A facility for the analysis of the electronic structures of solids and their surfaces by synchrotron radiation photoelectron spectroscopy
M. Hoesch, T. K. Kim, P. Dudin +15
A synchrotron radiation beamline in the photon energy range of 18 - 240 eV and an electron spectroscopy end station have been constructed at the 3 GeV Diamond Light Source storage…
Large Force Fluctuations in a Flowing Granular Medium
Emily Longhi, Nalini Easwar, Narayanan Menon
We report the characteristics of the temporal fluctuations in the local force delivered to the wall of a 2D hopper by a granular medium flowing through it. The forces are predomina…
Memory in 2D heap experiments
Junfei Geng, Emily Longhi, R. P. Behringer +1
The measurement of force distributions in sandpiles provides a useful way to test concepts and models of the way forces propagate within noncohesive granular materials. Recent theo…
Footprints in Sand: The Response of a Granular Material to Local Perturbations
Junfei Geng, D. Howell, E. Longhi +5
We experimentally determine ensemble-averaged responses of granular packings to point forces, and we compare these results to recent models for force propagation in a granular mate…
