Exciting breakthrough in dark matter research! Scientists have discovered a new method to track ultrafine dark matter particles in Earth's ionosphere, challenging the notion that dark matter is completely invisible. These particles, millions of times lighter than electrons, could be leaving traces in low-frequency radio waves, offering a promising avenue for detection. If validated, this discovery could revolutionize our understanding of dark matter's nature and confirm theories about its existence.

For the first time, Massachusetts Institute of Technology scientists have made a monumental breakthrough in the physics of superfluid quantum gas, unveiling the phenomenon known as 'Second Sound' through a novel imaging technique. This discovery, published in Science Magazine, marks a pivotal moment in our comprehension of how heat behaves in extreme quantum states. Unlike traditional materials where heat spreads outward, superfluid quantum gases exhibit a unique behavior where heat "sloshes" side to side, propagating as a wave. This contradicts our conventional understanding and opens up new possibilities for exploring the physics of high-temperature superconductors and the enigmatic interiors of neutron stars. https://lnkd.in/gGDunYzY

📃Scientific paper: Simulating Electromagnetic Cascades with Lorentz Invariance Violation Abstract: Lorentz invariance violation (LIV) is a phenomenon featuring in various quantum gravity models whereby Lorentz symmetry is broken at high energies, potentially impacting the behaviour of particles and their interactions. Here we investigate the phenomenology of LIV within the context of gamma-ray-induced electromagnetic cascades. We conduct detailed numerical simulations to explore the expected manifestations of LIV on gamma-ray fluxes, taking into account relevant effects such as pair production and inverse Compton scattering. Additionally, we consider processes forbidden in the Standard Model, namely vacuum Cherenkov emission and photon decay. Our analysis reveals that these modifications result in distinct characteristics within the measured particle fluxes at Earth, which have the potential to be observed in high-energy gamma-ray observations. ;Comment: 17 pages, 9 figures Continued on ES/IODE ➡️ https://etcse.fr/jhC ------- If you find this interesting, feel free to follow, comment and share.

📃Scientific paper: Constraints on the spectral signatures of superconducting cosmic strings Abstract: If they exist, networks of superconducting cosmic strings are capable of injecting copious amounts of electromagnetic energy into the background over a broad range of frequencies. We study this injection both analytically, as well as numerically using the thermalization code CosmoTherm. With our refined analytic formalism, we update constraints from CMB spectral distortions by following the injection of entropy, as well as energy, on the amplitude of the $\mu$-distortion, leading to a significant improvement in those limits. Furthermore, we utilize the full shape of the distorted spectrum from CosmoTherm to include constraints from non-$\mu$, non-$y$ type distortions. Additionally, we use the outputs for the ionization history and global 21cm signal to derive and update constraints on string model parameters using measurements from other datasets. Analysis of CMB anisotropies provides the most stringent constraints, though with a slightly modified shape and strength when compared to previous results. Modifications of the reionization history provide new bounds in the high current domain, and we also find that the observations of the low-frequency radio background probe a small region of parameter space not explored by other datasets. We also analyze global $21$-cm constraints, and find that the inclusion of soft photon heating plays a crucial role, essentially removing any constraints in the considered parameter domain.

Scientists now believe time is an illusion, a construct of quantum entanglement rather than a fundamental aspect of reality. This groundbreaking theory suggests that our perception of time is due to the entanglement of objects with a reference clock. The research, published in Physical Review A, challenges traditional notions of time and opens new avenues for understanding the universe through quantum mechanics. While still in its early stages, this theory could revolutionize our comprehension of time. #QuantumMechanics #Science #TimeIllusion https://lnkd.in/gjRCuAvb

U.S. Department of Energy (DOE) looks at quantum vortexes. This research challenges long-standing theories in quantum chromodynamics (QCD) by revealing that quark liquids differ fundamentally from nucleon liquids due to the unique “color-magnetic field” in their vortices, a phenomenon not observed in nucleon liquids. https://lnkd.in/ewGR-k7A
