Compressed Wannier modes found from an regularized energy functional
Farzin Barekat, Ke Yin, Russel E. Caflisch +3
We propose a method for calculating Wannier functions of periodic solids directly from a modified variational principle for the energy, subject to the requirement that the Wannier…
Anisotropic step stiffness from a kinetic model of epitaxial growth
Dionisios Margetis, Russel E. Caflisch
Starting from a detailed model for the kinetics of a step edge or island boundary, we derive a Gibbs-Thomson type formula and the associated step stiffness as a function of the ste…
Level Set Approach to Reversible Epitaxial Growth
M. Petersen, C. Ratsch, R. E. Caflisch +1
We generalize the level set approach to model epitaxial growth to include thermal detachment of atoms from island edges. This means that islands do not always grow and island disso…
