DOI: 10.1103/physreve.105.024901
Abstract: The frictional instability associated with earthquake initiation and earthquake dynamics is believed to be mainly controlled by the dynamics of fragmented rocks within the fault gauge. Principal features of the emerging seismicity (e.g., intermittent dynamics… read more here.

Abstract: A two-dimensional granular packing under horizontally circular shaking exhibits various collective motion modes where nonuniform density distribution and correlated dynamics are present. For intermediate packing density and oscillation amplitude, a condensed phase travels around the… read more here.

DOI: 10.1126/sciadv.adf6243
Abstract: From Mars rovers to buildings, objects eventually sink and tilt into a fluidized granular bed due to gravity. Despite the irregular shape of realistic granular intruders, most research focus on the settling of “perfect” objects… read more here.
