✦ Synopsis

We construct an effective Hamiltonian via Monte Carlo from a given action. This Hamiltonian describes physics in the Ž low energy regime. We test it by computing spectrum, wave functions and thermodynamical observables average energy . and specific heat for the free system and the harmonic oscillator. The method is shown to work also for other local potentials.

We present a new way to compute thermodynamical observables on the lattice. We compute excited states and thermodynamical functions in the scalar model via the Monte Carlo Hamiltonian technique. We find agreement with standard Lagrangian lattice calculations, but observe lesser fluctuations in the r
