We present a detailed investigation of the wave vector dependence of collective atomic motion in Au49Cu26.9Si16.3Ag5.5Pd2.3 and Pd42.5Cu27Ni9.5P21 supercooled liquids close to the glass transition temperature. Using x-ray photon correlation spectrosc

We present a simple extension of the semi-classical model for a two-level system in a cavity, in order to incorporate multiple polarized transitions, such as those appearing in neutral and charged quantum dots (QDs), and two nondegenerate linearly po

Report

Liquid-liquid transition revealed by quasi-static cooling of an ultra-viscous metallic liquid

Autor: Hechler, S., Ruta, B., Stolpe, M., Pineda, E., Evenson, Z., Gross, O., Hembree, W., Bernasconi, A., Busch, R., Gallino, I.

Publikováno v: Phys. Rev. Materials 2, 085603 (2018)

Temperature-driven polyamorphism has been reported in various supercooled liquids and glasses. The dynamical and structural routes followed by the system during such crossovers are however not universal and appear to be related to intrinsic kinetic p
