong Wang, Rui-Lang Zeng, Zi-Yao Zhang +4
We report on the experimental observation of classical Brownian motion in momentum space by a Bose-Einstein condensate (BEC) of Rubidium atoms prepared in a hexagonal optical latti…
Torus bifurcation of a dissipative time crystal
Jayson G. Cosme, Phatthamon Kongkhambut, Anton Bölian +5
Using a quantum gas setup consisting of a Bose-Einstein condensate strongly coupled to a high-finesse optical cavity by a transverse pump laser, we experimentally observe an instab…
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…
Realizing limit cycles in dissipative bosonic systems
Jim Skulte, Phatthamon Kongkhambut, Hans Keßler +3
We propose a general mechanism for generating limit cycle (LC) oscillations by coupling a linear bosonic mode to a dissipative nonlinear bosonic mode. By analyzing the stability ma…
