Metastability in the stochastic nearest-neighbor Kuramoto model of coupled phase oscillators
Nils Berglund, Georgi S. Medvedev, Gideon Simpson
The Kuramoto model (KM) of coupled phase-oscillators is analyzed in this work. The KM on a Cayley graph possesses a family of steady state solutions called twisted states. Topo…

The fast committor machine: Interpretable prediction with kernels
D. Aristoff, M. Johnson, G. Simpson +1
In the study of stochastic systems, the committor function describes the probability that a system starting from an initial configuration will reach a set before a set .…

RiteWeight: Randomized Iterative Trajectory Reweighting for Steady-State Distributions Without Discretization Error
Sagar Kania, Robert J. Webber, Gideon Simpson +2
A significant challenge in molecular dynamics (MD) simulations is ensuring that sampled configurations converge to the equilibrium or nonequilibrium stationary distribution of inte…
