An alternative implementation of the Lanczos algorithm for wave function propagation
Quanlin Jie, Dunhuan Liu
We reformulate the Lanczos algorithm for quantum wave function propagation in terms of variational principle. By including some basis states of previous time steps into the variati…

Modified conjugated gradient method for diagonalising large matrices
Quanlin Jie, Dunhuan Liu
We present an iterative method to diagonalise large matrices. The basic idea is the same as the conjugated gradient (CG) method, i.e, minimizing the Rayleigh quotient via its gradi…
