Direct experimental evidence of free-fermion antibunching.
Fermion antibunching was observed on a beam of free noninteracting neutrons. A monochromatic beam of thermal neutrons was first split by a graphite single crystal, then fed to two detectors, displaying a reduced coincidence rate. The result is a fermionic complement to the Hanbury Brown and Twiss effect for photons.
متن کاملCrossover from intermittent to continuum dynamics for locally driven colloids.
We simulate a colloid with charge q(d) driven through a disordered assembly of interacting colloids with charge q and show that, for q(d) approximately q, the velocity-force relation is nonlinear and the velocity fluctuations of the driven particle are highly intermittent with a 1/f characteristic. When g(d) >>q , the average velocity drops, the velocity-force relation becomes linear, and the v...

A benign enchondroma of the left fifth distal interphalangeal joint occurred in a 39 year old male. The differential diagnoses and outcomes are discussed.
متن کاملExperimental measurement of an effective temperature for jammed granular materials.
A densely packed granular system is an example of an out-of-equilibrium system in the jammed state. It has been a longstanding problem to determine whether this class of systems can be described by concepts arising from equilibrium statistical mechanics, such as an effective temperature and compactivity. The measurement of the effective temperature is realized in the laboratory by slowly sheari...
متن کاملJammed elastic shells - a 3D experimental soft frictionless granular system.
We present a new experimental system of monodisperse, soft, frictionless, fluorescent labeled elastic shells for the characterization of structure, universal scaling laws and force networks in 3D jammed matter. The elastic shells in a jammed packing are deformed in such a way that at each contact one of the shells buckles with a dimple and the other remain spherical, closely resembling overlapp...
