Anderson and many-body localization in the presence of spatially correlated classical noise (2022)
Journal Article
Marcantoni, S., Carollo, F., Gambetta, F. M., Lesanovsky, I., Schneider, U., & Garrahan, J. P. (2022). Anderson and many-body localization in the presence of spatially correlated classical noise. Physical Review B, 106(13), Article 134211. https://doi.org/10.1103/physrevb.106.134211

We study the effect of spatially correlated classical noise on both Anderson and many-body localization of a disordered fermionic chain. By analyzing the evolution of the particle density imbalance following a quench from an initial charge density wa...

Slow dynamics and large deviations in classical stochastic Fredkin chains (2022)
Journal Article
Causer, L., Garrahan, J. P., & Lamacraft, A. (2022). Slow dynamics and large deviations in classical stochastic Fredkin chains. Physical Review E, 106(1), Article 014128. https://doi.org/10.1103/PhysRevE.106.014128

The Fredkin spin chain serves as an interesting theoretical example of a quantum Hamiltonian whose ground state exhibits a phase transition between three distinct phases, one of which violates the area law. Here we consider a classical stochastic ver... Read More about Slow dynamics and large deviations in classical stochastic Fredkin chains.

Random matrix theory for quantum and classical metastability in local Liouvillians (2022)
Journal Article
Li, J. L., Rose, D. C., Garrahan, J. P., & Luitz, D. J. (2022). Random matrix theory for quantum and classical metastability in local Liouvillians. Physical Review B, 105(18), Article L180201. https://doi.org/10.1103/physrevb.105.l180201

We consider the effects of strong dissipation in quantum systems with a notion of locality, which induces a hierarchy of many-body relaxation timescales as shown in [Phys. Rev. Lett. 124, 100604 (2020)]. If the strength of the dissipation varies stro... Read More about Random matrix theory for quantum and classical metastability in local Liouvillians.

Hierarchical classical metastability in an open quantum East model (2022)
Journal Article
Rose, D. C., MacIeszczak, K., Lesanovsky, I., & Garrahan, J. P. (2022). Hierarchical classical metastability in an open quantum East model. Physical Review E, 105(4), Article 044121. https://doi.org/10.1103/PhysRevE.105.044121

We study in detail an open quantum generalization of a classical kinetically constrained model - the East model - known to exhibit slow glassy dynamics stemming from a complex hierarchy of metastable states with distinct lifetimes. Using the recently... Read More about Hierarchical classical metastability in an open quantum East model.

Exact solution of the "rule 150" reversible cellular automaton (2022)
Journal Article
Wilkinson, J. W., Prosen, T., & Garrahan, J. P. (2022). Exact solution of the "rule 150" reversible cellular automaton. Physical Review E, 105(3), Article 034124. https://doi.org/10.1103/PhysRevE.105.034124

We study the dynamics and statistics of the Rule 150 reversible cellular automaton (RCA). This is a one-dimensional lattice system of binary variables with synchronous (Floquet) dynamics that corresponds to a bulk deterministic and reversible discret...

Finite time large deviations via matrix product states (2022)
Journal Article

Recent work has shown the effectiveness of tensor network methods for computing large deviation functions in constrained stochastic models in the infinite time limit. Here we show that these methods can also be used to study the statistics of dynamic... Read More about Finite time large deviations via matrix product states.
