Skyrmions are localized, particle-like excitations in materials that retain their structure due to topological constraints (i.e., restrictions arising from properties that remain unchanged under smooth deformations). These ...
A photonics research group co-led by Gregor Weihs of the University of Innsbruck has developed a new technique for generating multi-photon states from quantum dots that overcomes the limitations of conventional approaches. ...
Infrared imaging helps us see things the human eye cannot. The technology—which can make visible body heat, gas leaks or water content, even through smoke or darkness—is used in military surveillance, search and rescue ...
Quantum confinement is a physical effect that occurs when the size of a material—usually a semiconductor or conductor—is reduced to the nanoscale, thereby restricting the movement of electrons or holes.
Lasers that are fabricated directly onto silicon photonic chips offer several advantages over external laser sources, such as greater scalability. Furthermore, photonic chips with these "monolithically" integrated lasers ...
A study conducted by researchers at the University of São Paulo (USP) in Brazil and the Università degli Studi di Roma "La Sapienza" in Italy has synthesized fullerenes and hollow spherical graphene particles using only ...
A Rutgers-led team of scientists has developed an eco-friendly, very stable, ultra-bright material and used it to generate deep-blue light (emission at ~450 nm) in a light-emitting diode (LED), an energy-efficient device ...
Researchers at the Hong Kong University of Science and Technology (HKUST) School of Engineering have cracked a major challenge in display technology by inventing the world's brightest and most energy efficient quantum rod ...
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 ...
Quantum computers have the potential to revolutionize computing by solving complex problems that stump even today's fastest machines. Scientists are exploring whether quantum computers could one day help streamline global ...
