One solution is to solve Schrodinger equation using time dependent variational principle (TDVP) with matrix product states (MPSs) proposed by Haegeman el al. [Physical Review B 94, 165116], and Fourier transform correlation functions in time to frequency domain. Another way is to directly compute the transition rate between the ground state and several low lying momentum eigenstates that are accessed using MPSs method amended with momentum filtering process.
