The return of the spin echo

A research team from Garching and Vienna discovered a remarkable echo effect that offers exciting new possibilities for working with quantum information.

Magnetisation controlled at picosecond intervals

A terahertz laser developed at the Paul Scherrer Institute makes it possible to control a material's magnetisation at a timescale of picoseconds. In their experiment, the researchers shone extremely short light pulses from ...

Dolphins inspire rescue radar device

British engineers said Wednesday they had taken inspiration from dolphins for a new type of radar device that could easily track miners trapped underground or skiers buried in an avalanche.

Directivity to improve optical devices

A team of researchers from the Dutch institute AMOLF, Western University (Canada), and the University of Texas (United States of America) recently demonstrated the use of algorithmic design to create a new type of nanophotonic ...

A new window into the world of attosecond phenomena

They are everywhere, around us and within us. Phenomena lasting trillionths of a second form the core of chemistry and biology. It is only recently that we have begun to try to accurately record their actual course, with ...

Lasers tailor graphene for new electronics technology

Carbon nanomaterials display extraordinary physical properties, outstanding among any other substance available, and graphene has grown as the most promising material for brand-new electronic circuitry, sensors and optical ...

An electrical switch for magnetic current

(PhysOrg.com) -- A new mechanism will make it possible to switch data storage in the future. Researchers at the Max Planck Institute of Microstructure Physics in Halle use a short electric pulse to change the magnetic transport ...
