Graphullerene…

Credit: Nicoletta Barolini Topics: Chemistry, Graphene, Materials Science, Modern Physics, Nanotechnology Graphullerene, an atom-thin material made of linked fullerene subunits, gives scientists a new form of modular carbon to play with. Carbon, in its myriad forms, has long captivated the scientific community. Besides being the primary component of all organic life on earth, material formsContinue reading “Graphullerene…”

Quipu…

Topics: Lasers, Modern Physics, Quantum Computer, Quantum Mechanics Physicists have devised a mind-bending error-correction technique that could dramatically boost the performance of quantum computers. When the ancient Incas wanted to archive tax and census records, they used a device made up of a number of strings called a quipu, which encoded the data in knots. Fast-forwardContinue reading “Quipu…”

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…”

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…”
