Bohmian Mechanics with Discrete Operators
R. A. Hyman, Shane A. Caldwell, Edward Dalton
A deterministic Bohmian mechanics for operators with continuous and discrete spectra is presented. Randomness enters only through initial conditions. Operators with discrete spectr…

Thickness evolution of coercivity in ultrathin magnetic films
R. A. Hyman, A. Zangwill, M. D. Stiles
The thickness evolution of in-plane magnetization reversal in ultrathin films is studied with a theoretical model that takes account of surface roughness typical of epitaxial growt…
