A New Numerical Algorithm for the Analytic Continuation of Green's Functions
The need to calculate the spectral properties of a Hermitian operatorHfrequently arises in the technical sciences. A common approach to its solution involves the construction of the Green's function operatorG(z) = [z−H]−1in the complexzplane. For example, the energy spectrum and other physical...
