Query: Packings of frictionless spherocylinders   We present simulation results on the properties of packings of frictionless
spherocylindrical particles. Starting from a random distribution of particles
in space, a packing is produced by minimizing the potential energy of
inter-particle contacts until a force-equilibrated state is reached. For
different particle aspect ratios $\alpha=10\ldots 40$, we calculate contacts
$z$, pressure as well as bulk and shear modulus. Most important is the fraction
$f_0$ of spherocylinders with contacts at both ends as it governs the jamming
threshold $z_c(f_0)=8+2f_0$. These results highlight the important role of the
axial "sliding" degree of freedom of a spherocylinder, which is a zero-energy
mode but only if no end-contacts are present.
