Large anomalous shifts of potassium-39 Feshbach resonances
Ali Zaheer, Mohammed Bouras, Krzysztof Giergiel +3
We report the observation of large anomalous shifts, up to +7.5 G, of the positions of the 33.6 G and 39.9 G Feshbach resonances in potassium-39 atoms confined in a 1063.9 nm optic…
A Decade of Time Crystals: Quo Vadis?
Peter Hannaford, Krzysztof Sacha
Ten years ago, the new era of time crystals began. Time crystals are systems that behave in the time dimension like ordinary space crystals do in space dimensions. We present a bri…
Condensed matter physics in big discrete time crystals
Peter Hannaford, Krzysztof Sacha
We review the application of discrete time crystals created in a Bose-Einstein condensate (BEC) of ultracold atoms bouncing resonantly on an oscillating mirror to the investigation…
Discrete time crystals in Bose-Einstein Condensates and symmetry-breaking edge in a simple two-mode theory
Jia Wang, Krzysztof Sacha, Peter Hannaford +1
Discrete time crystals (DTCs) refer to a novel many-body steady state that spontaneously breaks the discrete time-translational symmetry in a periodically-driven quantum system. He…
Many-Body Effects and Quantum Fluctuations for Discrete Time Crystals in Bose-Einstein Condensates
Jia Wang, Peter Hannaford, Bryan J Dalton
We present a fully comprehensive multi-mode quantum treatment based on the truncated Wigner approximation (TWA) to study many-body effects and quantum fluctuations on the formation…
Creating big time crystals with ultracold atoms
Krzysztof Giergiel, Tien Tran, Ali Zaheer +4
We investigate the size of discrete time crystals s (ratio of response period to driving period) that can be created for a Bose-Einstein condensate (BEC) bouncing resonantly on an…
