Glassy dynamics due to a trajectory phase transition in dissipative Rydberg gases (2018)
Journal Article
Pérez-Espigares, C., Lesanovsky, I., Garrahan, J. P., & Gutiérrez, R. (2018). Glassy dynamics due to a trajectory phase transition in dissipative Rydberg gases. Physical Review A, 98(2), doi:10.1103/physreva.98.021804. ISSN 2469-9926

The physics of highly excited Rydberg atoms is governed by blockade or exclusion interactions that hinder the excitation of atoms in the proximity of a previously excited one. This leads to cooperative effects and a relaxation dynamics displaying spa... Read More

Quench dynamics of a dissipative Rydberg gas in the classical and quantum regimes (2018)
Journal Article
Gribben, D., Lesanovsky, I., & Gutierrez, R. (in press). Quench dynamics of a dissipative Rydberg gas in the classical and quantum regimes. Physical Review A, 97(1), doi:10.1103/PhysRevA.97.011603. ISSN 2469-9926

Understanding the non-equilibrium behavior of quantum systems is a major goal of contemporary physics. Much research is currently focused on the dynamics of many-body systems in lowdimensional lattices following a quench, i.e., a sudden change of par... Read More

Epidemic dynamics in open quantum spin systems (2017)
Journal Article
Perez-Espigares, C., Marcuzzi, M., Gutierrez, R., & Lesanovsky, I. (2017). Epidemic dynamics in open quantum spin systems. Physical Review Letters, 119(14), doi:10.1103/PhysRevLett.119.140401. ISSN 0031-9007

We explore the non-equilibrium evolution and stationary states of an open many-body system which displays epidemic spreading dynamics in a classical and a quantum regime. Our study is motivated by recent experiments conducted in strongly interacting... Read More

Non-equilibrium fluctuations and metastability arising from non-additive interactions in dissipative multi-component Rydberg gases (2016)
Journal Article
Gutierrez, R., Garrahan, J. P., & Lesanovsky, I. (2016). Non-equilibrium fluctuations and metastability arising from non-additive interactions in dissipative multi-component Rydberg gases. New Journal of Physics, 18, doi:10.1088/1367-2630/18/9/093054. ISSN 1367-2630

We study the out-of-equilibrium dynamics of dissipative gases of atoms excited to two or more high-lying Rydberg states. This situation bears interesting similarities to classical binary (in general p-ary) mixtures of particles. The effective forces... Read More

Quantum non-equilibrium dynamics of Rydberg gases in the presence of dephasing noise of different strengths (2016)
Journal Article
Levi, E., Gutierrez, R., & Lesanovsky, I. (2016). Quantum non-equilibrium dynamics of Rydberg gases in the presence of dephasing noise of different strengths. Journal of Physics B: Atomic, Molecular and Optical Physics, 49(18), doi:10.1088/0953-4075/49/18/184003. ISSN 0953-4075

In the presence of strong dephasing noise the dynamics of Rydberg gases becomes effectively classical, due to the rapid decay of quantum superpositions between atomic levels. Recently a great deal of attention has been devoted to the stochastic dynam... Read More

Front propagation versus bulk relaxation in the annealing dynamics of a kinetically constrained model of ultrastable glasses (2016)
Journal Article
Gutierrez, R., & Garrahan, J. P. (in press). Front propagation versus bulk relaxation in the annealing dynamics of a kinetically constrained model of ultrastable glasses. Journal of Statistical Mechanics: Theory and Experiment, 2016, doi:10.1088/1742-5468/2016/07/074005. ISSN 1742-5468

Glasses prepared by physical vapour deposition have been shown to be remarkably more stable than those prepared by standard cooling protocols, with properties that appear to be similar to systems aged for extremely long times. When subjected to a rap... Read More
