Abstract

Zero-temperature dynamical spectra for Hubbard lattices and simple atoms are obtained using ground state projection quantum Monte Carlo and the maximum entropy method. Once zero-temperature imaginary-time correlations are identified and calculated, maximum entropy deconvolutions produce results of similar quality as those obtained from finite temperature quantum Monte Carlo for which this method has been frequently employed.
