Emergent kinetic constraints, ergodicity breaking, and cooperative dynamics in noisy quantum systems (2016)
Journal Article
Everest, B., Marcuzzi, M., Garrahan, J. P., & Lesanovsky, I. (2016). Emergent kinetic constraints, ergodicity breaking, and cooperative dynamics in noisy quantum systems. Physical Review E, 94(5), Article 052108. https://doi.org/10.1103/physreve.94.052108

Kinetically constrained spin systems play an important role in understanding key properties of the dynamics of slowly relaxing materials, such as glasses. Recent experimental studies have revealed that manifest kinetic constraints govern the evolutio...

Superfluid flow past an obstacle in annular Bose-Einstein condensates (2016)
Journal Article
Syafwan, M., Kevrekidis, P., Paris-Mandoki, A., Lesanovsky, I., Kruger, P., Hackermuller, L., & Susanto, H. (2016). Superfluid flow past an obstacle in annular Bose-Einstein condensates. Journal of Physics B: Atomic, Molecular and Optical Physics, 49(23), 1-8. https://doi.org/10.1088/0953-4075/49/23/235301

© 2016 IOP Publishing Ltd. We investigate the flow of a one-dimensional nonlinear Schrödinger model with periodic boundary conditions past an obstacle, motivated by recent experiments with Bose-Einstein condensates in ring traps. Above certain rotati... Read More about Superfluid flow past an obstacle in annular Bose-Einstein condensates.

Enhancement of Rydberg-mediated single-photon nonlinearities by electrically tuned Förster resonances (2016)
Journal Article
Gorniaczyk, H., Tresp, C., Bienias, P., Paris-Mandoki, A., Li, W., Mirgorodskiy, I., …Hofferberth, S. (2016). Enhancement of Rydberg-mediated single-photon nonlinearities by electrically tuned Förster resonances. Nature Communications, 7, Article e12480. https://doi.org/10.1038/ncomms12480

We demonstrate experimentally that Stark-tuned Förster resonances can be used to substantially increase the interaction between individual photons mediated by Rydberg interaction inside an optical medium. This technique is employed to boost the gain... Read More about Enhancement of Rydberg-mediated single-photon nonlinearities by electrically tuned Förster resonances.

Absorbing state phase transition with competing quantum and classical fluctuations (2016)
Journal Article
Marcuzzi, M., Buchhold, M., Diehl, S., & Lesanovsky, I. (2016). Absorbing state phase transition with competing quantum and classical fluctuations. Physical Review Letters, 116(24), https://doi.org/10.1103/PhysRevLett.116.245701

Stochastic processes with absorbing states feature examples of non-equilibrium universal phenomena. While the classical regime has been thoroughly investigated in the past, relatively little is known about the behavior of these non-equilibrium system...

Towards rotation sensing with a single atomic clock (2016)
Presentation / Conference Contribution
Fernholz, T., Stevenson, R., Hush, M. R., Lesanovsky, I., Bishop, T., Gentile, F., …von Klitzing, W. (2016). Towards rotation sensing with a single atomic clock. Proceedings of SPIE, 9900(990007), https://doi.org/10.1117/12.2229878

We discuss a scheme to implement a gyroscopic atom sensor with magnetically trapped ultra-cold atoms. Unlike standard light or matter wave Sagnac interferometers no free wave propagation is used. Interferometer operation is controlled only with stati... Read More about Towards rotation sensing with a single atomic clock.

Experimental observation of controllable kinetic constraints in a cold atomic gas (2016)
Journal Article
Valado, M., Simonelli, C., Hoogerland, M., Lesanovsky, I., Garrahan, J. P., Arimondo, E., …Morsch, O. (2016). Experimental observation of controllable kinetic constraints in a cold atomic gas. Physical Review A, 93(4), Article 040701. https://doi.org/10.1103/PhysRevA.93.040701

Many-body systems relaxing to equilibrium can exhibit complex dynamics even if their steady state is trivial. In situations where relaxation requires highly constrained local particle rearrangements, such as in glassy systems, this dynamics can be di...
