Vitrification vs. Crystalization


The most basic difference between the glass forming (vitrification) process and the crystallization may be seen in the figure on the left. Vitrification is actually not really a transition , because it does not involve any genuinely singular behaviors, in contrast with crystallization. A very likely implication is that, vitrification should not be due to a critical mode that features long-range correlations. Its dynamics should be essentially local, like what happens to a traffic congestion.

Casimir force between two sheets of graphene

I had thought about this sometime ago but did not come up with the calculations on this problem, basically i did not get time to do that. Now i'm glad that some people have done this. See the following:

Supersolid in history

Supersolid has been a fascinating conception since its inception. However, the experimental aspects are still not conclusive, as reviewed by Thouless in his private note:

This website collects plenty of information of American scientists who have been working in US since 1945 to present. http://www.aip.org/history/acap/

How SSC came into being

Here is an article accounting the history of Solid State Communications. I'm interested in such stuff basically because I'm concerned with how should a practicing scientist regard the platforms fostering their communications.
