Description
A new approach to simulating lattice field theory with continuous fields is suggested and it is tested on φ4 field theory. Discrete variables are embedded into the field theory, so that large scale tunneling events can be induced via a modified Swendsen-Wang algorithm with fluctuating site-bond percolation probabilities. The measured dynamical critical exponents zED=0.07±0.07, 0.29±0.09, 0,87±0.20 in d=1, 2, 3 dimensions respectively are consistent with our conjecture that this embedded dynamics lies in the same universality class as the Swendsen-Wang Ising dynamics.
