Journal Article
Gillman, E., Carollo, F., & Lesanovsky, I. (2022). Asynchronism and nonequilibrium phase transitions in (1+1) -dimensional quantum cellular automata. Physical Review E, 106(3), Article L032103. https://doi.org/10.1103/PhysRevE.106.L032103

Probabilistic cellular automata provide a simple framework for exploring classical nonequilibrium processes. Recently, quantum cellular automata have been proposed that rely on the propagation of a one-dimensional quantum state along a fictitious dis...

Quantum and Classical Temporal Correlations in (1+1)D Quantum Cellular Automata (2021)
Journal Article

We employ (1 + 1)-dimensional quantum cellular automata to study the evolution of entangle-ment and coherence near criticality in quantum systems that display non-equilibrium steady-state phase transitions. This construction permits direct access to... Read More about Quantum and Classical Temporal Correlations in (1+1)D Quantum Cellular Automata.

Numerical simulation of quantum nonequilibrium phase transitions without finite-size effects (2021)
Journal Article

Classical (1 + 1)D cellular automata, as for instance Domany-Kinzel cellular automata, are paradigmatic systems for the study of non-equilibrium phenomena. Such systems evolve in discrete time-steps, and are thus free of time-discretisation errors. M...

Motivated by recent progress in the experimental development of quantum simulators based on Rydberg atoms, we introduce and investigate the dynamics of a class of (1+1)-dimensional quantum cellular automata. These non-equilibrium many-body models, wh... Read More about Nonequilibrium Phase Transitions in (1+1)-Dimensional Quantum Cellular Automata with Controllable Quantum Correlations.

The simulation of out-of-equilibrium dissipative quantum many body systems is a problem of fundamental interest to a number of fields in physics, ranging from condensed matter to cosmology. For unitary systems, tensor network methods have proved succ... Read More about Numerical Simulation of Critical Dissipative Non-Equilibrium Quantum Systems with an Absorbing State.

Critical behavior of the quantum contact process in one dimension (2019)
Journal Article

The contact process is a paradigmatic classical stochastic system displaying critical behavior even in one dimension. It features a non-equilibrium phase transition into an absorbing state that has been widely investigated and shown to belong to the...
