This article describes recent technical developments that have made the total-energy pseudopotential the most powerful ab initio quantum-mechanical modeling method presently ava...
Iterative diagonalization of the Hamiltonian matrix is required to solve very large electronic-structure problems. Present algorithms are limited in their convergence rates at l...
Measurements show that single-mode waveguides can be constructed which have radiation losses of about 7 dB/km—very close to the intrinsic material scattering loss. These wavegui...

Silicon dioxide is fundamental in geology, in the electronic materials industry, and in the glass industry. We have carried out an ab initio total energy minimization study of t...
A 40-km length of optical fiber whose group-velocity dispersion decreases exponentially along its length has been fabricated. We experimentally compare the propagation of picose...
The electronic structures, adsorption geometries, chemisorption energies, and vibrational frequencies of single Cu and Ag atoms on Si(111) surfaces are determined by self-consis...
