520 3 |a The mechanism of the B1-B2 reconstructive phase transition in KCl is elucidated by a combination of geometric modeling and path sampling molecular dynamics simulations. Even for the limited size of the simulation system collective movements of the ions are found to be disfavored. Instead, the phase transition is observed to be initiated by a small nucleus, which grows in the course of the transition process. Both phases are separated by an interface exhibiting a B33 structure.
