Fast Coherent Splitting of Bose-Einstein Condensates
Yevhenii Kuriatnikov, Nikolaus Würkner, Karthikeyan Kumaran +6
Preparation of non-trivial quantum states without introducing unwanted excitations or decoherence remains a central challenge in utilizing ultracold atomic systems for quantum simu…
Quantum-limited generalized measurement for tunnel-coupled condensates
Maximilian Prüfer, Yuri Minoguchi, Tiantian Zhang +3
The efficient readout of the relevant information is pivotal for quantum simulation experiments. Often only single observables are accessed by performing standard projective measur…
Squeezing oscillations in a multimode bosonic Josephson junction
Tiantian Zhang, Mira Maiwöger, Filippo Borselli +3
Quantum simulators built from ultracold atoms promise to study quantum phenomena in interacting many-body systems. However, it remains a challenge to experimentally prepare strongl…
Optimizing optical potentials with physics-inspired learning algorithms
Martino Calzavara, Yevhenii Kuriatnikov, Andreas Deutschmann-Olek +6
We present our new experimental and theoretical framework which combines a broadband superluminescent diode (SLED/SLD) with fast learning algorithms to provide speed and accuracy i…
Phase slips driven by acoustic waves in Bose-Einstein condensates with ring topology
Y. Kuriatnikov, A. Olashyn, A. I. Yakimenko
Rotational superradiance is one of the most fascinating phenomena in black-hole physics. Here, with the aim of probing quantum properties of superradiance in the lab, we investigat…
Spatiotemporal vortex rings in atomic Bose-Einstein condensates
O. G. Chelpanova, Y. I. Kuriatnikov, S. Vilchinskii +1
We investigate spatiotemporal vortex rings with phase dislocation both in space and time. It is demonstrated that these structures naturally appear as a periodical in time edge pha…
Stochastic phase slips in toroidal Bose-Einstein condensates
Kyrylo Snizhko, Karyna Isaieva, Yevhenii Kuriatnikov +3
Motivated by recent experiments we study the influence of thermal noise on the phase slips in toroidal Bose-Einstein condensates with a rotating weak link. We derive a generalized…
Generation and decay of persistent current in a toroidal Bose-Einstein condensate
A. I. Yakimenko, S. I. Vilchinskii, Y. M. Bidasyuk +3
Persistent current, or "flow without friction", as well as quantum vortices are the hallmarks of superfluidity. Recently a very long-lived persistent flow of atoms has been experim…
Vortices in a toroidal Bose-Einstein condensate with a rotating weak link
A. I. Yakimenko, Y. M. Bidasyuk, M. Weyrauch +2
Motivated by a recent experiment [K.C. Wright et. al. Phys. Rev. Lett. 110, 025302 (2013)], we investigate deterministic discontinuous jumps between quantized circulation states in…
