Using an instrument on the 4.1-meter Southern Astrophysical Research Telescope, researchers obtained the first astronomical spectrum using skipper charge-coupled devices (CCDs). The results were presented on June 16 at the Society of Photo-Optical Instrumentation Engineers Astronomical Telescopes + Instrumentation meeting in Japan by Edgar Marrufo Villalpando, a physics PhD candidate at the University of Chicago and a Fermilab DOE Graduate Instrumentation Research Award Fellow. “This is a major milestone for skipper-CCD technology,” said Alex Drlica-Wagner, a cosmologist at the U.S. Department…
Researchers have reported previously unobserved phenomena in an ultra-clean sample of the correlated metal SrVO3. The study challenges existing theoretical models by providing new experimental insights into these unusual metals. The team demonstrated that high-purity SrVO3 exhibits unique electronic properties, revealing the importance of defect-free materials in studying electron correlation effects. The study’s breakthrough was achieved using an innovative thin film growth technique, leading to the synthesis of SrVO3 with unprecedented purity, enabling detailed exploration of its true properties. Findings…
New findungs on light published by scientists from the University of Rostock. A collaboration of Professor Szameit’s research group at the University of Rostock with researchers from the Albert-Ludwigs-Universität Freiburg has succeeded in stabilizing the interference of two photons in optical chips with the concept of topologically protected wave propagation. The research results were published in the renowned journal Science. (from left to right) Matthias Heinrich, Alexander Szameit and Max Ehrhardt – the authors of the Science paper – experimenting…
Researchers develop method to confine light inside an organic material to form a hybrid quantum state, creating new physical and chemical properties. A team of international scientists led by the University of Ottawa have gone back to the kitchen cupboard to create a recipe that combines organic material and light to create quantum states. Professor Jean-Michel Ménard, leader of the Ultrafast Terahertz Spectroscopy group at the Faculty of Science, coordinated with Dr. Claudiu Genes at the Max Planck Institute for…
With speeds over 200 times faster than traditional methods, new technology could benefit autonomous driving, industrial inspection and security applications. Researchers have developed a new 3D method that can be used to track fast-moving objects at unprecedented high speeds. The real-time tracking approach, which is based on single-pixel imaging, could be used to improve autonomous driving, industrial inspection and security surveillance systems. “Our approach does not require reconstructing the object’s image to calculate its position, which significantly reduces data storage…
In late 2019 the previously unremarkable galaxy SDSS1335+0728 suddenly started shining brighter than ever before. To understand why, astronomers have used data from several space and ground-based observatories, including the European Southern Observatory’s Very Large Telescope (ESO’s VLT), to track how the galaxy’s brightness has varied. In a study out today, they conclude that they are witnessing changes never seen before in a galaxy — likely the result of the sudden awakening of the massive black hole at its core….
Mission to find gamma ray bursts is latest to use technology from University of Leicester in X-ray optics. A satellite telescope designed to rapidly hunt down the universe’s biggest explosions will launch later this week, carrying technology developed at the University of Leicester. The Space Variable Objects Monitor (SVOM) is the second mission this year to benefit from expertise in X-ray optics at Leicester, following the launch of Einstein Probe in January. The SVOM mission (Space-based multi-band astronomical Variable Objects…
A team of scientists used NASA’s James Webb Space Telescope to parse the composition of the Crab Nebula, a supernova remnant located 6,500 light-years away in the constellation Taurus. With the telescope’s MIRI (Mid-Infrared Instrument) and NIRCam (Near-Infrared Camera), the team gathered data that is helping to clarify the Crab Nebula’s history. The Crab Nebula is the result of a core-collapse supernova from the death of a massive star. The supernova explosion itself was seen on Earth in 1054 CE and was bright enough to…
Quantum entangled photons react to Earth’s spin. A team of researchers led by Philip Walther at the University of Vienna carried out a pioneering experiment where they measured the effect of the rotation of Earth on quantum entangled photons. The work, just published in Science Advances, represents a significant achievement that pushes the boundaries of rotation sensitivity in entanglement-based sensors, potentially setting the stage for further exploration at the intersection between quantum mechanics and general relativity. Optical Sagnac interferometers are…
Technology eliminates optical-electronic conversions, holds promise for revolutionizing edge intelligence. Researchers have demonstrated a new intelligent photonic sensing-computing chip that can process, transmit and reconstruct images of a scene within nanoseconds. This advance opens the door to extremely high-speed image processing that could benefit edge intelligence for machine vision applications such as autonomous driving, industrial inspection and robotic vision. Edge computing, which performs intensive computing tasks like image processing and analysis on local devices, is evolving into edge intelligence by…
An international team of scientists has developed a novel way to experimentally produce plasma ‘fireballs’ on Earth. Black holes and neutron stars are among the densest known objects in the universe. Within and around these extreme astrophysical environments exist plasmas, the fourth fundamental state of matter alongside solids, liquids, and gases. Specifically, the plasmas at these extreme conditions are known as relativistic electron-positron pair plasmas because they comprise a collection of electrons and positrons—all flying around at nearly the speed…
Deep connections in the nano world… In relationships, sharing closer spaces naturally deepens the connection as bonds form and strengthen through increasing shared memories. This principle applies not only to human interactions but also to engineering. Recently, an intriguing study was published demonstrating the use of quantum dots to create metasurfaces, enabling two objects to exist in the same space. Professor Junsuk Rho from the Department of Mechanical Engineering, the Department of Chemical Engineering, and the Department of Electrical Engineering,…
Physicists at TU Graz have calculated how suitable molecules can be stimulated by infrared light pulses to form tiny magnetic fields. If this is also successful in experiments, the principle could be used in quantum computer circuits.

The road to innovative operation scenarios for fusion power plants. Fusion energy is that released when two light nuclei combine to form a single heavier one (nuclear fusion reaction). Fusion energy-based power generation (fusion power plant) uses the energy generated when deuterium and tritium combine to form helium. A nuclear fusion reaction does not produce carbon dioxide. In addition, since it is possible to extract deuterium and tritium from the sea water, fusion energy is regarded as a sustainable energy…
A study by the University of Bonn gives novel insight into properties which are often difficult to observe. Thousands of particles of light can merge into a type of “super photon” under suitable conditions. Physicists call such a state a photon Bose-Einstein condensate. Researchers at the University of Bonn have now shown that this exotic quantum state obeys a fundamental theorem of physics. This finding now allows one to measure properties of photon Bose-Einstein condensates which are usually difficult to…
A rare exoplanet that should have been stripped down to bare rock by its nearby host star’s intense radiation somehow grew a puffy atmosphere instead—the latest in a string of discoveries forcing scientists to rethink theories about how planets age and die in extreme environments. Nicknamed “Phoenix” for its ability to survive its red giant star’s radiant energy, the newly discovered planet illustrates the vast diversity of solar systems and the complexity of planetary evolution—especially at the end of stars’…
