Robustness of many-body localization in the presence of dissipation (2016)
Journal Article

Many-body localization (MBL) has emerged as a novel paradigm for robust ergodicity breaking in closed quantum many-body systems. However, it is not yet clear to which extent MBL survives in the presence of dissipative processes induced by the couplin...

Signatures of many-body localisation in a system without disorder and the relation to a glass transition (2016)
Journal Article

We study a quantum spin system—adapted from a facilitated spin model for classical glasses—with local bilinear interactions and without quenched disorder which seems to display characteristic signatures of a many-body localisation (MBL) transition. F... Read More about Signatures of many-body localisation in a system without disorder and the relation to a glass transition.

Experimental observation of controllable kinetic constraints in a cold atomic gas (2016)
Journal Article

Many-body systems relaxing to equilibrium can exhibit complex dynamics even if their steady state is trivial. In situations where relaxation requires highly constrained local particle rearrangements, such as in glassy systems, this dynamics can be di...

Emergence of cooperative dynamics in fully packed classical dimers (2016)
Journal Article

We study the behavior of classical dimer coverings of the square lattice—a paradigmatic model for systems subject to constraints—evolving under local stochastic dynamics, by means of Monte Carlo simulations and theoretical arguments. We observe clear... Read More about Emergence of cooperative dynamics in fully packed classical dimers.

Dynamical phase transitions as a resource for quantum enhanced metrology (2016)
Journal Article

We consider the general problem of estimating an unknown control parameter of an open quantum system. We establish a direct relation between the evolution of both system and environment and the precision with which the parameter can be estimated. We...

Phase transition for quenched coupled replicas in a plaquette spin model of glasses (2016)
Journal Article

We study a three-dimensional plaquette spin model whose low temperature dynamics is glassy, due to localized defects and effective kinetic constraints. The thermodynamics of this system is smooth at all temperatures. We show that coupling it to a sec...

Self-similar non-equilibrium dynamics of a many-body system with power-law interactions (2015)
Journal Article

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.

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.

Emergent Rhombus Tilings from Molecular Interactions with M-fold Rotational Symmetry (2015)
Journal Article

© 2015 American Physical Society. We show that model molecules with particular rotational symmetries can self-assemble into network structures equivalent to rhombus tilings. This assembly happens in an emergent way, in the sense that molecules sponta... Read More about Emergent Rhombus Tilings from Molecular Interactions with M-fold Rotational Symmetry.

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.

Out-of-equilibrium evolution of kinetically constrained many-body quantum systems under purely dissipative dynamics (2014)
Journal Article

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...

Common Physical Framework Explains Phase Behavior and Dynamics of Atomic, Molecular, and Polymeric Network Formers (2014)
Journal Article

We show that the self-assembly of a diverse collection of building blocks can be understood within a common physical framework. These building blocks, which form periodic honeycomb networks and nonperiodic variants thereof, range in size from atoms t...
