Topological quantum materials, where spin-momentum locking is believed to lead to particularly long spin lifetimes, are regarded as a promising platform for such applications. However, spin-orbit coupling, that is essential to all topological matter, at the same time gives rise to spin mixing and decoherence as a major obstacle for quantum computing. Here, we give experimental evidence that hot-spots of spin-mixing and spin-conserving contributions of the spin-orbit operator coexist in an archetypal topological Dirac metal, and that these hot spots can have a strongly anisotropic distribution of their respective wave vectors with respect to the spin quantization direction. Our results can be understood within a theory that takes into account the decomposition of the spin-orbit Hamiltonian into spin-conserving and spin-flip terms, contributing to a better understanding of quantum decoherence in topological materials, in general 000894490 536__ $$0G:(DE-HGF)POF4-5211$$a5211 - Topological Matter (POF4-521)$$cPOF4-521$$fPOF IV$$x0 000894490 588__ $$aDataset connected to CrossRef, Journals: juser.fz-juelich.de 000894490 7001_ $$0P:(DE-Juel1)162311$$aHoffmann, Markus$$b1 000894490 7001_ $$0P:(DE-Juel1)131065$$aZimmermann, Bernd$$b2 000894490 7001_ $$0P:(DE-Juel1)130545$$aBihlmayer, Gustav$$b3 000894490 7001_ $$0P:(DE-Juel1)130548$$aBlügel, Stefan$$b4 000894490 7001_ $$0P:(DE-Juel1)130948$$aSchneider, Claus M.$$b5 000894490 7001_ $$0P:(DE-Juel1)168293$$aTusche, Christian$$b6$$eCorresponding author$$ufzj 000894490 773__ $$0PERI:(DE-600)2921913-9$$a10.1038/s42005-021-00682-5$$gVol. 4, no. 1, p. 179$$n1$$p179$$tCommunications Physics$$v4$$x2399-3650$$y2021 000894490 8564_ $$uhttps://juser.fz-juelich.de/record/894490/files/s42005-021-00682-5.pdf$$yOpenAccess 000894490 8767_ $$8SN-2021-00708-b$$92021-12-02$$d2021-12-07$$eAPC$$jDEAL$$lDEAL: Springer$$zBelegnr.: 1200174041 000894490 909CO $$ooai:juser.fz-juelich.de:894490$$pVDB$$pdriver$$pOpenAPC$$popen_access$$popenaire$$popenCost$$pdnbdelivery 000894490 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)171668$$aForschungszentrum Jülich$$b0$$kFZJ 000894490 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)162311$$aForschungszentrum Jülich$$b1$$kFZJ 000894490 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)130545$$aForschungszentrum Jülich$$b3$$kFZJ 000894490 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)130548$$aForschungszentrum Jülich$$b4$$kFZJ 000894490 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)130948$$aForschungszentrum Jülich$$b5$$kFZJ 000894490 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)168293$$aForschungszentrum Jülich$$b6$$kFZJ 000894490 9131_ $$0G:(DE-HGF)POF4-521$$1G:(DE-HGF)POF4-520$$2G:(DE-HGF)POF4-500$$3G:(DE-HGF)POF4$$4G:(DE-HGF)POF$$9G:(DE-HGF)POF4-5211$$aDE-HGF$$bKey Technologies$$lNatural, Artificial and Cognitive Information Processing$$vQuantum Materials$$x0 000894490 9141_ $$y2021 000894490 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS$$d2021-02-04 000894490 915__ $$0StatID:(DE-HGF)0160$$2StatID$$aDBCoverage$$bEssential Science Indicators$$d2021-02-04 000894490 915__ $$0LIC:(DE-HGF)CCBY4$$2HGFVOC$$aCreative Commons Attribution CC BY 4.0 000894490 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR$$bCOMMUN PHYS-UK : 2019$$d2021-02-04 000894490 915__ $$0StatID:(DE-HGF)0501$$2StatID$$aDBCoverage$$bDOAJ Seal$$d2021-02-04 000894490 915__ $$0StatID:(DE-HGF)0500$$2StatID$$aDBCoverage$$bDOAJ$$d2021-02-04 000894490 915__ $$0StatID:(DE-HGF)0113$$2StatID$$aWoS$$bScience Citation Index Expanded$$d2021-02-04 000894490 915__ $$0StatID:(DE-HGF)0700$$2StatID$$aFees$$d2021-02-04 000894490 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection$$d2021-02-04 000894490 915__ $$0StatID:(DE-HGF)9900$$2StatID$$aIF < 5$$d2021-02-04 000894490 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000894490 915__ $$0StatID:(DE-HGF)0030$$2StatID$$aPeer Review$$bDOAJ : Blind peer review$$d2021-02-04 000894490 915__ $$0StatID:(DE-HGF)0561$$2StatID$$aArticle Processing Charges$$d2021-02-04 000894490 915__ $$0StatID:(DE-HGF)1150$$2StatID$$aDBCoverage$$bCurrent Contents - Physical, Chemical and Earth Sciences$$d2021-02-04 000894490 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline$$d2021-02-04 000894490 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bClarivate Analytics Master Journal List$$d2021-02-04 000894490 9201_ $$0I:(DE-Juel1)IAS-1-20090406$$kIAS-1$$lQuanten-Theorie der Materialien$$x0 000894490 9201_ $$0I:(DE-Juel1)PGI-1-20110106$$kPGI-1$$lQuanten-Theorie der Materialien$$x1 000894490 9201_ $$0I:(DE-82)080009_20140620$$kJARA-FIT$$lJARA-FIT$$x2 000894490 9201_ $$0I:(DE-82)080012_20140620$$kJARA-HPC$$lJARA - HPC$$x3 000894490 9201_ $$0I:(DE-Juel1)PGI-6-20110106$$kPGI-6$$lElektronische Eigenschaften$$x4 000894490 9801_ $$aFullTexts 000894490 980__ $$ajournal 000894490 980__ $$aVDB 000894490 980__ $$aUNRESTRICTED 000894490 980__ $$aI:(DE-Juel1)IAS-1-20090406 000894490 980__ $$aI:(DE-Juel1)PGI-1-20110106 000894490 980__ $$aI:(DE-82)080009_20140620 000894490 980__ $$aI:(DE-82)080012_20140620 000894490 980__ $$aI:(DE-Juel1)PGI-6-20110106 000894490 980__ $$aAPC
