Semiconductor demonstrates elusive quantum physics model

With a little twist and the turn of a voltage knob, Cornell researchers have shown that a single material system can toggle between two of the wildest states in condensed matter physics: The quantum anomalous Hall insulator ...

Stop-motion photons: Localized light particles on the road

Professor Alexander Szameit and his group of physicists from the University of Rostock, in collaboration with Professor Stefano Longhi from the Polytechnic University of Milan, discovered a novel and paradoxical behavior ...

Magnetism drives metals to insulators in new experiment

Like all metals, silver, copper, and gold are conductors. Electrons flow across them, carrying heat and electricity. While gold is a good conductor under any conditions, some materials have the property of behaving like metal ...

Researchers discover new organic conductor

Salts are far more complicated than the food seasoning—they can even act as electrical conductors, shuttling current through systems. Extremely well studied and understood, the electrical properties of salts were first ...

The future of electronics is stretchy

Stretchable electronic circuits are critical for soft robotics, wearable technologies, and biomedical applications. The current ways of making them, though, have limited their potential.

Electrons hop to it on twisted molecular wires

Researchers at Osaka University synthesized twisted molecular wires just one molecule thick that can conduct electricity with less resistance compared with previous devices. This work may lead to carbon-based electronic devices ...

Conducting

Conducting is the art of directing a musical performance by way of visible gestures. The primary duties of the conductor are to unify performers, set the tempo, execute clear preparations and beats, and to listen critically and shape the sound of the ensemble. Orchestras, choirs, concert bands and other musical ensembles often have conductors.
