We performed molecular dynamics simulations of a binary Lennard-Jones mixture at different temperatures and investigated the spatiotemporal autocorrelation function of the shear stress for different wavevectors, q, from a locally measured and Fourier-transformed stress tensor. Anisotropic correlations are observed at non-zero wavevectors, exhibiting strongly damped oscillations with a characteristic frequency ω( q). A comparison with a recently developed hydrodynamic theory [Maier et al., Phys. Rev. Lett. 119, 265701 (2017)] shows a remarkably good quantitative agreement between particle-based simulations and theoretical predictions."],["dc.description.sponsorship"," Alexander von Humboldt-Stiftung http://dx.doi.org/10.13039/100005156"],["dc.identifier.doi","10.1063/5.0098265"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/113685"],["dc.language.iso","en"],["dc.notes.intern","DOI-Import GROB-597"],["dc.relation.eissn","1089-7690"],["dc.relation.issn","0021-9606"],["dc.title","Molecular simulations and hydrodynamic theory of nonlocal shear-stress correlations in supercooled fluids"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dspace.entity.type","Publication"]]
