  text: Bosonic field theories may be formulated in terms of stochastic differential
    equations. The characteristic long term behaviour of these systems is a decay
    into the global minimum of their Hamiltonian. If local minima exist, the rate
    of this decay is determined by instanton effects. We calculate the decay rate
    and perform computer simulations on a 1 + 1 dimensional model to test the instanton
    approximation. We find the instanton approximations to be in very good agreement
    with the simulation results.
