T-structured fluid and jamming in driven Brownian rotators
Institut für Theoretische Physik II, Heinrich-Heine-Universität Düsseldorf Universitätsstrasse 1, 40225 Düsseldorf, Germany
Accepted: 4 November 2004
The dynamics of two-dimensional suspensions of Brownian rods which are driven by an external torque are explored by computer simulation and instability theory. For increasing density the system self-organizes into a “T-structured fluid”, where neighbouring rods preferentially orient perpendicular to each other until an overlap density is reached. Then a sharp jamming transition occurs towards a dynamically blocked state with parallel neighbouring rods.
