Supersonic waves may help electronics beat the heat

Researchers at the Department of Energy's Oak Ridge National Laboratory made the first observations of waves of atomic rearrangements, known as phasons, propagating supersonically through a vibrating crystal latticeā€”a discovery ...

Wiggling atoms switch the electric polarization of crystals

Ferroelectric crystals display a macroscopic electric polarization, a superposition of many dipoles at the atomic scale that originate from spatially separated electrons and atomic nuclei. The macroscopic polarization is ...

Attoseconds break into atomic interior

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons ...

Mystery of the dark solitons

When your heart beats, blood courses through your arteries in waves of pressure. These pressure waves manifest as your pulse, a regular rhythm unperturbed by the complex internal structure of the body. Scientists call such ...
