Vacancy Formation Energy at High Pressures in Tantalum
Sonali Mukherjee, R. E. Cohen, Oguz Gulseren
We have computed the variation of the vacancy formation energy with pressure for Ta. Total energy calculations were performed for 16 and 54 atom supercells using a mixed basis pseu…
Scaling for vibrational modes of fractals tethered at the boundaries
Sonali Mukherjee, Hisao Nakanishi
Using a recently introduced mapping between a scalar elastic network tethered at its boundaries and a diffusion problem with permanent traps, we study various vibrational propertie…
Diffusion with critically correlated traps and the slow relaxation of the longest wavelength mode
Sonali Mukherjee, Hisao Nakanishi
We study diffusion on a substrate with permanent traps distributed with critical positional correlation, modeled by their placement on the perimeters of a critical percolation clus…
Markov chain analysis of random walks on disordered medium
Sonali Mukherjee, Hisao Nakanishi, Norman H. Fuchs
We study the dynamical exponents and for a particle diffusing in a disordered medium (modeled by a percolation cluster), from the regime of extreme disorder (i.e.,…
