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…
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…
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…
Two-colour laser cooling for 40K-87Rb quantum gas mixtures
Yann Kiefer, Max Hachmann, Andreas Hemmerich
We present an efficient cooling scheme for fermionic atoms, using laser light red and blue detuned with respect to the and principle…
