The Shape of Melting in Two Dimensions

https://vimeo.com/201923842 Snow falls in winter and melts in spring, but what drives the phase change in between? Although melting is a familiar phenomenon encountered in everyday life, playing a part in many industrial and commercial processes, much remains to be discovered about this transformation at a fundamental level. In 2015,…
