Large deviations in the presence of cooperativity and slow dynamics
Stephen Whitelam
We study simple models of intermittency, involving switching between two states, within the dynamical large-deviation formalism. Singularities appear in the formalism when switchin…
Sampling rare fluctuations of discrete-time Markov chains
Stephen Whitelam
We describe a simple method that can be used to sample the rare fluctuations of discrete-time Markov chains. We focus on the case of Markov chains with well-defined steady-state me…
Phase separation and large deviations of lattice active matter
Stephen Whitelam, Katherine Klymko, Dibyendu Mandal
Off-lattice active Brownian particles form clusters and undergo phase separation even in the absence of attractions or velocity-alignment mechanisms. Arguments that explain this ph…
Irregular model DNA particles self-assemble into a regular structure
Zdenek Preisler, Barbara Sacca, Stephen Whitelam
DNA nanoparticles with three-fold coordination have been observed to self-assemble in experiment into a network equivalent to the hexagonal (6.6.6) tiling, and a network equivalent…
Rare behavior of growth processes via umbrella sampling of trajectories
Katherine Klymko, Phillip L. Geissler, Juan P. Garrahan +1
We compute probability distributions of trajectory observables for reversible and irreversible growth processes. These results reveal a correspondence between reversible and irreve…
