Signatures of Associative Memory Behavior in a Multimode Dicke Model (2020)
Journal Article
Fiorelli, E., Marcuzzi, M., Rotondo, P., Carollo, F., & Lesanovsky, I. (2020). Signatures of Associative Memory Behavior in a Multimode Dicke Model. Physical Review Letters, 125(7), https://doi.org/10.1103/physrevlett.125.070604

© 2020 American Physical Society. Dicke-like models can describe a variety of physical systems, such as atoms in a cavity or vibrating ion chains. In equilibrium these systems often feature a radical change in their behavior when switching from weak... Read More about Signatures of Associative Memory Behavior in a Multimode Dicke Model.

Dynamics of strongly coupled disordered dissipative spin-boson systems (2020)
Journal Article
Fiorelli, E., Rotondo, P., Carollo, F., Marcuzzi, M., & Lesanovsky, I. (2020). Dynamics of strongly coupled disordered dissipative spin-boson systems. Physical Review Research, 2(1), https://doi.org/10.1103/physrevresearch.2.013198

Spin-boson Hamiltonians are an effective description for numerous quantum few-and many-body systems such as atoms coupled to cavity modes, quantum electrodynamics in circuits and trapped ion systems. While reaching the limit of strong coupling is pos... Read More about Dynamics of strongly coupled disordered dissipative spin-boson systems.

Classical stochastic discrete time crystals (2019)
Journal Article
Gambetta, F. M., Carollo, F., Lazarides, A., Lesanovsky, I., & Garrahan, J. P. (2019). Classical stochastic discrete time crystals. Physical Review E, 100(6), Article 060105(R). https://doi.org/10.1103/PhysRevE.100.060105

© 2019 American Physical Society. We describe a general and simple paradigm for discrete time crystals (DTCs), systems with a stable subharmonic response to an external driving field, in a classical thermal setting. We consider, specifically, an Isin... Read More about Classical stochastic discrete time crystals.

Numerical Simulation of Critical Dissipative Non-Equilibrium Quantum Systems with an Absorbing State (2019)
Journal Article
Gillman, E., Carollo, F., & Lesanovsky, I. (2019). Numerical Simulation of Critical Dissipative Non-Equilibrium Quantum Systems with an Absorbing State. New Journal of Physics, 21, Article 093064. https://doi.org/10.1088/1367-2630/ab43b0

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
Carollo, F., Gillman, E., Weimer, H., & Lesanovsky, I. (2019). Critical behavior of the quantum contact process in one dimension. Physical Review Letters, 123(10), https://doi.org/10.1103/PhysRevLett.123.100604

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...

Quantum spin chain dissipative mean-field dynamics (2018)
Journal Article
Benatti, F., Carollo, F., Floreanini, R., & Narnhofer, H. (2018). Quantum spin chain dissipative mean-field dynamics. Journal of Physics A: Mathematical and Theoretical, 51(32), https://doi.org/10.1088/1751-8121/aacbdb

We study the emergent dynamics resulting from the infinite volume limit of the mean-field dissipative dynamics of quantum spin chains with clustering, but not time-invariant states. We focus upon three algebras of spin operators: the commutative alge... Read More about Quantum spin chain dissipative mean-field dynamics.

Fluctuating hydrodynamics, current fluctuations and hyperuniformity in boundary-driven open quantum chains (2017)
Journal Article
Carollo, F., Garrahan, J. P., Lesanovsky, I., & Pérez-Espigares, C. (2017). Fluctuating hydrodynamics, current fluctuations and hyperuniformity in boundary-driven open quantum chains. Physical Review E, 96(5), Article 052118. https://doi.org/10.1103/PhysRevE.96.052118

We consider a class of either fermionic or bosonic non-interacting open quantum chains driven by dissipative interactions at the boundaries and study the interplay of coherent transport and dissipative processes, such as bulk dephasing and diffusion....
