When atoms are surfing on optical waves

Researchers are working on next generation's computer: They made cold atoms interact with miniature gold wires as small as a thousandth of a millimeter. Illuminating the wires with laser light in a special way, the physicists concentrated the light field at the surface of the wires and, by that, generated so-called surface plasmons.

Flowing structures in soft crystals

A liquid does not have to be a disordered bunch of particles: A team of researchers at Vienna University of Technology (TU Vienna) and the University of Vienna has discovered intriguing structures formed by tiny particles floating in liquids. Under mechanical strain, particle clusters in liquids can spontaneously form strings and dramatically alter the properties of the liquid.

Wo Elektronen im Stau stehen

Der duennste Draht der Welt, hergestellt aus purem Gold, wird von Physikern der Universitaeten Wuerzburg und Kassel untersucht. Fuer Aufsehen sorgt jetzt seine ungewoehnliche elektrische Leitfaehigkeit: Die Elektronen bewegen sich nicht frei durch den Draht, sondern wie Autos im Stop-and-Go-Verkehr.
