From integrated photonics to quantum information science, the ability to control light with electric fields—a phenomenon known as the electro-optic effect—supports vital applications such as light modulation and frequency transduction. These components rely on nonlinear optical materials, in which light waves can be manipulated by applying electric fields. Go to Source Researchers at the Technical University of Munich (TUM) have invented an entirely new field of microscopy called nuclear spin microscopy. The team can visualize magnetic signals of nuclear magnetic resonance with a microscope. Quantum sensors convert the signals into light, enabling extremely high-resolution optical imaging. Go to Source Dark matter is an elusive type of matter that does not emit, absorb or reflect light and is thus impossible to detect using conventional techniques employed in particle physics. In recent years, groups of physicists worldwide have been trying to observe this matter indirectly using advanced detectors and equipment, by detecting signals other than electromagnetic […] A team led by researchers at UNC-Chapel Hill have made an extraordinary discovery that is reshaping our understanding of bubbles and their movement. Picture tiny air bubbles inside a container filled with liquid. When the container is shaken up and down, these bubbles engage in an unexpected, rhythmic “galloping” motion—bouncing like playful horses and moving […] What do rope winding and giant pasta shapes have to do with particle physics? The answer is a new superconducting magnet prototype under development at CERN, lovingly named Fusillo because of its shape. Go to Source You may recognize graphite as the “lead” in a pencil, but besides helping you take notes or fill in countless bubbles on exam answer sheets, it is helping scientists grapple with the secrets of superconductivity. Go to Source Quantum light sources are fickle. They can flicker like stars in the night sky and can fade out like a dying flashlight. However, newly published research from the University of Oklahoma proves that adding a covering to one of these light sources, called a colloidal quantum dot, can cause them to shine without faltering, opening […] Researchers developed a theoretical model that predicts a substantial increase in the brightness of organic light-emitting diodes (OLEDs) by leveraging novel quantum states called polaritons. Integrating polaritons into OLEDs effectively requires the discovery of new materials, making practical implementation an exciting challenge. Go to Source Experiments coupling light and sound reveal the surprising effect that measuring nothing can cool the vibrations of an object. Go to Source An international research collaboration led by the University of Surrey’s Nuclear Physics Group has overturned the long-standing belief that the atomic nucleus of lead-208 (²⁰⁸Pb) is perfectly spherical. The discovery challenges fundamental assumptions about nuclear structure and has far-reaching implications for our understanding of how the heaviest elements are formed in the universe. Go to […] An early-career physicist mathematically connects timelike and spacelike form factors, opening the door to further insights into the inner workings of the strong force. A new lattice QCD calculation connects two seemingly disparate reactions involving the pion, the lightest particle governed by the strong interaction. Go to Source A new Nature Physics study has shed light on the long-hypothesized liquid-liquid critical point where water simultaneously exists in two distinct liquid forms, opening new possibilities for experimental validation. Go to Source Photonics researchers from Tampere University, Finland, and Kastler-Brossel Laboratory, France, have demonstrated how self-imaging of light, a phenomenon known for nearly two centuries, can be applied to cylindrical systems, facilitating unprecedented control of light’s structure with great potential for advanced optical communication systems. In addition, a new type of space-time duality was explored for powerful […] ETH Zurich researchers have investigated how tiny gas bubbles can deliver drugs into cells in a targeted manner using ultrasound. For the first time, they have visualized how tiny cyclic microjets liquid jets generated by microbubbles penetrate the cell membrane, enabling the drug uptake. Go to Source Researchers at the University of Bayreuth have developed a method that makes objects on a magnetic field invisible within a particle stream. Until now, this so-called cloaking had only been studied for waves such as light or sound. They report their results in Nature Communications. Go to Source |
