Quasiparticle Avalanche

Quasiparticle avalanche. A simulation starting from a perfect square lattice with an isolated pair quasiparticle (right-center). The pair propagates to the left while exciting an avalanche of pairs in a trailing Mach cone. Collisions among the excited pairs induce melting. White arrows denote velocity, and particle colors denote the distance between the two particles in each quasiparticle pair.
