In equilibrium systems with short-ranged interactions, the relative stability of different thermodynamic states generally does not depend on system size (as long as this size is larger than the interaction range). Here, we use a large deviations approach to show that, in contrast, different states can exchange stability as system size is varied in a driven, bistable reaction-diffusion system. This striking effect is related to a shift from a spatially uniform to a nonuniform transition state…

Long Term Effects of Small Random Perturbations on Dynamical Systems: Theoretical and Computational Tools
The theoretical and computational aspects behind differential equations with multiplicative noise, Markov jump processes, and systems with fast and slow degrees of freedom are reviewed, and an algorithm that simplifies the geometric minimum action method to minimize the action in the space of arc-length parametrized curves is proposed.
Fluctuating hydrodynamics of multi-species reactive mixtures.
Good agreement with available theory demonstrates that the formulation is robust and a useful tool in the study of fluctuations in reactive multi-species fluids, and several problems with Langevin formulations of stochastic chemistry are identified.
Bistability: Requirements on Cell-Volume, Protein Diffusion, and Thermodynamics
It is shown that bistability requires fine-tuning towards small cell volumes (or compartments) and fast protein diffusion (well mixing) and hence may be restricted to small bacteria and eukaryotic nuclei, with switching triggered by volume changes during the cell cycle.
