Dear Thereza and Richard,

Elena has gone through all files (Origin and plain text) again and has collected the QMC data that we have, with a linked summary page: http://komet337.physik.uni-mainz.de/Gorelik/qmc_summary.html . Unfortunately, we still have no idea about the discretization dependence of the spin-spin correlation data and only a rough idea in the case of the double occupations. So will you send us additional data in the near future? Or shall we sort everything out during my stay in Davis?


You have probably seen the preprints on the thermodynamics of the Hubbard model near the Neel temperature recently put online by the Troyer and the Georges groups:

Thermodynamics of the three-dimensional Hubbard model: Implications for
cooling cold atomic gases in optical lattices

Attached is an extension of our DMFT-QMC comparison for the cubic lattice to the DCA and DMFT data shown in the former paper. I am pretty satisfied with it as the DCA data is roughly where an extrapolation of the QMC data might end up. Fortunately for us, they did not reach low enough temperatures to see the interesting signatures (except for U/t=8 where it is a bit subtle).

Best regards

Nils
