SYSTEMATIC SPEEDUP OF ENERGY SPECTRA CALCULATIONS FOR MANY-BODY SYSTEMS

We present an application of a recently developed method for accelerated Monte Carlo computations of path integrals to the problem of energy spectra calculation of generic many-particle systems. We calculate the energy spectra of a two-particle two dimensional system in a quartic potential using the hierarchy of discretized effective actions, and demonstrate agreement with analytical results governing the increase in efficiency of the new method.
