Identification and optimal control strategies for the transversal splitting of ultra--cold Bose gases
Nikolaus Würkner, Yevhenii Kuriatnikov, Karthikeyan Kumaran +5
Splitting a Bose--Einstein condensate (BEC) is a key operation in fundamental physics experiments and emerging quantum technologies, where precise preparation of well--defined init…
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…
Stable vortex in Bose-Einstein condensate dark matter
Y. O. Nikolaieva, A. O. Olashyn, Y. I. Kuriatnikov +2
The nature of dark matter (DM) is one of the most fascinating unresolved challenges of modern physics. One of the perspective hypotheses suggests that DM consists of ultralight bos…
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…
