# Systematic speedup of path integrals of a generic N-fold discretized theory

@article{Bogojevic2005SystematicSO, title={Systematic speedup of path integrals of a generic N-fold discretized theory}, author={Aleksandar Bogojevic and Antun Balaz and Aleksandar Belic}, journal={Physical Review B}, year={2005}, volume={72}, pages={064302} }

We present and discuss a detailed derivation of an analytical method that systematically improves the convergence of path integrals of a generic N-fold discretized theory. We develop an explicit procedure for calculating a set of effective actions S{sup (p)}, for p=1,2,3,... which have the property that they lead to the same continuum amplitudes as the starting action, but converge to that continuum limit ever faster. Discretized amplitudes calculated using the p-level effective action differ… Expand
