Query: Finite Lattice Hamiltonian Computations in the P-Representation: the
  Schwinger Model   The Schwinger model is studied in a finite lattice by means of the
P-representation. The vacuum energy, mass gap and chiral condensate are
evaluated showing good agreement with the expected values in the continuum
limit.
