This is the second of a three-part study of the ac response of liquid helium. We derive the temperature response function, ΔT(ω), of a3He-superfluid4He mixture from the equations of superfluid hydrodynamics in the presence of two interfacial bounda

Experiments on sheared granular materials show that the stresses grow as the first power of the log of the shear rate, γ. We suggest that this may be evidence of the stress ensemble recently proposed by Henkes, O’Hern, and Chakraborty. The picture

A complete understanding of the microscopic dynamics of a monolayer of identical spheres moving on a substrate must encompass the effects of collisions and the substrate on the particles. We begin from first principles by considering collections of s

We probe the nature of slow flow in the shear band of a 2D granular Couette experiment. The experiment consists of an inner shearing wheel, an outer circular boundary, and particles which occupy the space between these two. The mean flow is strictly

In order to probe the process of energy propagation through dense granular systems, we carry out discrete element simulations of the system response to excitations where we control the driving frequency and wavelength independently. The soft‐disk s

This work focuses on the evolution of fabric and stress tensors for an assembly of dense 2D photoelastic particles subjected to cyclic pure shear. The fabric and stress tensors are computed from the contact network and contact forces using particle t

We consider jamming that occurs for the flow of dry granular materials from a hopper as the outlet size, D, is reduced relative to the particle size, d. We propose and test a model based on the simple idea that the probability of jamming on a short t
