Abstract The supersonic M× N-crowdions are excited in a two-dimensional lattice by giving
sufficiently large initial velocity v to the M× N block of atoms along a close-packed direction,
where N is the number of neighboring atoms in one close-packed row and M is the number
of neighboring rows. In this study, dynamics of a pair of quasi-1D supersonic 1× 2-crowdions
moving in parallel close-packed atomic rows separated by one non-excited atomic row
(middle row) are investigated in 2D triangular Morse lattice by means of molecular dynamics …
