520 _ _ |a We apply constant imaginary offsets to the path integral for a reduction of the sign problem in theHubbard model. These simple transformations enhance the quality of results from HMCcalculations without compromising the speed of the algorithm. This method enables us to efficientlycalculate systems that are otherwise inaccessible due to a severe sign problem. To support this claim,we present observables of the C20 and C60 fullerenes. Furthermore, we demonstrate that at a certainoffset, the sign problem is completely lifted in the limit of large chemical potential.
