Grasping the precise energy landscapes of quantum particles can significantly enhance the accuracy of computer simulations for material sciences. These simulations are instrumental in developing advanced materials for applications in physics, chemistry, and sustainable technologies. The research tackles longstanding questions from the 1980s, paving the way for breakthroughs across various scientific disciplines. An international group of physicists, led by researchers at Trinity College Dublin, has developed new theorems in quantum mechanics that explain the “energy landscapes” of quantum particle collections. Their work resolves decades-old questions, paving the way for more accurate computer simulations of materials. This advancement could significantly aid scientists in designing materials poised to revolutionize green technologies. #quantum #simulation #green #materials https://lnkd.in/gsEbJkDU

Researchers have discovered magnetic monopoles – isolated magnetic charges – in a material closely related to rust, a result that could be used to power greener and faster computing technologies. Researchers led by the University of Cambridge used a technique known as diamond quantum sensing to observe swirling textures and faint magnetic signals on the surface of hematite, a type of iron oxide. The research has also shown the direct connection between the previously hidden swirling textures and the magnetic charges of materials like hematite, as if there is a secret code linking them together. The results could be useful in enabling next-generation logic and memory application. An alternative strategy to find monopoles involves the concept of emergence. The idea of emergence is the combination of many physical entities can give rise to properties that are either more than or different to the sum of their parts. The Cambridge researchers used emergence to uncover monopoles spread over two-dimensional space, gliding across the swirling textures on the surface of a magnetic material. For the current study, the researchers used the technique to look at hematite, an antiferromagnetic iron oxide material. To their surprise, they found hidden patterns of magnetic charges within hematite, including monopoles, dipoles, and quadrupoles. These monopoles are a collective state of many spins that twirl around a singularity rather than a single fixed particle, so they emerge through many-body interactions. The result is a tiny, localized stable particle with diverging magnetic field coming out of it. The study not only highlights the potential of diamond quantum magnetometry but also underscores its capacity to uncover and investigate hidden magnetic phenomena in quantum materials. If controlled, these swirling textures dressed in magnetic charges could power super-fast and energy-efficient computer memory logic. We may soon have to rewrite physics text books. #climatechange #monopoles #supercomputers #aiml #iiot #nonvolatilememory

The CERN Accelerator School holds training courses on accelerator physics! At CERN the scientists did not have a Scientific Discovery in 60 years! “All physicists, the greatest scientists, the Nobel Laureates…do Not understand particles collisions” Adrian Ferent Some examples: “As the nuclei travel faster and faster, their surrounding fields are squished into disks, making them much more concentrated. When two lead ions pass closely enough that their electromagnetic fields swoosh through one another, the high-energy photons which ultimately make up these fields can interact.” https://lnkd.in/dTn_PvCb Here is another example: James Beacham is a post-doctoral researcher at CERN with the Ohio State University https://lnkd.in/dw56hwnw James Beacham said that Dark Matter is not inside the proton, the protons come close enough and “feel each other”… Another funny explanation: “When two protons graze each other, their squished electromagnetic fields intersect. These fields skip the classical “amplify” etiquette that applies at low energies and instead follow the rules outlined by quantum electrodynamics. Through these new laws, the two fields can merge and become the “E” in E=mc².” Another example: “In particle physics, the term “collide” can mean that two protons glide through each other, and their fundamental components pass so close together that they can talk to each other. If their voices are loud enough and resonate in just the right way, they can pluck deep hidden fields that will sing their own tune in response—by producing new particles.” Another example: “We're focusing on an electron and a positron interacting with one another at high energies.  One thing that can result from such an interaction is the production of a pair of W bosons. There's the conventional way you would think about this as a sequence of images – the electron-positron pair getting closer and closer until, ultimately, something happens, the electron-positron pair vanishes, and the W bosons simply materialize” https://lnkd.in/deGCN4Ez In Ferent Quantum Gravity: “The electron is a photon around Ferent Matter” Adrian Ferent “Particles collisions are photons collisions” Adrian Ferent

🖥 Researchers Improve Magnets for Computing 🖥 Srinivasa Singamaneni, Ph.D., associate professor in the Department of Physics at The University of Texas at El Paso asks: "How can we design new materials so that they can store data with less volume, less cost and using less power?" ❓Is the answer in a new type of magnet? 2D magnets have been said to have serious potential in the computing world because of their tiny size, however Van der Waals magnets have only ever worked at temperatures below freezing, until now... By adding a low-cost organic material (known as tetrabutylammonium) between the magnet's atomic layers, this allows the magnet to work in temperatures of up to 170 degrees Fahrenheit. 📈 Pushing boundaries of 2D magnetism; yet another huge step for the industry. Here at The Magnetics Show, we are huge advocates of incredible scientific advancements such as these and are continuously impressed at the versatility of magnetics. 👏 Kudos to SRINIVASA RAO SINGAMANENI and team of scientists from Stanford University, The University of Edinburgh, Los Alamos National Laboratory, the National Institute of Standards and Technology (NIST) and Brookhaven National Laboratory! 👏 Read article here: https://lnkd.in/e6kkSXN3 Read journal article on van der Waals magnet: https://lnkd.in/e55epJzm #magnetics #magnetism #magnet #2dmaterials #MagShowUS

I have just completed my first year as a PhD student in the Quantum Science and Engineering Program of the University of Delaware. During my first semester, I learned the fundamental principles of Quantum Computation and Quantum Information Science from professors like Prof. Mariana Safronova, who took us through the rudiments of quantum information science. I also took courses that introduced me to the fundamentals of quantum hardware, in which Prof. Vishal Saxena taught us the basic principles of every known quantum bit architecture, from superconducting circuits to photonics to algorithms for quantum error correction. I also took courses in professional skills, which enabled me to understand quantum not only from an academic perspective but from a professional perspective as value creation in the quantum industry. In my second semester, given my track of study (Quantum nanotechnology), I took courses that were rooted in the basic principles of nanofabrication methodologies and concepts in solid-state materials. These courses enabled me to understand the device architecture for Quantum information technology. In the STAQ Quantum Ideas Summer School, I will be learning the fundamental and advanced principles of Quantum Information Science, Quantum algorithms, and Quantum computations from well-renowned scientists both in academia and industries in the United States. Using this feedback, I intend to inform my research questions with a better understanding of the principles of Quantum Information Science. #QuantumInformationScience #QuantumAdvantage #QuantumIdeasSummerSchool #Photonics #Semiconductor #Nanofabrication Afam Daniel Madu

MIT researchers and colleagues recently discovered an important — and unexpected — electronic property of graphene, a material discovered only about 17 years ago that continues to surprise scientists with its interesting physics. The work, which involves structures composed of atomically thin layers of materials that are also biocompatible, could usher in new, faster information-processing paradigms. One potential application is in neuromorphic computing, which aims to replicate the neuronal cells in the body responsible for everything from behavior to memories. #altertechno #peterckh #graphene
