Accelerated relaxation and suppressed dynamic heterogeneity in a kinetically constrained (East) model with swaps (2019)
Journal Article
Gutiérrez, R., Garrahan, J. P., & Jack, R. L. (2019). Accelerated relaxation and suppressed dynamic heterogeneity in a kinetically constrained (East) model with swaps. Journal of Statistical Mechanics: Theory and Experiment, 2019(9), Article 094006. https://doi.org/10.1088/1742-5468/ab39d8

We introduce a kinetically constrained spin model with a local softness parameter, such that spin flips can violate the kinetic constraint with an (annealed) site-dependent rate. We show that adding MC swap moves to this model can dramatically accele...

Strong zero modes in a class of generalized Ising spin ladders with plaquette interactions (2019)
Journal Article
Vasiloiu, L. M., Carollo, F., Marcuzzi, M., & Garrahan, J. P. (2019). Strong zero modes in a class of generalized Ising spin ladders with plaquette interactions. Physical Review B, 100(2), Article 024309. https://doi.org/10.1103/physrevb.100.024309

© 2019 American Physical Society. We study a class of spin-1/2 quantum ladder models with generalized plaquette interactions in the presence of a transverse field. We show that in certain parameter regimes, these models have strong zero modes respons... Read More about Strong zero modes in a class of generalized Ising spin ladders with plaquette interactions.

Unraveling the large deviation statistics of Markovian open quantum systems (2019)
Journal Article
Carollo, F., Jack, R. L., & Garrahan, J. P. (2019). Unraveling the large deviation statistics of Markovian open quantum systems. Physical Review Letters, 122(13), Article 130605. https://doi.org/10.1103/physrevlett.122.130605

We analyze dynamical large deviations of quantum trajectories in Markovian open quantum systems in their full generality. We derive a quantum level-2.5 large deviation principle for these systems, which describes the joint fluctuations of time-averag...

Quantum accelerated approach to the thermal state of classical all-to-all connected spin systems with applications to pattern retrieval in the Hopfield neural network (2019)
Journal Article
Fiorelli, E., Rotondo, P., Marcuzzi, M., Garrahan, J. P., & Lesanovsky, I. (2019). Quantum accelerated approach to the thermal state of classical all-to-all connected spin systems with applications to pattern retrieval in the Hopfield neural network. Physical Review A, 99(3), Article 032126. https://doi.org/10.1103/physreva.99.032126

We explore the question as to whether quantum effects can yield a speedup of the nonequilibrium evolution of fully connected quadratic spin models towards a classical thermal state. In our approach we exploit the fact that the thermal state of a spin...
