Dear Nils,
I finished the dtau=0.0833 runs (still 8x8 lattices). I'm afraid
the Trotter errors seem to be shifting us away from your 0.025
minimum. Agreement would be worse after the extrapolation to
dtau=0. It's possible finite lattice size corrections woul
affect the results further. I will not do these at the present,
however, since I am not sure with what level of precision you really
want to do the comparison.
dtau 0.125 0.0833
Dmin 0.02512 0.02695
D(T=0) 0.03186 0.03501
