A Numerical Study of Renormalization Group Transformations on Multiscale Lattices
We propose a new updating scheme to perform constrained hybrid Monte Carlo on lattices with different scales. Starting from a coarse lattice, the scheme preserves the long distance physics and the evolution fills in the short distance physics on the fine lattice. Methods of tuning lattice parameters to follow the renormalization group transformation are explored. With this scheme we expect to reduce the cost of generating fine lattice configurations with charm quark.
