For decades, scientists have looked to light as a way to speed up computing. Photonic neural networks—systems that use light instead of electricity to process information—promise faster speeds and lower energy use than ...
Excitons—bound pairs of electrons and an electron hole—are quasiparticles that can arise in solids. While so-called "bright" excitons emit light and are therefore accessible, dark excitons are optically inactive. As a ...
Twisted materials—known as moiré structures—have revolutionized modern physics, emerging as today's "alchemy" by creating entirely new phases of matter through simple geometric manipulation. The term "moiré" may sound ...
Many displays found in smartphones and televisions rely on thin-film transistors (TFTs) made from indium gallium zinc oxide (IGZO) to control pixels. IGZO offers high transparency due to its large bandgap (the gap existing ...
Quantum mechanics has a reputation that precedes it. Virtually everyone who has bumped up against the quantum realm, whether in a physics class, in the lab, or in popular science writing, is left thinking something like, ...
For over two decades, physicists have been working toward implementing quantum light storage—also known as quantum memory—in various matter systems. These techniques allow for the controlled and reversible mapping of ...
Recent physics studies have found that light can sometimes flow in unexpected ways, behaving like a so-called "superfluid." Superfluids, such as ultracold atomic gases or helium-4 below specific temperatures, are phases of ...
Researchers at the University of Colorado Boulder have created a new way to build and control tiny particles that can move and work like microscopic robots, offering a powerful tool with applications in biomedical and environmental ...
Optical quantum clocks developed at the University of Adelaide have been proven to outperform GPS navigation systems by many orders of magnitude. The clocks, which were put through their paces in naval exercises, were designed ...
A set of breakthroughs from scientists at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) is offering a new understanding of how energy flows through one of nature's most important molecular ...
