Abstract
We present applications of a new Monte Carlo algorithm for the calcula tion of excited state energies of multi-dimensional quantum systems. T he method relies on computation of imaginary time correlation function s of appropriately chosen projection operators, followed by a numerica l inverse Laplace transformation performed with the maximum entropy me thod.
