Nucleation in phase separation

Absence of a trapping effect on the kinetic critical radius in nucleation and growth processes

This is my take on an issue brought up by Erdélyi et al., Acta Mat. 58, 5639 (2010), who claimed that the critical nucleus size, which is conventionally modelled only in terms of thermodynamic quantities, can vary by orders of magnitude because of dynamical effects. I show that their results cannot be reproduced by simulating exactly the same system, and that the trapping effect, which they invoke to explain their results, both contradicts thermodynamics and is impossible to happen in the simulated model, as it would violate detailed balance.
