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…
Been Down So Long it Looks Like Up to Me: A Unified Derivation of Conjugate Gradient and Variable Metric Minimization
R. A. Hyman, Bridget Doporcyk, John Tetzlaff
Simple derivations, at a level appropriate for an undergraduate computational physics course, of the most popular methods for finding the minimum of a function of many variables ar…
Comment on ``Density Matrix Renormalization Group Study of the Haldane Phase in Random One-Dimensional Antiferromagnets"
Kun Yang, R. A. Hyman
In a recent Letter (PRL 83, 3297 (1999)), Hida presented numerical results indicating that the Haldane phase of the Heisenberg antiferromagnetic spin-1 chain is stable against bond…
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…
Magnetic Reversal on Vicinal Surfaces
R. A. Hyman, A. Zangwill, M. D. Stiles
We present a theoretical study of in-plane magnetization reversal for vicinal ultrathin films using a one-dimensional micromagnetic model with nearest-neighbor exchange, four-fold…
An Impurity Driven Phase Transition in the Antiferromagnetic Spin-1 Chain
R. A. Hyman, Kun Yang
Using an asymptotically exact real space renormalization procedure, we find that the Heisenberg antiferromagnetic spin-1 chain undergoes an impurity driven second order phase trans…
