Hexatic Phase Transition (VIDEO) DOE/Oak Ridge National Laboratory This video is under embargo. Please login to access this video. To view this video please enable JavaScript, and consider upgrading to a web browser that supports HTML5 video Caption A movie depicting the hexatic phase transition of a two-dimensional hard particle system of hexagons under external pressure. On the left, red and green particle pairs indicate the structure of defects in the system. On the right, blue and yellow particles show how defects migrate within the system, quickly hopping between sites and popping in and out of existence. University of Michigan researchers carried out a series of hard particle simulations on the Titan supercomputer to study how particle shape affects the physics of melting in two-dimensional systems.
