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 …
Surface Structure of Liquid Metals and the Effect of Capillary Waves: X-ray Studies on Liquid Indium
Holger Tostmann, Oleg Shpyrko, Peter S. Pershan +3
We report x-ray reflectivity (XR) and small angle off-specular diffuse scattering (DS) measurements from the surface of liquid Indium close to its melting point of C. Fr…
Surface layering of liquids: The role of surface tension
Oleg Shpyrko, Masafumi Fukuto, Peter Pershan +4
Recent measurements show that the free surfaces of liquid metals and alloys are always layered, regardless of composition and surface tension; a result supported by three decades o…
Avoiding Infrared Catastrophes in Trapped Bose-Einstein Condensates
P. G. Kevrekidis, G. Theocharis, D. J. Frantzeskakis +1
This paper is concerned with the long wavelength instabilities (infrared catastrophes) occurring in Bose-Einstein condensates (BECs). We examine the modulational instability in ``c…
