The exponent depends on the confining geometry, rather than the spatial dimensionality. We can account for the tail by using a simple mode-coupling theory which exploits the fact that the sound wave generated by a moving particle becomes diffusive.5 p.application/pdfeng(c) American Physical Society, 1997Química físicaReologiaSimulació per ordinadorPhysical and theoretical chemistryRheologyComputer simulationinfo:eu-repo/semantics/article507882info:eu-repo/semantics/openAccess
