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 about Epidemic dynamics in open quantum spin systems.

Facilitation dynamics and localization phenomena in Rydberg lattice gases with position disorder (2017)
Journal Article
Marcuzzi, M., Minář, J., Barredo, D., Léséleuc, S. D., Labuhn, H., Lahaye, T., …Lesanovsky, I. (2017). Facilitation dynamics and localization phenomena in Rydberg lattice gases with position disorder. Physical Review Letters, 118(6-10), Article 063606. https://doi.org/10.1103/PhysRevLett.118.063606

We explore the dynamics of Rydberg excitations in an optical tweezer array under anti-blockade (or facilitation) conditions. Due to the finite temperature the atomic positions are randomly spread, an effect that leads to quenched correlated disorder...

Nonequilibrium effective field theory for absorbing state phase transitions in driven open quantum spin systems (2017)
Journal Article
Buchhold, M., Everest, B., Marcuzzi, M., Lesanovsky, I., & Diehl, S. (2017). Nonequilibrium effective field theory for absorbing state phase transitions in driven open quantum spin systems. Physical Review B, 95, https://doi.org/10.1103/PhysRevB.95.014308

Phase transitions to absorbing states are among the simplest examples of critical phenomena out of equilibrium. The characteristic feature of these models is the presence of a fluctuationless configuration which the dynamics cannot leave, which has p...

Prethermalization from a low-density Holstein-Primakoff expansion (2016)
Journal Article

We consider the non-equilibrium dynamics arising after a quench of the transverse magnetic field of a quantum Ising chain, together with the sudden switch-on of a long-range interaction term. The dynamics after the quantum quench is mapped onto a ful... Read More about Prethermalization from a low-density Holstein-Primakoff expansion.

Emergent kinetic constraints, ergodicity breaking, and cooperative dynamics in noisy quantum systems (2016)
Journal Article

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...

Absorbing state phase transition with competing quantum and classical fluctuations (2016)
Journal Article

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...

Non-equilibrium universality in the dynamics of dissipative cold atomic gases (2015)
Journal Article

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.

Universal nonequilibrium properties of dissipative rydberg gases (2014)
Journal Article

© 2014 American Physical Society. We investigate the out-of-equilibrium behavior of a dissipative gas of Rydberg atoms that features a dynamical transition between two stationary states characterized by different excitation densities. We determine th... Read More about Universal nonequilibrium properties of dissipative rydberg gases.

We investigate the evolution of interacting Rydberg gases in the limit of strong noise and dissipation. Starting from a description in terms of a Markovian quantum master equation we derive effective equations of motion that govern the dynamics on a...

We revisit here the problem of the collective non-equilibrium dynamics of a classical statistical system at a critical point and in the presence of surfaces. The effects of breaking separately space- and time-translational invariance are well underst... Read More about Critical relaxation and the combined effects of spatial and temporal boundaries.
