Many-body out-of-equilibrium dynamics of hard-core lattice bosons with non-local loss (2014)
Journal Article
Everest, B., Hush, M., & Lesanovsky, I. (2014). Many-body out-of-equilibrium dynamics of hard-core lattice bosons with non-local loss. Physical Review B, 90(13), Article 134306. https://doi.org/10.1103/PhysRevB.90.134306

We explore the dynamics of hard-core lattice bosons in the presence of strong non-local particle loss. The evolution occurs on two distinct time-scales, first a rapid strongly correlated decay into a highly degenerate Zeno state subspace, followed by...

Out-of-equilibrium structures in strongly interacting Rydberg gases with dissipation (2014)
Journal Article

The nonequilibrium dynamics of a gas of cold atoms in which Rydberg states are off-resonantly excited is studied in the presence of noise. The interplay between interaction and off-resonant excitation leads to an initial dynamics where aggregates of...

Electromagnetically induced transparency in an entangled medium (2014)
Journal Article
Li, W., Viscor, D., Hofferberth, S., & Lesanovsky, I. (2014). Electromagnetically induced transparency in an entangled medium. Physical Review Letters, 112(24), https://doi.org/10.1103/PhysRevLett.112.243601

We theoretically investigate light propagation and electromagnetically induced transparency (EIT) in a quasi one-dimensional gas in which atoms interact strongly via exchange interactions. We focus on the case in which the gas is initially prepared i... Read More about Electromagnetically induced transparency in an entangled medium.

Steady-state properties of a driven atomic ensemble with nonlocal dissipation (2014)
Journal Article
Yu, D., Olmos, B., Lesanovsky, I., OLMOS SANCHEZ, B., & YU, D. (2014). Steady-state properties of a driven atomic ensemble with nonlocal dissipation. Physical Review A, 89(2), Article 023616. https://doi.org/10.1103/physreva.89.023616

In a driven dense ensemble of two-level atoms the decay acts in a correlated way on several atoms simultaneously. The competition between the coherent laser excitation and the dipole-dipole interaction induced by the dissipation gives rise to a bimod...

Generalized Dicke nonequilibrium dynamics in trapped ions (2014)
Journal Article
Genway, S., Li, W., Ates, C., Lanyon, B. P., & Lesanovsky, I. (2014). Generalized Dicke nonequilibrium dynamics in trapped ions. Physical Review Letters, 112(2), https://doi.org/10.1103/PhysRevLett.112.023603

We explore trapped ions as a setting to investigate nonequilibrium phases in a generalized Dicke model of dissipative spins coupled to phonon modes. We find a rich dynamical phase diagram including superradiantlike regimes, dynamical phase coexistenc... Read More about Generalized Dicke nonequilibrium dynamics in trapped ions.

Amplifying single impurities immersed in a gas of ultracold atoms (2011)
Journal Article
Olmos, B., Li, W., Hofferberth, S., & Lesanovsky, I. (2011). Amplifying single impurities immersed in a gas of ultracold atoms. Physical Review A, 84(4), Article 041607(R). https://doi.org/10.1103/PhysRevA.84.041607

We present a method for amplifying a single or scattered impurities immersed in a background gas of ultracold atoms so that they can be optically imaged and spatially resolved. Our approach relies on a Raman transfer between two stable atomic hyperfi... Read More about Amplifying single impurities immersed in a gas of ultracold atoms.

Towards rotation sensing with a single atomic clock
Presentation / Conference Contribution
Fernholz, T., Stevenson, R., Hush, M. R., Lesanovsky, I., Bishop, T., Gentile, F., Jammi, S., Pyragius, T., Bason, M. G., Mas, H., Pandey, S., Vasilakis, G., Poulios, K., & von Klitzing, W. Towards rotation sensing with a single atomic clock. Presented at SPIE Photonics Europe, Brussels, Belgium

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.
