Wetting Phase Transition at the Surface of Liquid Ga-Bi alloys: An X-ray Reflectivity Study
Holger Tostmann, Oleg Shpyrko, Peter S. Pershan +3
X-ray reflectivity measurements of the binary liquid Ga-Bi alloy reveal a dramatically different surface structure above and below the monotectic temperature …
Phase transitions as topology changes in configuration space: an exact result
Lapo Casetti, E. G. D. Cohen, Marco Pettini
The phase transition in the mean-field XY model is shown analytically to be related to a topological change in its configuration space. Such a topology change is completely describ…
Segregation of polydisperse granular media in the presence of a temperature gradient
S. Luding, O. Strauss, S. McNamara
Granular media are examined with the focus on polydisperse mixtures in the presence of two localized heat-baths. If the two driving energies are similar, the large particles prefer…
A Simple Method to Mix Granular Materials
S. McNamara, S. Luding
We show that a mixture of two species of granular particles with equal sizes but differing densities can be either segregated or mixed by adjusting the granular temperature gradien…
