Transport networks are integral to a wide array of systems in nature, ranging from biological entities like jellyfish to electrical infrastructures and even climatic phenomena. These networks serve crucial functions, from facilitating the flow of nutrients and oxygen in organisms to channeling electrical discharges during storms. One significant feature of many transport networks is the
The field of nuclear physics has long been fascinated with the concept of “magic numbers,” which refer to specific numbers of protons or neutrons in a nucleus that result in particularly stable configurations. One such magic number, the neutron number 50, has captured the attention of researchers due to its significant implications for our understanding
The field of quantum technology is continually evolving, unveiling new materials and methods that defy conventional understanding. An innovative development led by researchers from TU Dresden sheds light on the potential of extremely thin materials, composed of only a few atomic layers, which promise groundbreaking applications in electronics and quantum technologies. The recent experiment carried
When ultrafast electrons are deflected, they emit light—known as synchrotron radiation. This light is utilized in storage rings, where magnets compel the particles onto a closed path, generating longitudinally incoherent light with a broad wavelength spectrum. While monochromators can extract individual wavelengths from the spectrum, the radiant power is significantly reduced to just a few
Supersymmetry (SUSY) is an intriguing theory in particle physics that offers solutions to some of the mysteries still lingering in the field. It proposes the existence of “superpartners” for all known particles, each with distinct properties. For instance, the top quark from the Standard Model would have a superpartner known as the “stop.” In 2021,
Quantum computers are on the brink of revolutionizing the computing world due to their ability to conduct complex calculations in a fraction of the time it would take a traditional computer. One key element in the development of an efficient quantum computer is the quantum bit, or qubit, which must maintain coherence for a significant
The recent study published in Nature Communications led by Rice University’s Qimiao Si delves into the world of quantum materials and the potential impact of flat electronic bands at the Fermi level. Quantum mechanics governs these materials, where electrons exist in unique energy states, forming a ladder with the highest rung being the Fermi energy.
The pursuit of accurately simulating quantum particles using a computer made up of quantum particles has been a long-standing goal for physicists. The recent collaboration between scientists at Forschungszentrum Jülich and colleagues from Slovenia has made significant progress in this area. By using a quantum annealer to model real-life quantum material, they have demonstrated the
Recent studies by researchers at the University of Waterloo and Universidad Complutense de Madrid have challenged the long-standing theory of “kugelblitze,” black holes formed by intense concentrations of light. In their research titled “No black holes from light,” published on the arXiv preprint server and forthcoming in Physical Review Letters, the team debunks the possibility
Researchers at the Legnaro National Laboratory have delved into the intricacies of the transfer of neutrons in weakly bound nuclei. The focus of their experiment revolved around the one-neutron stripping process in reactions involving lithium-6 and bismuth-209. This recent study, detailed in the journal Nuclear Science and Techniques, sheds light on the dynamics of nuclear
Electron-phonon coupling plays a significant role in the phenomenon of superconductivity, where materials exhibit resistance-free electrical conductance. The interaction between electrons and vibrations in a lattice, known as phonons, is crucial for the formation of Cooper pairs. These pairs of electrons are bound together via attractive interactions and condense into a coherent state, leading to
