  1. Há 2 dias · This phenomena centers around Weyl fermions - elusive particles predicted by Hermann Weyl in the early 20th century. Found within certain magnetic materials, these fermions are stirring excitement due to their unusual transport properties. The spotlight of such studies currently shines on the chiral antiferromagnets Mn3Sn and Mn3Ge.

  2. Há 1 dia · As noted above, Dirac initially thought that the hole might be the proton, but Hermann Weyl pointed out that the hole should behave as if it had the same mass as an electron, whereas the proton is over 1800 times heavier.

  3. Há 9 horas · The energetics in a molecular simulation rely upon the electrons and atomic nuclei in a structure. Hermann Weyl related the energetics of electrons to their temporal mode: “All the physical characteristics of the ultimate elementary particles of matter, particularly of electrons, can be read off from the neighboring field. …

  4. Há 9 horas · Early life Childhood and education Oppenheimer was born Julius Robert Oppenheimer into a non-observant Jewish family in New York City on April 22, 1904, to Ella (née Friedman), a painter, and Julius Seligmann Oppenheimer, a successful textile importer. Robert had a younger brother, Frank, who also became a physicist. Their father was born in Hanau, when it was still part of the Hesse-Nassau ...

  5. Há 5 dias · Polar metals are challenging to identify spectroscopically because the fingerprints of electric polarization are often obscured by the presence of screening charges. Here, we unravel unambiguous signatures of a distortive polar order buried in the Fermi sea by probing the nonlinear optical response of materials driven by tailored terahertz fields.

  6. Há 5 dias · Albert Einstein. After graduation in 1900, Einstein faced one of the greatest crises in his life. Because he studied advanced subjects on his own, he often cut classes; this earned him the animosity of some professors, especially Heinrich Weber. Unfortunately, Einstein asked Weber for a letter of recommendation.

  7. Há 4 dias · Herman Melville (born Melvill; August 1, 1819 – September 28, 1891) was an American novelist, short story writer, and poet of the American Renaissance period. Among his best-known works are Moby-Dick (1851); Typee (1846), a romanticized account of his experiences in Polynesia; and Billy Budd, Sailor, a posthumously published novella.
