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…”

Aharonov-Bohm Effect…

Topics: General Relativity, Gravity, Modern Physics, Quantum Mechanics The idea that particles can feel the influence of potentials even without being exposed to a force field may seem counterintuitive, but it has long been accepted in physics thanks to experimental demonstrations involving electromagnetic interactions. Now physicists in the US have shown that this so-called Aharonov-BohmContinue reading “Aharonov-Bohm Effect…”

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…”

Deux Ex Machina…

Topics: Condensed Matter Physics, Modern Physics, Quantum Mechanics The existence of ghost hyperbolic surface polaritons has been demonstrated by an international collaboration including researchers in China and the US. Based at Huazhong University of Science and Technology (HUST), National University of Singapore (NUS), National Center for Nanoscience and Technology (NCNST), and the City University ofContinue reading “Deux Ex Machina…”

Double Slit…

Topics: Modern Physics, Quantum Mechanics, Theoretical Physics One of the most counterintuitive concepts in physics – the idea that quantum objects are complementary, behaving like waves in some situations and like particles in others – just got a new and more quantitative foundation. In a twist on the classic double-slit experiment, scientists at Korea’s InstituteContinue reading “Double Slit…”

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…”

Nearing Ignition…

Topics: Energy, Environment, Modern Physics, Nuclear Fusion, Nuclear Power More than a decade ago, the world’s most energetic laser started to unleash its blasts on tiny capsules of hydrogen isotopes, with managers promising it would soon demonstrate a route to limitless fusion energy. Now, the National Ignition Facility (NIF) has taken a major leap toward thatContinue reading “Nearing Ignition…”

Muon g-2…

Topics: Modern Physics, Particle Physics, Quantum Mechanics Solving a mystery More than 200 scientists from around the world are collaborating with Fermilab on the Muon g-2 physics experiment which probes fundamental properties of matter and space. Muon g-2 (pronounced gee minus two) allows researchers to peer into the subatomic world to search for undiscovered particlesContinue reading “Muon g-2…”

Quantum Jumps…

Topics: Modern Physics, Quantum Mechanics, Theoretical Physics Quantum mechanics, the theory that describes the physics of the universe at very small scales, is notorious for defying common sense. Consider, for instance, the way that standard interpretations of the theory suggest change occurs in the quantum turf: shifts from one state to another supposedly happen unpredictablyContinue reading “Quantum Jumps…”

Clocking Dark Matter…

Topics: Dark Matter, Modern Physics, Quantum Mechanics An optical clock has been used to set new constraints on a proposed theory of dark matter. Researchers including Jun Ye at JILA at the University of Colorado, Boulder, and Andrei Derevianko at the University of Nevada, Reno, explored how the coupling between regular matter and “ultralight” dark matter particles could beContinue reading “Clocking Dark Matter…”
