Friedel oscillations in the force constants of metals

Physical Review B, 1997
Analytic expressions are derived for the long-range falloff of the force constants of nearly-free-electron metals. Comparison with exact results shows that Friedel oscillations dominate the force constants of fcc Al beyond the fourth-neighbor shell. Applications suggested include improving embedding theories of defect-related strain, improving methods ...

On the Constants of Motion for the Time-Dependent Oscillator

Europhysics Letters (EPL), 1986
We apply recent results on symmetries of equations of motion and equivalent Lagrangians in order to obtain the constants of motion and auxiliary conditions for the time-dependent oscillator.
