#Fusion_Energy marks a revolutionary step forward with #sustainable resources available on the Earth. When #Deuterium (²H) and #Tritium (³H), isotopes of #Hydrogen, react, they produce #Helium (⁴He) and a free #Neutron (n). The total mass of "D + T" is greater than that of "He," and according to #Einstein's formula (E = mc²), the difference in mass converts into energy. This tremendous energy and fusion ignition was first achieved in human history at Lawrence Livermore National Laboratory’s National Ignition Facility (#NIF) by Tammy Ma and her team. As there is no carbon involved in this reaction, fusion represents a #Clean_Energy source, with potential applications such as large-scale #Carbon_Capture to combat #Climate_Change.

Asymptotic Freedom in QCD and fine structure constant in high energy calculation using qGUT(gravity included) https://lnkd.in/gT7RD4hn Asymptotic freedom, a fundamental property of Quantum Chromodynamics (QCD), elucidates the decreasing strength of the strong nuclear force at high energy scales, enabling quarks and gluons to behave as nearly free particles. This phenomenon plays a crucial role in understanding particle interactions at extreme conditions, such as those found in high-energy colliders and the early universe. Integrating this principle into quantum Grand Unified Theories (qGUT), we explore the energy-dependence of the strong coupling constant and its implications for gauge unification. A key outcome of this study is the increasing fine-structure constant at high energy levels, reflecting the stronger electromagnetic interaction strength when incorporating qGUT frameworks. This work discusses the mathematical formalism bridging QCD asymptotic freedom with qGUT scenarios, providing a cohesive understanding of the interplay between gravity,strong, weak, and electromagnetic forces in high-energy regimes. The results offer significant implications for particle physics, shedding light on unification models and the energy thresholds where fundamental forces converge.

After painstakingly thorough work, I am pleased to see our new paper, led by Andre Scaffidi, out today as part of the DARWIN direct dark matter detection collaboration! 👏 We use a semi-supervised anomaly detection pipeline, comprising of a variational autoencoder trained on simulated background events and a classifier distinguishing between electronic and nuclear recoils, to demonstrate new physics searches at future direct detection experiments - here focusing on DARWIN. This enables us to look for `anomalous signals' (ie, unexpected under the background simulations) in a physics-independent manner. Our approach improves sensitivity with respect to a likelihood-based method, while remaining model-agnostic. Check out the paper here: https://lnkd.in/dv-f5NDB

CI Compass recently published Chris Bontempi's "Network for Advanced NMR Use Cases" document. Bontempi is the Director of IT for the National Science Foundation (NSF)-funded Network for Advanced NMR project, which includes The University of Connecticut Health Center, the University of Wisconsin-Madison NMRFAM facility, and The University of Georgia CCRC facility, which operate ultra-high field Nuclear Magnetic Resonance (NMR) spectrometers. This document highlights challenges involved in harvesting key information from scientific instruments spread across a wide geographical area with complex ownership concerns and diverse driers of interest. It summarizes some general considerations that help frame our discussion on modern research data infrastructures and strategies to enable open data. 📖 Read the document here: https://lnkd.in/gsy9Q3QM

Lately I've been into the symmetry breaking in quantum field theory. Now to put it briefly symmetry breaking gives way to how fermions acquire mass, by taking the complex lagrangian that obeys the Klein-Gordon equation, fiddling with the potential term and finding the minima, solving for the vacuum expectation value, and expanding the field around it vacuum expectation value, substituting everything and finding the mass term. The definition of mass here is rather an illusion, from the graphical perspective, plotting the potential against the field, we have the stationary point or rather, the false vacuum point at 0, then we have our two left and right minima(s). At zero point the mass is an illusion, with a imaginary number that represents instability, as soon as the symmetry is broken, the symmetry no longer looks the same, having left and right vacuum expectation value, the inability of the particle to move up to the zero point or point of instability is what we call mass. Before the SSB (spontaneous symmetry Breaking) fermions particularly the lepton category (electrons and neutrinos) were both massless , electrons existed as both left-handed and right-handed fermions, neutrinos existed only as left-handed fermions, the very origin of left-handed doublets and right-handed Singlets, and they both enjoyed the u(1) and u(2) symmetry, the more reason we have photons as u(1) bosons and the su(2) weak force interaction of gluons on the quarks that makes up the nucleus of the atom, which aids in nuclear reactions, radioactive decays etc. After the symmetry breaking, the symmetry of the electromagnetic force and weak nuclear force, aided by photons and gluons, broke into w± and z bosons(force carries). With particles having mass and the emergence of the Higgs mechanism, the prime giver of mass to fermions.

The 2024 Optica Laser Conference and Exhibition (https://lnkd.in/gTfhGdw9) was held last month in Osaka, Japan. This is a major international gathering for those in the optics and photonics industry, with particular focus on high power, solid state and fiber laser engineering and its versatile applications. HB11's Head of R & D, Dr Sergey Pikuz (pic.), was invited to speak on the use of Lasers for Fusion energy - specifically HB11's middle and long-term vision for such use. Sergey spoke about the important areas of progress in laser engineering, how they are crucial for making fusion economically viable, and how this is reflected in the HB11 Energy program. A key presentation at the conference was a plenary talk by Tammy Ma from the Lawrence Livermore National Laboratory (LLNL). Tammy discussed the views of the U.S. National Nuclear Security Administration (Department of Energy) with regard the next steps in fusion energy. This follows the milestone of LLNL achieving ignition, reaching 5 MJ of fusion energy yield. #fusionenergy, #cleanenergy, #protonboron, #boron, #hydrogenenergy #fusion, #laserfusion, #laserenergy, #lasertechnology #scienceandtechnology, #plasma, #InertialFusionEnergy #InertialConfinementFusion, #alphaparticle, #aneutronic
