Density matrix algorithm for the calculation of dynamical properties of low dimensional systems
arXiv:cond-mat/9503094 · doi:10.1103/PhysRevB.52.R9827
Abstract
I extend the scope of the density matrix renormalization group technique developed by White to the calculation of dynamical correlation functions. As an application and performance evaluation I calculate the spin dynamics of the 1D Heisenberg chain.
