Time-state superposition in non-equilibrium fluidized granular matter
Marlo Kunzner, W. Till Kranz, Matthias Sperl +1
Despite being intrinsically athermal and strongly driven, granular materials can exhibit remarkably glass-like dynamics. Whether their rheology can be described by the same scaling…

Granular rheology: a tale of three time scales
Olivier Coquand, Wolf Till Kranz, Matthias Sperl
We adapt statistical models of the physics of complex fluids to study the rheology of granular liquids. This allows us to provide laws of granular rheology based on first principle…

Rheological regimes in agitated granular media under shear
Olfa D'Angelo, Matthias Sperl, W. Till Kranz
Agitated granular media have a rich rheology: they exhibit Newtonian behavior at low shear rate and density, develop a yield stress at high density, and cross over to Bagnoldian sh…
