The usefulness of this "Brillouin operator" in practical applications is explored by studying the scaling of pseudoscalar decay constants in quenched QCD, with rather good results in the physical charm region. We also investigate the suitability of this operator as a kernel to the overlap procedure. Here, the resulting overlap operator is found to be cheaper to construct and significantly better localized than the variety with the standard Wilson kernel. 000018056 536__ $$0G:(DE-Juel1)FUEK411$$2G:(DE-HGF)$$aScientific Computing (FUEK411)$$cFUEK411$$x0 000018056 536__ $$0G:(DE-HGF)POF2-411$$a411 - Computational Science and Mathematical Methods (POF2-411)$$cPOF2-411$$fPOF II$$x1 000018056 542__ $$2Crossref$$i2011-06-21$$uhttp://link.aps.org/licenses/aps-default-license 000018056 588__ $$aDataset connected to Web of Science 000018056 650_7 $$2WoSType$$aJ 000018056 7001_ $$0P:(DE-Juel1)VDB102942$$aKoutsou, G.$$b1$$uFZJ 000018056 77318 $$2Crossref$$3journal-article$$a10.1103/physrevd.83.114512$$b : American Physical Society (APS), 2011-06-21$$n11$$p114512$$tPhysical Review D$$v83$$x1550-7998$$y2011 000018056 773__ $$0PERI:(DE-600)2844732-3$$a10.1103/PhysRevD.83.114512$$gVol. 83, p. 114512$$n11$$p114512$$q83<114512$$tPhysical review / D$$v83$$x1550-7998$$y2011 000018056 8567_ $$uhttp://dx.doi.org/10.1103/PhysRevD.83.114512 000018056 8564_ $$uhttps://juser.fz-juelich.de/record/18056/files/PhysRevD.83.114512.pdf$$yOpenAccess 000018056 8564_ $$uhttps://juser.fz-juelich.de/record/18056/files/PhysRevD.83.114512.gif?subformat=icon$$xicon$$yOpenAccess 000018056 8564_ $$uhttps://juser.fz-juelich.de/record/18056/files/PhysRevD.83.114512.jpg?subformat=icon-180$$xicon-180$$yOpenAccess 000018056 8564_ $$uhttps://juser.fz-juelich.de/record/18056/files/PhysRevD.83.114512.jpg?subformat=icon-700$$xicon-700$$yOpenAccess 000018056 8564_ $$uhttps://juser.fz-juelich.de/record/18056/files/PhysRevD.83.114512.pdf?subformat=pdfa$$xpdfa$$yOpenAccess 000018056 909CO $$ooai:juser.fz-juelich.de:18056$$pdnbdelivery$$pVDB$$pdriver$$popen_access$$popenaire 000018056 9141_ $$y2011 000018056 915__ $$0LIC:(DE-HGF)APS-112012$$2HGFVOC$$aAmerican Physical Society Transfer of Copyright Agreement 000018056 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000018056 915__ $$0StatID:(DE-HGF)0010$$aJCR/ISI refereed 000018056 9132_ $$0G:(DE-HGF)POF3-511$$1G:(DE-HGF)POF3-510$$2G:(DE-HGF)POF3-500$$aDE-HGF$$bKey Technologies$$lSupercomputing & Big Data$$vComputational Science and Mathematical Methods$$x0 000018056 9131_ $$0G:(DE-HGF)POF2-411$$1G:(DE-HGF)POF2-410$$2G:(DE-HGF)POF2-400$$3G:(DE-HGF)POF2$$4G:(DE-HGF)POF$$aDE-HGF$$bSchlüsseltechnologien$$lSupercomputing$$vComputational Science and Mathematical Methods$$x2 000018056 9201_ $$0I:(DE-Juel1)JSC-20090406$$gJSC$$kJSC$$lJülich Supercomputing Centre$$x0 000018056 970__ $$aVDB:(DE-Juel1)132676 000018056 980__ $$aVDB 000018056 980__ $$aConvertedRecord 000018056 980__ $$ajournal 000018056 980__ $$aI:(DE-Juel1)JSC-20090406 000018056 980__ $$aUNRESTRICTED 000018056 9801_ $$aFullTexts
