Multigrid solution of a path integral formulation for the hydrogen atom
Dov Bai
An efficient multigrid Monte-Carlo algorithm for calculating the ground state of the hydrogen atom using path integral is presented. The algorithm uses a unigrid approach. The acti…

Multiscale Computation of a Polypeptide Backbone Model
Dov Bai
The multiscale Monte-Carlo algorithm outlined in Bai and Brandt[1] is applied to a simple model of the polypeptide backbone. Effective coarse level Hamiltonians are derived by a fa…
