For the first time ever, researchers prove that atomic vibrations can transfer orbital angular momentum directly to electrons in a non-magnetic material with chiral symmatry, the most streamlined system yet in the exciting new field of ‘orbitronics’

DTU researchers have invented a nanolaser constructed in a semiconductor membrane that causes electrons and light to gather in a small area (blue shadow). By using light instead of electrical signals on microchips, data speed can be increased and energy loss reduced. Illustration: Yi Yu. The invention of a nanolaser is the first step towards future digital communication, where communication on microchips can be based entirely on light particles. Researchers at DTU have develo

The researchers used a laser pulse (blue) to change the polarity of a ferromagnetic state in a special material consisting of twisted atomic layers (red).   (Visualisation: Enrique Sahagún, Scixel / ETH Zurich, University of Basel) Researchers at ETH Zurich and the University of Basel have succeeded in changing the polarity of a special ferromagnet using a laser beam. In the future, this method could be used to create adaptable electronic circuits with light.     In a ferroma

In a new study, an international group of researchers has found that chiral phonons can create orbital current without needing magnetic elements – in part because chiral phonons have their own magnetic moments. Additionally, this effect can be achieved in common crystal materials. The work has potential for the development of less expensive, energy-efficient orbitronic devices for use in a wide array of electronics. All electronic devices are based upon the charge of an elect

Researchers at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) have uncovered previously unobserved oscillation states – so-called Floquet states – in tiny magnetic vortices. Unlike earlier experiments, which required energy-intensive laser pulses to create such states, the team in Dresden discovered that a subtle excitation with magnetic waves is sufficient. This finding not only raises fundamental questions in basic physics but could also eventually serve as a universal ada

A research team led by Professor Leo Tianshuo Zhao from the Department of Electrical and Electronic Engineering at the Faculty of Engineering, University of Hong Kong (HKU), has developed the world’s smallest fully printed infrared photodetectors, which are an innovative room-temperature nano-printing platform that overcomes the limitations of traditional silicon-based technology. Near-infrared (NIR) technology is essential for applications such as autonomous systems, biomedi
