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(…

A Mean Atom Trajectory Model for Monatomic Liquids
Eric D. Chisolm, Duane C. Wallace
A recent description of the motion of atoms in a classical monatomic system in liquid and supercooled liquid states divides the motion into two parts: oscillations within a given m…

Velocity Autocorrelation and Harmonic Motion in Supercooled Nondiffusing Monatomic Liquids
Eric D. Chisolm, Brad E. Clements, Duane C. Wallace
Studies of the many-body potential surface of liquid sodium have shown that it consists of a great many intersecting nearly harmonic valleys, a large fraction of which have the sam…
