Hardening by softening in a flow of chainlike self-driven objects

Mashiko, Takashi; Imanishi, Yasuhito; Kuwajima, Ryota; … - In: Physica A: Statistical Mechanics and its Applications 388 (2009) 15, pp. 3202-3212

A two-dimensional square lattice system, on which flexible, chainlike, self-driven objects move randomly but are drifted to a same direction, causing a unidirectional net flow, is investigated by numerical simulations. It is shown that the objects exhibit a freezing transition from a smoothly...
