    "abstract": "Monte Carlo techniques have been widely employed in statistical physics as\nwell as in quantum theory in the Lagrangian formulation. However, in the\nconventional approach, it is extremely difficult to compute the excited states.\nHere we present a different algorithm: the Monte Carlo Hamiltonian method,\ndesigned to overcome the difficulties of the conventional approach. As a new\nexample, application to the Klein-Gordon field theory is shown.",
