Self-similar non-equilibrium dynamics of a many-body system with power-law interactions (2015)
Journal Article
Gutierrez, R., Garrahan, J. P., & Lesanovsky, I. (2015). Self-similar non-equilibrium dynamics of a many-body system with power-law interactions. Physical Review E, 92(6), Article e062144. https://doi.org/10.1103/PhysRevE.92.062144

The influence of power-law interactions on the dynamics of many-body systems far from equilibrium is much less explored than their effect on static and thermodynamic properties. To gain insight into this problem we introduce and analyze here an out-o... Read More about Self-similar non-equilibrium dynamics of a many-body system with power-law interactions.

Emergent devil's staircase without particle-hole symmetry in Rydberg quantum gases with competing attractive and repulsive interactions (2015)
Journal Article
Lan, Z., Minář, J., Levi, E., Li, W., & Lesanovsky, I. (2015). Emergent devil's staircase without particle-hole symmetry in Rydberg quantum gases with competing attractive and repulsive interactions. Physical Review Letters, 115, Article 203001. https://doi.org/10.1103/PhysRevLett.115.203001

The devil's staircase is a fractal structure that characterizes the ground state of one-dimensional classical lattice gases with long-range repulsive convex interactions. Its plateaus mark regions of stability for specific filling fractions which are...

Coherence in a cold atom photon transistor (2015)
Journal Article

Recent experiments have realized an all-optical photon transistor using a cold atomic gas. This approach relies on electromagnetically induced transparency (EIT) in conjunction with the strong interaction among atoms excited to high-lying Rydberg sta...

© 2015 American Physical Society. © 2015 American Physical Society. The Sagnac effect enables interferometric measurements of rotation with high precision. Using matter waves instead of light promises resolution enhancement by orders of magnitude tha... Read More about Sagnac Interferometry with a Single Atomic Clock.

Non-equilibrium universality in the dynamics of dissipative cold atomic gases (2015)
Journal Article
Marcuzzi, M., Levi, E., Li, W., Garrahan, J. P., Olmos, B., & Lesanovsky, I. (2015). Non-equilibrium universality in the dynamics of dissipative cold atomic gases. New Journal of Physics, 17(July), Article 72003. https://doi.org/10.1088/1367-2630/17/7/072003

The theory of continuous phase transitions predicts the universal collective properties of a physical system near a critical point, which for instance manifest in characteristic power-law behaviours of physical observables. The well-established conce... Read More about Non-equilibrium universality in the dynamics of dissipative cold atomic gases.

Dynamic Nuclear Polarization as Kinetically Constrained Diffusion (2015)
Journal Article
Köckenberger, W., Wiśniewski, D., Karabanov, A., Wiśniewski, D., Lesanovsky, I., & Köckenberger, W. (2015). Dynamic Nuclear Polarization as Kinetically Constrained Diffusion. Physical Review Letters, 115(2), Article 020404. https://doi.org/10.1103/physrevlett.115.020404

Dynamic nuclear polarization (DNP) is a promising strategy for generating a significantly increased nonthermal spin polarization in nuclear magnetic resonance (NMR) and its applications that range from medicine diagnostics to material science. Being... Read More about Dynamic Nuclear Polarization as Kinetically Constrained Diffusion.

Spin correlations as a probe of quantum synchronization in trapped ion phonon-lasers (2015)
Journal Article
Hush, M. R., Li, W., Genway, S., Lesanovsky, I., & Armour, A. (2015). Spin correlations as a probe of quantum synchronization in trapped ion phonon-lasers. Physical Review A, 91, Article 061401. https://doi.org/10.1103/PhysRevA.91.061401

We investigate quantum synchronization theoretically in a system consisting of two cold ions in microtraps. The ions' motion is damped by a standing-wave laser whilst also being driven by a blue-detuned laser which results in self-oscillation. Workin...

Strongly correlated growth of Rydberg aggregates in a vapor cell (2015)
Journal Article
Urvoy, A., Ripka, F., Lesanovsky, I., Booth, D., Shaffer, J., Pfau, T., & Löw, R. (2015). Strongly correlated growth of Rydberg aggregates in a vapor cell. Physical Review Letters, 114, Article 203002. https://doi.org/10.1103/PhysRevLett.114.203002

The observation of strongly interacting many-body phenomena in atomic gases typically requires ultracold samples. Here we show that the strong interaction potentials between Rydberg atoms enable the observation of many-body effects in an atomic vapor...
