Animated sequence of snapshots from a molecular dynamics simulation of laser melting
This animation illustrates the competition between the heterogeneous and homogeneous melting mechanisms in a 20 nm Au film irradiated by a 200 fs laser pulse at an absorbed fluence of 55 J/m2.
Atoms are colored according to the local order parameter - blue atoms have local crystalline surroundings, red atoms belong to the liquid phase.
