Singular electrostatic energy of nanoparticle clusters
Jian Qin, Nathan W. Krapf, Thomas A. Witten
The binding of clusters of metal nanoparticles is partly electrostatic. We address difficulties in calculating the electrostatic energy when high charging energies limit the total…
Force propagation in isostatic granular packs
Nathan Krapf
We investigate how forces spread through frictionless granular packs at the jamming transition. Previous work has indicated that such packs are isostatic, and thus obey a null stre…

Chiral sedimentation of extended objects in viscous media
Nathan W. Krapf, Thomas A. Witten, Nathan C. Keim
We study theoretically the chirality of a generic rigid object's sedimentation in a fluid under gravity in the low Reynolds number regime. We represent the object as a collection o…
