Encyclopedia

Particle is a small localized object to which can be ascribed several physical or chemical properties such as volume, density or mass. They vary greatly in size or quantity, from subatomic particles like the electron, to microscopic particles like atoms and molecules, to macroscopic particles like powders and other granular materials. Particles can also be used to create scientific models of even larger objects depending on their density, such as humans moving in a crowd or celestial bodies in motion. — Wikipedia

Science

Particle physics (also high energy physics) is the branch of physics that studies the nature of the particles that constitute matter and radiation. Although the word particle can refer to various types of very small objects (e.g. protons, gas particles, or even household dust), particle physics usually investigates the irreducibly smallest detectable particles and the fundamental interactions necessary to explain their behavior. By our current understanding, these elementary particles are excitations of the quantum fields that also govern their interactions. The currently dominant theory explaining these fundamental particles and fields, along with their dynamics, is called the Standard Model. — Wikipedia

    on July 23, 2021 at 2:39 pm

    In a new publication from Opto-Electronic Advances, researchers led by Professor Liu Yan from Xidian University, China and Professor Gan Xuetao from Northwestern Polytechnical University, China, consider generation and application of the high-Q resonance in all-dielectric metasurfaces.

    Behold the neutron, the middle child of subatomic particles. At times overshadowed by its electrically charged siblings the proton and the electron, neutrons quietly play important roles in national security. They start nuclear reactions for weapons and power plants. They bombard materials for nuclear safety tests. And now they have a new skill: telling whether a concealed, electric detonator is charged.

    on July 22, 2021 at 6:57 am

    A team of scientists at Los Alamos National Laboratory propose that modulated quantum metasurfaces can control all properties of photonic qubits, a breakthrough that could impact the fields of quantum information, communications, sensing and imaging, as well as energy and momentum harvesting. The results of their study were released yesterday in the journal Physical Review Letters, published by the American Physical Society.

    As the Summer Olympics draw near, the world will shift its focus to photo finishes and races determined by mere fractions of a second. Obtaining such split-second measurements relies on faultlessly rounding a raw time recorded by a stopwatch or electronic timing system to a submitted time.

    on July 21, 2021 at 3:00 pm

    Researchers have discovered a "layer" Hall effect in a solid state chip constructed of antiferromagnetic manganese bismuth telluride, a finding that signals a much sought-after topological Axion insulating state, the team reports in the current edition of the journal Nature.

  • Antimatter from laser pincers
    on July 22, 2021 at 3:30 pm

    An international physics team has proposed a new concept that may allow selected cosmic extreme processes to be studied in the laboratory in the future. A special setup of two high-intensity laser beams could create conditions similar to those found near neutron stars, for example. An antimatter jet is generated and accelerated very efficiently, as the experts report.

    on July 21, 2021 at 6:19 pm

    Physicists have observed signs of a rare type of superconductivity in a material called 'magic-angle' twisted trilayer graphene. They report that the material exhibits superconductivity at surprisingly high magnetic fields of up to 10 Tesla, which is three times higher than what the material is predicted to endure if it were a conventional superconductor.

    on July 21, 2021 at 2:22 pm

    A so-called 'strange metal', well-known for its unusual properties, has been shown to be a superconductor at very low temperatures. This allows scientists to study the connection between 'strange metal'-behavior and superconductivity, which could be an important step towards understanding the phenomenon of high-temperature superconductivity.

  • Ultrathin magnet operates at room temperature
    on July 20, 2021 at 3:43 pm

    Scientists have created an ultrathin magnet that operates at room temperature. The ultrathin magnet could lead to new applications in computing and electronics -- such as high-density, compact spintronic memory devices -- and new tools for the study of quantum physics.
