In a cluster crystal, each lattice site is occupied by multiple soft-core particles. As the number density is increased at zero temperature, a " cascade" of isostructural phase transitions can occur between states whose site...

We discuss the relationships between large deviations in stochastic systems, and “effective interactions” that induce particular rare events. We focus on the nature of these effective interactions in physical systems with...
