Fluctuation-based evidence for number--phase dynamics in a frustrated orbital superfluid
Rui-Lang Zeng, Zi-Yao Zhang, Ling-Na Wu +5
Frustrated quantum matter can host intertwined orders rooted in symmetry-related low-energy landscapes, yet static order parameters alone do not reveal how fluctuations are organiz…
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 zero-energy excitation mode in the open Dicke model
Anton Bolian, Phatthamon Kongkhambut, Christoph Georges +6
Approaching phase boundaries in many-body systems can give rise to intriguing signatures in their excitation spectra. Here, we explore the excitation spectrum of a Bose-Einstein co…
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…
