Abstract:We review our recently developed electronic structure calculation methods for the dynamics of large-scale solids, liquids or soft materials with an efficient algorithm of linear algebra. The Hamiltonian of electronic structures is based on the 'atomic superposition and electron delocalization molecular orbitals theory' (ASED), using the Mulliken charge density. Very crucial algorithms of the linear algebra are the generalized Lanczos method and the generalized shifted COCG (conjugate orthogonal conjugate gradi… Show more
