# Systematically accelerated convergence of path integrals.

@article{Bogojevic2005SystematicallyAC, title={Systematically accelerated convergence of path integrals.}, author={Aleksandar Bogojevic and Antun Balaz and Aleksandar Belic}, journal={Physical review letters}, year={2005}, volume={94 18}, pages={ 180403 } }

We present a new analytical method that systematically improves the convergence of path integrals of a generic N-fold discretized theory. Using it we calculate the effective actions S(p) for p< or =9, which lead to the same continuum amplitudes as the starting action, but that converge to that continuum limit as 1/N(p). We checked this derived speedup in convergence by performing Monte Carlo simulations on several different models.

Numerical Investigation of the Cumulant Expansion for Fourier Path Integrals

- Mathematics, Computer Science
- PARA

The Helmholtz free energy of the model is calculated to demonstrate that recently derived approximate asymptotic expressions for the cumulants requiring only one-dimensional quadrature are both accurate and viable and expressions through third-cumulant order are significantly more rapidly convergent than either the primitive Fourier method or the partial average method.
