• Calculating the electron's magnetic moment : State-dependent values emerge from Dirac equation

  9 juillet
  Quantum mechanics has a reputation that precedes it. Virtually everyone who has bumped up against the quantum realm, whether in a physics class, in the lab, or in popular science writing, is left thinking something like, "Now, that is really weird." For some, this translates to weird (…)

• Stoichiometric crystal shows promise in quantum memory

  9 juillet
  For over two decades, physicists have been working toward implementing quantum light storage—also known as quantum memory—in various matter systems. These techniques allow for the controlled and reversible mapping of light particles called photons onto long-lived states of matter. But storing (…)

• Scientists provide clear observation of spin and density modes in a two-component fluid of light

  9 juillet
  Recent physics studies have found that light can sometimes flow in unexpected ways, behaving like a so-called "superfluid." Superfluids, such as ultracold atomic gases or helium-4 below specific temperatures, are phases of matter characterized by flowing behavior with zero viscosity (…)

• Measuring individual radioactive decays enables faster detection method for nuclear applications

  8 juillet
  Researchers at the National Institute of Standards and Technology (NIST) have demonstrated a new and faster method for detecting and measuring the radioactivity of minuscule amounts of radioactive material. The innovative technique, known as cryogenic decay energy spectrometry (DES), could have (…)

• Spin as an input parameter : Machine learning predicts magnetic properties of materials

  8 juillet
  Magnetic materials are in high demand. They're essential to the energy storage innovations on which electrification depends and to the robotics systems powering automation. They're also inside more familiar products, from consumer electronics to magnetic resonance imaging (MRI) machines.
