Anharmonic self energies of phonons in silicon

Narasimhan, Shobhana; Vanderbilt, David (American Physical Society, 1991-02-15)

We have carried out a realistic ab initio calculation of the contribution of cubic anharmonicity to the inverse lifetime GAMMA and the frequency shift DELTA of phonons in silicon. The cubic coupling constants for phonons ...
Elastic-Stress Domains and the Herringbone Reconstruction on Au(111)

Narasimhan, Shobhana; Vanderbilt, David (American Physical Society, 1992-09-07)

We suggest that the herringbone reconstruction of the Au(111) surface results from the spontaneous formation of "stress domains." The surface is described theoretically by a 2D Frenkel-Kontorova model. Upon including ...
