The Fourth Industrial Revolution is driving exponential growth in data transmission, and cost-effective, ultrafast, and compact optical communication technologies are urgently needed to manage the exploding data transmission volume. Vortex beams, which exhibit a swirling shape around the axis of propagation, have the potential to increase the amount of informatioon that can be stored at the same frequency. As such they represent a promising avenue for the development of high-capacity optical communication technologies that surpass 5G and pave the way…

What they can mean for climate science, geology, and driverless cars? Atomic clocks guarantee unrivalled precision when it comes to tracking time. They help us keep our digital and analogue clocks running on time by measuring the atomic resonance in cesium atoms exposed to microwave radiation. A new generation of optical atomic clocks is now set to increase their precision by a factor of up to 100,000 by measuring higher frequencies in the near IR and visible light range. Fraunhofer…

Physicists at the Universities of Jena and Central Florida investigate light with negative temperatures. In the issue of the renowned journal Science published today (10.3.23), the team led by Prof. Dr Ulf Peschel reports on measurements on a sequence of pulses that travel thousands of kilometres through glass fibres that are only a few microns thin. The researchers were surprised by the results. “We have found that the light pulses organize themselves after about a hundred kilometres and then behave more…

Findings provide evidence for ‘deconfinement’ and insight into seething temperature of the hottest matter on Earth. Scientists using the Relativistic Heavy Ion Collider (RHIC) to study some of the hottest matter ever created in a laboratory have published their first data showing how three distinct variations of particles called upsilons sequentially “melt,” or dissociate, in the hot goo. The results, just published in Physical Review Letters, come from RHIC’s STAR detector, one of two large particle tracking experiments at this U.S. Department of Energy (DOE)…

Physicists led by Prof Raphael Wittkowski and Prof Uwe Thiele from the Institute of Theoretical Physics at the University of Münster has developed a new model for the dynamics of systems consisting of many self-propelled particles. The study of active particles is one of the fastest-growing areas of physics. With „active particles“ physicists refer to objects which move by themselves as a result of internal self-propulsion. These include living things such as bacteria and fish swimming, birds flying or humans…

Students test new space technologies under space conditions. If all goes as planned, a rocket will be launched from Cape Canaveral to the International Space Station at 2:30 p.m. on Wednesday, March 15, 2023. A ferrofluid experiment of the student small satellite group (KSat) of the University of Stuttgart will be on board. This experiment will be conducted in space for around four weeks. The aim of the experiment is to find out how to replace mechanical parts such as switches with…

How does an iPhone predict the next word you’re going to type in your messages? The technology behind this, and also at the core of many AI applications, is called a transformer; a deep-learning algorithm that detects patterns in datasets. Now, researchers at EPFL and KAIST have created a transformer for Metal-Organic Frameworks (MOFs), a class of porous crystalline materials. By combining organic linkers with metal nodes, chemists can synthesize millions of different materials with potential applications in energy storage and gas…

Black holes become active and grow by consuming gas captured from other galaxies. This is the finding of a new study from University of Copenhagen researchers, and shows a clear connection between the evolution of supermassive black holes and galactic interaction. In the outer regions of the Milky Way, our blue planet rotates in its orbit around the Sun, the massive center of our Solar System. 26,000 light-years away, a supermassive black hole known as Sagittarius A* is at the…

New high-speed super-resolution imaging technique resolves a longstanding contradiction between spatial resolution and imaging speed. As an indispensable tool for observing the microcosmos, optical microscopy has boosted the development of various fields, including biology, medicine, physics, and materials. However, optical diffraction imposes a spatial resolution restriction on optical microscopy, which hampers exploration of finer structures. To overcome the resolution limitation, various super-resolution microscopy techniques based on diverse principles have been proposed. Yet these techniques commonly acquire super-resolution at the expense…

… back to the interstellar medium. Observations of water in the disk forming around protostar V883 Ori have unlocked clues about the formation of comets and planetesimals in our own Solar System. Scientists studying a nearby protostar have detected the presence of water in its circumstellar disk. The new observations made with the Atacama Large Millimeter/submillimeter Array (ALMA) mark the first detection of water being inherited into a protoplanetary disk without significant changes to its composition. These results further suggest…

A new method for predicting the behavior of quantum devices provides a crucial tool for real-world applications of quantum technology. Researchers have found a way to predict the behavior of many-body quantum systems coupled to their environment. The work represents a way to protect quantum information in quantum devices, which is crucial for real-world applications of quantum technology. In a study published in Physical Review Letters, researchers at Aalto University in Finland and IAS Tsinghua University in China report a…

European team of autonomous robots explores lava cave in Lanzarote. As potential locations for future base camps, the lava caves on the moon are of great interest. But how can they be reached and explored? This has been investigated by a European consortium coordinated by the German Research Center for Artificial Intelligence (DFKI) in the project CoRob-X funded by the European Commission. In a final analog mission on Lanzarote, the project partners have now succeeded in proving the feasibility of…

Researchers at ETH Zurich and TII Abu Dhabi, with the support of quantum optics theorists from Innsbruck, Austria, have succeeded in simultaneously cooling the motion of a tiny glass sphere in two dimensions to the quantum ground-state. This represents a crucial step towards a 3D ground-state cooling of a massive object and opens up new opportunities for the design of ultra-sensitive sensors. Glass nanoparticles trapped by lasers in extreme vacuum are considered a promising platform for exploring the limits of…

AI4Mobile boosts performance for industry and transport. The research project AI4Mobile (AI-supported mobile communication systems for mobility in industry and transport) has successfully come to an end. Led by the Fraunhofer Heinrich-Hertz-Institut (HHI), researchers of the AI4Mobile consortium have worked on the development of AI-based communication solutions for various mobility applications within this project since 2020.

Tubular nanomaterial of carbon makes ideal home for spinning quantum bits. Scientists find that a tubular nanomaterial of carbon makes for ideal host to keep quantum bits spinning in place for use in quantum information technologies. Scientists are vigorously competing to transform the counterintuitive discoveries about the quantum realm from a century past into technologies of the future. The building block in these technologies is the quantum bit, or qubit. Several different kinds are under development, including ones that use…
