My research group and I are conducting interdisciplinary research activities at the intersection between advanced mathematical techniques, parallel numerical algorithms, and computational nanosciences. We aim at addressing the fundamental problems of accuracy, robustness and parallel scalability in large-scale first-principle electronic calculations with applications ranging from quantum chemistry and material sciences, to solid-state electronics and nanotechnology. The significant challenges posed by such realistic quantum simulations applied to large-scale atomistic systems, have motivated the development of two new HPC algorithms and their implementation on parallel architectures: (i) the SPIKE banded system solver, and (ii) the FEAST eigensolver.
