Role of thermal vibrations in phase transitions
T. R. S. Prasanna
All theoretical models (Heisenberg, Ising etc.) assume a negligible role for thermal vibrations in alloy and magnetic phase transitions. Analysis of diffraction data conclusively p…

Relation between ab initio molecular dynamics and electron-phonon interaction formalisms
T. R. S. Prasanna
The relation between ab initio molecular dynamics formalism and the electron-phonon interaction formalism [P.B. Allen and V. Heine, J. Phys. C 9, 2305 (1976)] is explored. The fund…
