Hybrid quantum/classical modeling of material systems : the learn on the fly molecular dynamics scheme. Moras, G., Choudhury, R., Kermode, J. R., Csanyi, G., Payne, M. C., & Vita, A. D. In Trends in Computational Nanomechanics : Transcending Length and Time Scales, volume Volume 9, pages 1–23. Springer, November, 2010. Paper abstract bibtex The atomistic simulation of many processes in materials involves large-size model systems where different levels of complexity need to be described simultaneously. While accurate quantum mechanical simulations of large-size systems are usually not affordable, less computationally intensive classical models are not suitable for the description of many chemical processes. Hybrid (quantum/classical) modelling schemes are required in these circumstances. Here, we describe the ?Learn on the fly? (LOTF) hybrid molecular dynamics scheme. Some technical aspects of this technique are illustrated through a series of examples of its applications to multiscale processes in silicon
