Topological Insulators Excited with Lasers Could Have Massless Electrons

At the University of Tsukuba, researchers have shown that electrons can move as if they did not have any mass when some materials known as “topological insulators” are irradiated using laser beams.

New Solution to Solve Measurement Uncertainties Could Have Implications for Quantum Technologies

Shoe shops sell a variety of shoe sizes to accommodate a variety of foot sizes -- but what if both the shoe and foot size depended on how it was measured- Recent developments in quantum theory suggest that the available values of a physical quantity, such as a foot size, can depend on the type of measurement used to determine them.

University of Leicester Physicists Discover a Novel State of Matter

In recent years, active, self-propelled particles have received growing interest amongst the scientific community. Examples of active particles and their systems are numerous and very diverse, ranging from bacterium films to flocks of birds or human crowds. These systems can demonstrate unusual behavior, which is challenging to understand or model.

New Technology Could Boost Quantum Computing and Superconducting Electronics

Superconductors -- materials that conduct electricity without resistance -- are remarkable. They provide a macroscopic glimpse into quantum phenomena, which are usually observable only at the atomic level. Beyond their physical peculiarity, superconductors are also useful. They're found in medical imaging, quantum computers, and cameras used with telescopes.
