Catching and reversing quantum jumps and thermodynamics of quantum trajectories (2018)
Journal Article
Garrahan, J. P., & Guta, M. (2018). Catching and reversing quantum jumps and thermodynamics of quantum trajectories. Physical Review A, 98(5), Article 052137. https://doi.org/10.1103/PhysRevA.98.052137

A recent experiment by Minev et. al [arXiv:1803.00545] demonstrated that in a dissipative (artificial) 3-level atom with strongly intermittent dynamics it is possible to " catch and reverse " a quantum jump " mid-flight " : by the conditional applica...

Phases of quantum dimers from ensembles of classical stochastic trajectories (2018)
Journal Article
Oakes, T., Powell, S., Castelnovo, C., Lamacraft, A., & Garrahan, J. P. (2018). Phases of quantum dimers from ensembles of classical stochastic trajectories. Physical Review B, 98(6), Article 064302. https://doi.org/10.1103/PhysRevB.98.064302

We study the connection between the phase behaviour of quantum dimers and the dynamics of classical stochastic dimers. At the so-called Rokhsar–Kivelson (RK) point a quantum dimer Hamiltonian is equivalent to the Markov generator of the dynamics of c...

Solvation in space-time: pre-transition effects in trajectory space (2018)
Journal Article
Katira, S., Garrahan, J. P., & Mandadapu, K. K. (2018). Solvation in space-time: pre-transition effects in trajectory space. Physical Review Letters, 120(26), https://doi.org/10.1103/PhysRevLett.120.260602

We demonstrate pre-transition effects in space--time in trajectories of systems in which the dynamics displays a first-order phase transition between distinct dynamical phases. These effects are analogous to those observed for thermodynamic first-ord... Read More about Solvation in space-time: pre-transition effects in trajectory space.

Rare behavior of growth processes via umbrella sampling of trajectories (2018)
Journal Article
Klymko, K., Geissler, P. L., Garrahan, J. P., & Whitelam, S. (2018). Rare behavior of growth processes via umbrella sampling of trajectories. Physical Review E, 97(3), https://doi.org/10.1103/PhysRevE.97.032123

We compute probability distributions of trajectory observables for reversible and irreversible growth processes. These results reveal a correspondence between reversible and irreversible processes, at particular points in parameter space, in terms of...
