It is tempting to speculate that such structures are forced into supercooled liquids by the frustrations inherent in the system and that the glass transition owes its origin to an underlying instability towards the disappearance of these structures. This model exhibits and entropy-vanishing transition where the string density vanishes. The last two animations describe the relaxation processes starting from an initial zero string density state, which is an ordered state. In all the graphics, the defects are the yellow triangles with two orientations. Fast spins are the filled red circles.
Strings are the clustering of the fast spins in vertical direction.
