«This model
exhibits no bulk thermodynamic -
phase transition, so one of the obstructions for reaching solutions present in previous models was eliminated,» he said.
Dr. Jerison studies systems governed by simple rules that nonetheless
exhibit complex behaviors, such as
phase transitions — for instance, when a slight temperature increase causes ice to melt into liquid water; and threshold phenomena — for instance, when a small extra deposit of soil causes a stable slope to topple over into a landslide.
The team found pentagons and fourfold pentilles, irregular pentagons with two different edge lengths,
exhibit a first - order solid - to - liquid
phase transition.
Systems with polygons of seven sides or more closely followed the melting behavior of hard disks, or circles,
exhibiting a continuous
phase transition from the solid to the hexatic
phase and a first - order
phase transition from the hexatic to the liquid
phase.
The results demonstrate that the grain boundaries within the entire misorientation range have multiple
phases and
exhibit structural
transitions, suggesting that
phase behavior of interfaces is likely a general phenomenon.
