Quantenlego: Materie aus einzelnen Atomen gebastelt

Die Bewegungen mehrerer, miteinander wechselwirkender Körper zu verstehen, gehört zu den zentralen Forschungsfragen in der Physik. Während zunächst das Verständnis der Bahnen von Himmelskörpern im Vordergrund stand, hat diese Fragestellung in quantenmechanischen Vielteilchensystemen, beispielsweise bei der Beschreibung von Elektronen in einem Festkörper,...

Nanosheets line up to mimic nature

A soft material that mimics natural cartilage in that it is easily deformed by shear forces in one direction yet resists compressive forces applied in other directions has been developed by a team led by scientists from the RIKEN Center for Emergent Matter Science ("An anisotropic hydrogel with electrostatic repulsion between cofacially aligned nanosheets")....

Skyrmions get a sonic touch

Skyrmions are stable nanoscale magnetic whirls that are emerging as promising candidates for memory and data storage devices, although difficulties in finding practical ways of controlling them have hampered progress. RIKEN researchers have now discovered that sound waves can be used to both measure the elasticity of skyrmions and drive their oscillation...
