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. 001037677 536__ $$0G:(DE-HGF)POF4-5111$$a5111 - Domain-Specific Simulation & Data Life Cycle Labs (SDLs) and Research Groups (POF4-511)$$cPOF4-511$$fPOF IV$$x0 001037677 536__ $$0G:(GEPRIS)196253076$$aDFG project G:(GEPRIS)196253076 - TRR 110: Symmetrien und Strukturbildung in der Quantenchromodynamik (196253076)$$c196253076$$x1 001037677 588__ $$aDataset connected to CrossRef Conference 001037677 7001_ $$0P:(DE-Juel1)188583$$aBerkowitz, Evan$$b1$$ufzj 001037677 7001_ $$0P:(DE-Juel1)159481$$aLuu, Tom$$b2$$ufzj 001037677 7001_ $$0P:(DE-HGF)0$$aOstmeyer, Johann$$b3 001037677 7001_ $$0P:(DE-Juel1)185942$$aRodekamp, Marcel$$b4$$ufzj 001037677 773__ $$a10.22323/1.453.0007 001037677 8564_ $$uhttps://juser.fz-juelich.de/record/1037677/files/LATTICE2023_007.pdf$$yOpenAccess 001037677 909CO $$ooai:juser.fz-juelich.de:1037677$$pdnbdelivery$$pdriver$$pVDB$$popen_access$$popenaire 001037677 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)165594$$aForschungszentrum Jülich$$b0$$kFZJ 001037677 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)188583$$aForschungszentrum Jülich$$b1$$kFZJ 001037677 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)159481$$aForschungszentrum Jülich$$b2$$kFZJ 001037677 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)185942$$aForschungszentrum Jülich$$b4$$kFZJ 001037677 9131_ $$0G:(DE-HGF)POF4-511$$1G:(DE-HGF)POF4-510$$2G:(DE-HGF)POF4-500$$3G:(DE-HGF)POF4$$4G:(DE-HGF)POF$$9G:(DE-HGF)POF4-5111$$aDE-HGF$$bKey Technologies$$lEngineering Digital Futures – Supercomputing, Data Management and Information Security for Knowledge and Action$$vEnabling Computational- & Data-Intensive Science and Engineering$$x0 001037677 9141_ $$y2024 001037677 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 001037677 915__ $$0LIC:(DE-HGF)CCBYNCND4$$2HGFVOC$$aCreative Commons Attribution-NonCommercial-NoDerivs CC BY-NC-ND 4.0 001037677 9201_ $$0I:(DE-Juel1)JSC-20090406$$kJSC$$lJülich Supercomputing Center$$x0 001037677 9201_ $$0I:(DE-Juel1)IAS-4-20090406$$kIAS-4$$lTheorie der Starken Wechselwirkung$$x1 001037677 980__ $$acontrib 001037677 980__ $$aVDB 001037677 980__ $$aUNRESTRICTED 001037677 980__ $$acontb 001037677 980__ $$aI:(DE-Juel1)JSC-20090406 001037677 980__ $$aI:(DE-Juel1)IAS-4-20090406 001037677 9801_ $$aFullTexts
