Description
Over the past decade, a wealth of new data has ushered in an era of precision cosmic-ray physics. By revealing previously unanticipated features in cosmic-ray spectra, these observations challenge current paradigms of Galactic cosmic-ray acceleration and transport. When it comes to modeling cosmic-ray transport in magnetic turbulence, existing theoretical models still struggle to accurately reproduce simulation results, even in highly simplified turbulent magnetic-field configurations. In this talk, I will present our ongoing efforts to investigate the fundamental properties of magnetic field lines and cosmic-ray transport in synthetic turbulence, and show how these results can help us interpret transport in MHD turbulence. I will highlight remarkable similarities between the two cases and discuss their differences.
