computes and plots Kitaev Excitons spectra using exact diagonalization method
contains the main functions for solving the Kitaev Hamiltonian with holes and computing the spectral functions and absorption spectra.
plots absorption spectrum of a chain as
$V$ changing. Including the full spectrum and spatially resolved spectra at different sites.
plots absorption spectrum of a long chain as
$\tau$ changing. Including the full spectrum and spatially resolved spectra at different sites.
