Hi
I ran some simulations using the worm-algorithm for softcore bosons (Nmax = 2) on the kagome for determining the MI-SF transition. I get convergent results (3x3, 6x6, 9x9 lattices) and a just-ok scaling law (with 600000 sweeps and 150000 thermalization); my understanding is that there should be no sign-problem for this algorithm on this model. Can someone confirm this, or must I experiment with the sweeps and thermalization?
Thanks, Vipin
