Application of Vibration-Transit Theory of Liquid Dynamics to the Brillouin Peak Dispersion Curve
Duane C. Wallace, Giulia De Lorenzi-Venneri, Eric D. Chisolm
The Brillouin peak appears in the dynamic structure factor S(q,w), and the dispersion curve is the Brillouin peak frequency as function of q. The theoretical function underlying S(…

New theoretical description of neutron scattering in a monatomic liquid
Duane C. Wallace, Giulia De Lorenzi-Venneri
In a recently developed theory of the atomic motion in monatomic liquids, the motion is comprised of normal mode vibrations in any of the large number of equivalent random valleys,…
