摘要:We present some new results regarding simulations of nite density QCD based on a canonical
approach. A previous study has shown that such simulations are feasible, at least on small lattices.
In the current study, we investigate some of the issues left open: we study the errors introduced by
our approximation of the action and we show how to tune it to reduce the cost of the simulations
while keeping the errors under control. To further reduce the cost of the simulations, we check
the reliability of reweighting method with respect to the baryon number. Finally, using these
optimizations, we carry out the simulations at larger densities than in our previous study to look
for signals of a phase transition.
