Abstract:	Topological quantum matter exhibits transport phenomena driven by entanglement between internal degrees of freedom, as, for instance, generated by spin-orbit coupling effects. Here we report on a direct connection between the mechanism driving spin relaxation and the intertwined dynamics between spin and sublattice degrees of freedom in disordered graphene. Beyond having a direct observable consequence, such intraparticle entanglement is shown to be resilient to disorder, pointing towards a unique resource for quantum information processing.
