We perform a series of molecular dynamics simulations in a binary Lennard-Jones system at temperatures close to its mode-coupling temperature, Tc. We demonstrate that the string-like movements carried out by a fraction of the particles are of ballistic nature. Depending on temperature these...

In this work we investigate by means of molecular dynamics simulations the detailed time evolution of string-like cooperative motions in a binary Lennard–Jones system at temperatures close to its mode-coupling temperature, Tc. The strings will be fully geometrically and dynamically...
