Exceptional points (EPs) are non-Hermitian singularities where two or more eigenstates coalesce, resulting in the eigenspace collapsing in dimensionality. Over the past decade, researchers have uncovered a wealth of exotic phenomena near EPs. Go to Source Scientists have developed a new platform for the generation and detection of ultrashort UV-C laser pulses on femtosecond timescales. This breakthrough could unlock new opportunities for transforming optical wireless communication systems, material processing applications and medical imaging. Go to Source In spaces smaller than a wavelength of light, electric currents jump from point to point and magnetic fields corkscrew through atomic lattices in ways that defy intuition. Scientists have only ever dreamed of observing these marvels directly. Go to Source Researchers from the University of Oxford have for the first time discovered an approach to electrically switch organic LEDs (OLEDs) to emit either left- or right-handed circularly polarized light without changing the light-emitting molecules. This could be useful for a range of technological applications, from more energy efficient OLED displays, to optical information transfer. Go […] University of Houston researchers developed a new X-ray imaging method capable of revealing hidden features in a single shot, a breakthrough that could advance cancer detection, disease monitoring, security screening and material analysis. Go to Source Machine learning models called convolutional neural networks (CNNs) power technologies like image recognition and language translation. A quantum counterpart—known as a quantum convolutional neural network (QCNN)—could process information more efficiently by using quantum states instead of classical bits. Go to Source The quantum world is famously weird—a single particle can be in two places at once, its properties are undefined until they are measured, and the very act of measuring a quantum system changes everything. But according to new research published in Physical Review Letters, the quantum world is even stranger than previously thought. Go to […] As part of the QuNET project, researchers have demonstrated how quantum key distribution works reliably via hybrid and mobile channels. The results are milestones for sovereign, quantum-secured communication in Germany and have been published in the New Journal of Physics. Go to Source Superconductive materials can conduct electricity with no resistance, but typically only at very low temperatures. Realizing superconductivity at room temperature could enable advanced, energy-efficient electronics and other technologies. Go to Source Researchers at the University of Basel have developed a new approach to applying thermodynamics to microscopic quantum systems. Go to Source Consciousness is fundamental; only thereafter do time, space and matter arise. This is the starting point for a new theoretical model of the nature of reality, presented by Maria Strømme, Professor of Materials Science at Uppsala University, in AIP Advances. The article has been selected as the best paper of the issue and featured on […] Energy that would normally go to waste inside powerful particle accelerators could be used to create valuable medical isotopes, scientists have found. Go to Source A novel magnetic material with an extraordinary electronic structure might allow for the production of smaller and more efficient computer chips in the future: the p-wave magnet. Researchers from Karlsruhe Institute of Technology (KIT) were involved in its development. Go to Source While atmospheric turbulence is a familiar culprit of rough flights, the chaotic movement of turbulent flows remains an unsolved problem in physics. To gain insight into the system, a team of researchers used explainable AI to pinpoint the most important regions in a turbulent flow, according to a Nature Communications study led by the University […] Quantum computers, which operate leveraging effects rooted in quantum mechanics, have the potential of tackling some computational and optimization tasks that cannot be solved by classical computers. Instead of bits (i.e., binary digits), which are the basic units of information in classical computers, quantum computers rely on so-called qubits. Go to Source […] |
