When an electric current flows through a material in the presence of a magnetic field, its electrons experience a subtle sideways force which deflects their path. This effect of electron deflection is called the Hall effect—a phenomenon that lies at the heart of modern sensors and electronic devices. When this effect results from internal magnetization of the conducting material, it is called “anomalous Hall effect (AHE).” Scientists have long believed that the Hall effect on

Improved electron flow enables electrical conduction in nanoscale components – structures measured in billionths of a metre. In this way, a quantum scar can act as a nanoscale switch, akin to a novel type of transistor. This breakthrough opens the door to developing components for the small and energy-efficient microchips of the future. These findings pave the way for a new field dubbed ‘scartronics,’ where quantum scars guide the conductivity of nanoscale devices. Experiment

For the first time, chemists at ETH Zurich have successfully used extremely short, rotating flashes of light to measure and manipulate the different movements of electrons in mirror-image molecules. They showed that chirality of molecules is not just a structural but also an electronic phenomenon...

Caltech team led by Alireza Marandi, a professor of electrical engineering and applied physics at Caltech, has created a tiny device capable of producing an unusually wide range of laser-light frequencies with ultra-high efficiency—all on a microchip.

With NSF support, WashU physicists create quantum sensors that track stress and magnetism at pressures exceeding 30,000 times Earth’s atmosphere

Graphene is an extraordinary material – a sheet of interlocking carbon atoms just one atom thick that is stable and extremely conductive. This makes it useful in a range of areas, such as flexible electronic displays, highly precise sensors, powerful batteries, and efficient solar cells. A new study – led by the University of Göttingen, working together with colleagues from Braunschweig and Bremen in Germany, and Fribourg in Switzerland – now takes graphene’s potential to a w
