First-principles study of the energetics of charge and cation mixing in U_{1-x} Ce_x O_2
B. E. Hanken, C. R. Stanek, N. Grønbech-Jensen +1
The formalism of electronic density-functional-theory, with Hubbard-U corrections (DFT+U), is employed in a computational study of the energetics of U_{1-x} Ce_x O_2 mixtures. The…
Collective Multi-Vortex States in Periodic Arrays of Traps
Charles Reichhardt, Niels Gronbech-Jensen
We examine the vortex states in a 2D superconductor interacting with a square array of pinning sites. As a function of pinning size or strength we find a series of novel phases inc…
The Effect of Splayed Pins on Vortex Creep and Critical Currents
C. J. Olson, R. T. Scalettar, G. T. Zimanyi
We study the effects of splayed columnar pins on the vortex motion using realistic London Langevin simulations. At low currents vortex creep is strongly suppressed, whereas the cri…
Statistical mechanics of a nonlinear discrete system
K. Ø. Rasmussen, T. Cretegny, P. G. Kevrekidis +1
Statistical mechanics of the discrete nonlinear Schrödinger equation is studied by means of analytical and numerical techniques. The lower bound of the Hamiltonian permits the cons…
Theoretical and Experimental Adsorption Studies of Polyelectrolytes on an Oppositely Charged Surface
R. Jay Mashl, Niels Grønbech-Jensen, M. R. Fitzsimmons +2
Using self-assembly techniques, x-ray reflectivity measurements, and computer simulations, we study the effective interaction between charged polymer rods and surfaces. Long-time B…
A phenomenological electronic stopping power model for molecular dynamics and Monte Carlo simulation of ion implantation into silicon
David Cai, Niels Gronbech-Jensen, Charles M. Snell +1
It is crucial to have a good phenomenological model of electronic stopping power for modeling the physics of ion implantation into crystalline silicon. In the spirit of the Brandt-…
