Dear everybody,
I am curious I it is possible to write a function in ALPS ED code to calculate the dynamical responses in a spectral representation ?
It seems like in a simplest case one can compute it directly by having access to the matrix elements of the operator and corresponding energy eigenvalues of the Hamiltonian. Isn't it ?
Will be thankful for the answer!
With best regards,
Mykola
