Abstract
We reaccess the droplet condensation-evaporation transition of a three-dimensional Lennard-Jones system upon a temperature change. With the help of parallel multicanonical simulations we obtain precise estimates of the transition temperature and the width of the transition for systems with up to 2048 particles. This allows us to supplement previous observations of finite-size scaling regimes with a clearer picture also for the case of a continuous particle model.
Highlights
Despite the long-lasting scientific interest in droplet formation, it is still a modern problem with many open questions. This is partially due to the general nature of droplet formation, with relevance ranging from metastable decay over cloud formation to cluster formation in protein solutions
We consider equilibrium droplet formation which yields a firm basis to study the transition between a homogeneous gas and a mixed phase of a droplet in equilibrium with surrounding vapor [1, 2, 3, 4, 5]
The problem is formulated in the canonical ensemble
Summary
Despite the long-lasting scientific interest in droplet formation, it is still a modern problem with many open questions. We reaccess the droplet condensation-evaporation transition of a three-dimensional Lennard-Jones system upon a temperature change. This allows us to supplement previous observations of finite-size scaling regimes with a clearer picture for the case of a continuous particle model. One can fix the density and vary the temperature which yields an equivalent but “orthogonal” finite-size scaling behavior [12, 13].
