Scientists find ordered magnetic patterns in disordered magnetic material

A team of scientists working at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) has confirmed a special property known as "chirality—which potentially could be exploited to transmit and store ...

Maxwell's demon in the quantum Zeno regime

In the original Maxwell's demon thought experiment, a demon makes continuous measurements on a system of hot and cold reservoirs, building up a thermal gradient that can later be used to perform work. As the demon's measurements ...

Quan­tum physics turned into tan­gi­ble re­al­ity

ETH physicists have developed a silicon wafer that behaves like a topological insulator when stimulated using ultrasound. They have thereby succeeded in turning an abstract theoretical concept into a macroscopic product.

Pure optical detection of spikes for the ultimate brain machine interface

(Âé¶¹ÒùÔº)—Brain-machine interfaces (BMIs) are basically gimmicks. The reason you don't hear so much about them these days is because, in the fullness of time, significant tangible benefit to a user has flat out failed ...

Two ways to improve optical sensing using different resonator techniques

(Âé¶¹ÒùÔº)—Two independent teams working on research aimed at improving optical sensing have used techniques that involve coupling two or more modes of light such that their modes and their corresponding frequencies coalesce, ...

Helically twisted photonic crystal fibres

Photonic crystal fibres (PCF) are strands of glass, not much thicker than a human hair, with a lattice of hollow channels running along the fibre. If they are continuously twisted in their production, they resemble a multi-helix. ...

First-ever direct observation of chiral currents in quantum Hall atomic simulation

Using an atomic quantum simulator, scientists at the University of Illinois at Urbana-Champaign have achieved the first-ever direct observation of chiral currents in the model topological insulator, the 2-D integer quantum ...

Researchers develop fully textile waveguide antenna using a metamaterial-inspired unit cell

Researchers at Katholieke Universiteit Leuven and Universiti Malaysia Perlis are the first to have developed a fully textile waveguide antenna using a metamaterial inspired unit cell that is also used in composite right/left-handed ...
