Researchers realize non-Hermitian exceptional points in degenerate optical cavity

Recently, a research team led by Prof. Guo Guangcan from the University of Science and Technology of China (USTC) constructed a non-Hermiticity (NH) synthetic orbital angular momentum (OAM) dimension in a degenerate optical ...

Discovering the magic in superconductivity's 'magic angle'

Researchers have produced new evidence of how graphene, when twisted to a precise angle, can become a superconductor, moving electricity with no loss of energy.

Mid-twentieth-century physics in the home of Galileo

Florence was a flourishing center for fundamental physics research throughout most of the twentieth century. Roberto Casalbuoni, Daniele Dominici and Massimo Mazzoni—all physicists currently working there—have reviewed ...

Scientists observe 'quasiparticles' in classical systems for the first time

Starting with the emergence of quantum mechanics, the world of physics has been divided between classical and quantum physics. Classical physics deals with the motions of objects we typically see every day in the macroscopic ...

Twisting up atoms through space and time

One of the most exciting applications of quantum computers will be to direct their gaze inwards, at the very quantum rules that make them tick. Quantum computers can be used to simulate quantum physics itself, and perhaps ...

Researcher posits that electrons do spin, thanks to their fields

Deep inside all matter in the universe, electrons are buzzing around and behaving as if they are twirling around on their axes like spinning tops. These "spinning" electrons are fundamental to quantum physics and play a central ...

The seven-year photobomb: Distant star's dimming was likely a 'dusty' companion getting in the way, astronomers say

By their own admission, Anastasios "Andy" Tzanidakis and James Davenport are interested in unusual stars. The University of Washington astronomers were on the lookout for "stars behaving strangely" when an automated alert ...

Researchers show a new way to induce useful defects using invisible material properties

Much of modern electronic and computing technology is based on one idea: Add chemical impurities, or defects, to semiconductors to change their ability to conduct electricity. These altered materials are then combined in ...
