Model Hessian for accelerating first-principles structure optimizations
M. V. Fernandez-Serra, Emilio Artacho, Jose. M. Soler
We present two methods to accelerate first-principles structural relaxations, both based on the dynamical matrix obtained from a universal model of springs for bond stretching and…
