Removing the Spookiness…
Conceptual artwork of a pair of entangled quantum particles. Credit: Science Photo Library/Alamy Stock Photo Topics: Modern Physics, Particle Physics, Quantum Mechanics, Theoretical Physics Quantum entanglement is a complex phenomenon in physics that is usually poorly described as an invisible link between distant quantum objects that allows one to instantly affect the other. Albert Einstein famously dismissedContinue reading “Removing the Spookiness…”
Spooky Action Between Friends…
Credit: Petrovich9/Getty Images Topics: Entanglement, Particle Physics, Quantum Mechanics, Research, Theoretical Physics Reference: Albert Einstein colorfully dismissed quantum entanglement—the ability of separated objects to share a condition or state—as “spooky action at a distance.” Science.org For the first time, scientists have observed quantum interference—a wavelike interaction between particles related to the weird quantum phenomenon of entanglement—occurring betweenContinue reading “Spooky Action Between Friends…”
Rule Breakers…
Credit: Matt Harrison Clough (original image at link) Topics: Entanglement, High Energy Physics, Particle Physics, Quantum Mechanics Breaking the rules is exciting, especially if they have been held for a long time. This is true not just in life but also in particle physics. Here the rule I’m thinking of is called “lepton flavor universality,”Continue reading “Rule Breakers…”
DUNE Detector…
Topics: Applied Physics, Modern Physics, Particle Physics, Theoretical Physics The Deep Underground Neutrino Experiment (DUNE) will be the world’s largest cryogenic particle detector. Its aim is to study the most elusive of particles: neutrinos. Teams from around the world are developing and constructing detector components that they will ship to the Sanford Underground Research Facility,Continue reading “DUNE Detector…”
Weighty W…
Topics: Fermilab, High Energy Physics, Modern Physics, Particle Physics, Steven Weinberg The most precise measurement to date of the mass of the W boson has yielded a result seven standard deviations away from that predicted by the Standard Model of particle physics. The stunning result was obtained by a painstaking analysis of data taken atContinue reading “Weighty W…”
DUNE…
Topics: Fermilab, High Energy Physics, Modern Physics, Neutrinos, Particle Physics Solving big mysteries The Deep Underground Neutrino Experiment is an international flagship experiment to unlock the mysteries of neutrinos. DUNE will be installed in the Long-Baseline Neutrino Facility, under construction in the United States. DUNE scientists will paint a clearer picture of the universe and how itContinue reading “DUNE…”
Vortex Beams…
Topics: Bose-Einstein Condensate, Nanotechnology, Particle Physics, Quantum Optics A wave-like property previously only seen in beams of light and electrons has been observed for the first time in atoms and molecules. By passing beams of helium and neon through a grid of specially shaped nanoslits, researchers led by Edvardas Narevicius of Israel’s Weizmann Institute of Science succeededContinue reading “Vortex Beams…”
Dielectric Laser Accelerators…
Topics: Applied Physics, Modern Physics, Particle Physics Physics Today 74, 8, 42 (2021); https://doi.org/10.1063/PT.3.4815 Particle accelerators are among the most important scientific tools of the modern age. Major accelerator facilities, such as the 27-km-circumference Large Hadron Collider in Switzerland, where the Higgs boson was recently discovered, allow scientists to uncover fundamental properties of matter and energy. ButContinue reading “Dielectric Laser Accelerators…”
Collider Neutrinos…
Topics: CERN, High Energy Physics, Particle Physics, Research Think “neutrino detector” and images of giant installations come to mind, necessary to compensate for the vanishingly small interaction probability of neutrinos with matter. The extreme luminosity of proton-proton collisions at the LHC, however, produces a large neutrino flux in the forward direction, with energies leading toContinue reading “Collider Neutrinos…”
