RENORMALIZATION GROUP METHOD FOR VIBRATIONAL BEHAVIOR IN MIXED CRYSTALS
D. Schmeltzer et R. BesermanSolid State Institute and Physics Department, Technion - Israel Institute of Technology, Haifa, Israel
Abstract
The renormalization group method has been applied to investigate vibrational properties of a diatomic mixed crystal. It has been found that there exists a fixed point which separates the one mode behavior from the two mode behavior. This transition depends on concentration, force constants and mass ratios.
