Dynamical criticality in open systems: nonperturbative physics, microscopic origin, and direct observation (2018)
Journal Article
Pérez-Espigares, C., Carollo, F., Garrahan, J. P., & Hurtado, P. I. (2018). Dynamical criticality in open systems: nonperturbative physics, microscopic origin, and direct observation. Physical Review E, 98(6), Article 060102(R). https://doi.org/10.1103/physreve.98.060102

Driven diffusive systems may undergo phase transitions to sustain atypical values of the current. This leads in some cases to symmetry-broken space-time trajectories which enhance the probability of such fluctuations. Here, we shed light on both the...

Enhancing correlation times for edge spins through dissipation (2018)
Journal Article
Vasiloiu, L. M., Carollo, F., & Garrahan, J. P. (2018). Enhancing correlation times for edge spins through dissipation. Physical Review B, 98(9), 1-6. https://doi.org/10.1103/physrevb.98.094308

Spin chains with open boundaries, such as the transverse field Ising model, can display coherence times for edge spins that diverge with the system size as a consequence of almost conserved operators, the so-called strong zero modes. Here we discuss... Read More about Enhancing correlation times for edge spins through dissipation.

Current fluctuations in boundary-driven quantum spin chains (2018)
Journal Article
Carollo, F., Garrahan, J. P., & Lesanovsky, I. (2018). Current fluctuations in boundary-driven quantum spin chains. Physical Review B, 98(9), 1-9. https://doi.org/10.1103/physrevb.98.094301

Boundary-driven quantum spin chains are paradigmatic nonequilibrium systems featuring the presence of particle currents. In general, it may not be possible to distinguish an incoherent type of particle transport from a truly quantum coherent one thro...

Making rare events typical in Markovian open quantum systems (2018)
Journal Article
Carollo, F., Garrahan, J. P., Lesanovsky, I., & Pérez-Espigares, C. (2018). Making rare events typical in Markovian open quantum systems. Physical Review A, 98(1), Article 010103. https://doi.org/10.1103/physreva.98.010103

Large dynamical fluctuations—atypical realizations of the dynamics sustained over long periods of time—can play a fundamental role in determining the properties of collective behavior of both classical and quantum nonequilibrium systems. Rare dynamic... Read More about Making rare events typical in Markovian open quantum systems.

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.
