Microscopic imaging of magnetic fields, enabled by quantum sensing, allows the measurement of the unique magnetic fingerprint of objects. This opens the door for fundamentally new applications in various fields such as materials testing or biomedicine. Fraunhofer IAF has developed an innovative method using fast camera images in the form of an improved wide-field magnetometer. The system offers a unique compromise of sensitivity, resolution and speed. It will be presented at LASER World of QUANTUM 2023 as part of the…
Princeton researchers used data from NASA’s Parker Solar Probe to deduce that a catastrophic event likely created the prolific Geminids meteoroid stream. The Geminids meteoroids light up the sky as they race past Earth each winter, producing one of the most intense meteor showers in our night sky. Mysteries surrounding the origin of this meteoroid stream have long fascinated scientists because, while most meteor showers are created when a comet emits a tail of ice and dust, the Geminids stem…
There is a clear statistical correlation between global seismic activity and changes in the intensity of cosmic radiation recorded at the surface of our planet, potentially helping to predict earthquakes. Surprisingly, it exhibits a periodicity that escapes unambiguous physical interpretation. Strong earthquakes usually result in many human casualties and huge material losses. The scale of the tragedy could be significantly reduced if we had the ability to predict the time and place of such cataclysmic events. The CREDO project, initiated in…
Jupiter’s moon, Europa, is slightly smaller than Earth’s Moon and is one of the most promising places to search for alien life. Amid the Jovian system, Europa is of particular interest to scientists because of the strong evidence for nutrients, water and energy to potentially provide a habitable environment for some form of life beyond Earth. In addition, Europa is believed to be made up into four layers (from surface to center): an ice shell, salt water ocean, rocky mantle,…
… an anomalous phenomenon found. In a paper published in Nature Photonics, the research team from the Center for Quantum Information and Communication – Ecole polytechnique de Bruxelles of Université libre de Bruxelles, has found an unexpected counter-example to common knowledge on photon bunching. One of the cornerstones of quantum physics is Niels Bohr’s complementarity principle, roughly speaking the fact that objects may behave either like particles or like waves. These two mutually exclusive descriptions are well illustrated in the…
The discovery of a rare type of star system in two independent studies by the University of Warwick and the Leibniz Institute for Astrophysics Potsdam (AIP) provides new insights into the dynamo model’s predictions for stellar evolution. The new white dwarf pulsar, an extremely close binary system of a white dwarf star and a red dwarf star that together would fit inside the Sun, is only the second known of its kind. White dwarfs are extremely dense stellar remnants with…
An international team including a University of Washington scientist has found that the water on one of Saturn’s moons harbors phosphates, a key building block of life. The team led by the Freie Universität Berlin used data from NASA’s Cassini space mission to detect phosphates in particles ejected from the ice-covered global ocean of Saturn’s moon Enceladus. Phosphorus, in the form of phosphates, is vital for all life on Earth. It forms the backbone of DNA and is part of…
“Chiral bose-liquid state” is a new phase of matter, according to UMass Amherst professor. A team of physicists, including University of Massachusetts assistant professor Tigran Sedrakyan, recently announced in the journal Nature that they have discovered a new phase of matter. Called the “chiral bose-liquid state,” the discovery opens a new path in the age-old effort to understand the nature of the physical world. Under everyday conditions, matter can be a solid, liquid or gas. But once you venture beyond…
Research led by Chemnitz University of Technology reveals electronic defect landscape in organic solar cells and describes the density of states of these cells for the first time using a power law – publication in the prestigious journal Physical Review Letters. Researchers from the Professorship of Optics and Photonics of Condensed Matter (headed by Prof. Dr. Carsten Deibel) of Chemnitz University of Technology and other partner institutions are currently intensively working together on solar cells made of novel organic semiconductors,…
Discovering ‘axions’ could help answer one of the most puzzling questions in physics. One of the most high-profile mysteries in physics today is what scientists refer to as the “Strong CP Problem.” Stemming from the puzzling phenomenon that neutrons do not interact with electric fields despite being made up of quarks—smaller, fundamental particles that carry electric charges—the Strong CP Problem puts into question the Standard Model of physics, or the set of theories scientists have been using to explain the…
An international research team has succeeded for the first time in measuring the electron spin in matter – i.e., the curvature of space in which electrons live and move – within “kagome materials“, a new class of quantum materials. The results obtained – published in Nature Physics – could revolutionise the way quantum materials are studied in the future, opening the door to new developments in quantum technologies, with possible applications in a variety of technological fields, from renewable energy to biomedicine, from electronics to quantum computers. Success was achieved by an international…
A new approach to optical communication that can be deployed with conventional technology. The patterns of light hold tremendous promise for a large encoding alphabet in optical communications, but progress is hindered by their susceptibility to distortion, such as in atmospheric turbulence or in bent optical fibre. Now researchers at the University of the Witwatersrand (Wits) have outlined a new optical communication protocol that exploits spatial patterns of light for multi-dimensional encoding in a manner that does not require the patterns…
An international research team makes a breakthrough in physics. An international team led by researchers at Nankai University in China and at University of Zagreb in Croatia, along with team at the Institut national de la recherche scientifique (INRS) in Canada, led by Roberto Morandotti has made an important breakthrough in the study of topological phases. Their findings were recently published in Nature Physics – a journal published by Nature Publishing Group. In the last decade, topological photonics has attracted increasing…
… and further new developments at Laser World of Photonics. At the Munich trade show, the Ferdinand-Braun-Institut will be exhibiting, among other things, a robotic arm with a novel direct diode laser system for 3D printing. It will also present its diode laser and UV-LED portfolio – with advances in chip technology as well as modules and systems. Once again, the Ferdinand-Braun-Institut, Leibniz-Institut für Höchstfrequenztechnik (FBH) will present its complete range of services at Laser World of Photonics in Munich…
New simulations suggest, for the first time, that cocoons of debris around dying stars likely emit gravitational waves Cocoons form as a massive star sheds debris while collapsing into a black hole LIGO might be able to detect these gravitational waves from cocoons in upcoming runs So far, astrophysicists have only detected gravitational waves from binary systems — the mergers of either two black holes, two neutron stars or one of each. Although astrophysicists theoretically should be able to detect…
Researchers have detected complex organic molecules in a galaxy more than 12 billion light-years away from Earth – the most distant galaxy in which these molecules are now known to exist. Thanks to the capabilities of the recently launched James Webb Space Telescope and careful analyses from the research team, a new study lends critical insight into the complex chemical interactions that occur in the first galaxies in the early universe. University of Illinois Urbana-Champaign astronomy and physics professor Joaquin…
