Generalized optimal paths and weight distributions revealed through the large deviations of random walks on networks
Ricardo Gutiérrez, Carlos Pérez-Espigares
Numerous problems of both theoretical and practical interest are related to finding shortest (or otherwise optimal) paths in networks, frequently in the presence of some obstacles…
Accelerated relaxation and suppressed dynamic heterogeneity in a kinetically constrained (East) model with swaps
Ricardo Gutierrez, Juan P. Garrahan, Robert L. Jack
We introduce a kinetically constrained spin model with a local softness parameter, such that spin flips can violate the kinetic constraint with an (annealed) site-dependent rate. W…
Physical swap dynamics, shortcuts to relaxation and entropy production in dissipative Rydberg gases
Ricardo Gutiérrez, Juan P. Garrahan, Igor Lesanovsky
Dense Rydberg gases are out-of-equilibrium systems where strong density-density interactions give rise to effective kinetic constraints. They cause dynamic arrest associated with h…
Quench dynamics of a dissipative Rydberg gas in the classical and quantum regime
Dominic Gribben, Igor Lesanovsky, Ricardo Gutierrez
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 lo…
Epidemic dynamics in open quantum spin systems
Carlos Pérez-Espigares, Matteo Marcuzzi, Ricardo Gutiérrez +1
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…
Experimental signatures of an absorbing-state phase transition in an open driven many-body quantum system
Ricardo Gutierrez, Cristiano Simonelli, Matteo Archimi +6
Understanding and probing phase transitions in non-equilibrium systems is an ongoing challenge in physics. A particular instance are phase transitions that occur between a non-fluc…
Front propagation versus bulk relaxation in the annealing dynamics of a kinetically constrained model of ultrastable glasses
Ricardo Gutierrez, Juan P. Garrahan
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 sim…
Non-equilibrium fluctuations and metastability arising from non-additive interactions in dissipative multi-component Rydberg gases
Ricardo Gutierrez, Juan P. Garrahan, Igor Lesanovsky
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…
Quantum non-equilibrium dynamics of Rydberg gases in the presence of dephasing noise of different strengths
Emanuele Levi, Ricardo Gutierrez, Igor Lesanovsky
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. Recen…
Self-similar non-equilibrium dynamics of a many-body system with power-law interactions
Ricardo Gutiérrez, Juan P. Garrahan, Igor Lesanovsky
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…
The Glass Transition in Fluids with Magnetic Interactions
Ricardo Gutierrez, Bhaskar Sen Gupta, Itamar Procaccia
We study the glass transition in fluids where particles are endowed with spins, such that magnetic and positional degrees of freedom are coupled. Novel results for slowing down in…
