Anomaly - Physics

Physics

  • Anomaly (physics), a failure of a symmetry of a theory's classical action
  • Conformal anomaly, a quantum phenomenon that breaks the conformal symmetry of the classical theory
  • Chiral anomaly, an anomalous nonconservation of a chiral current
  • Gauge anomaly, the effect of quantum mechanics that invalidates the gauge symmetry of a quantum field theory
  • Global anomaly, an anomaly in quantum physics
  • Gravitational anomaly, an effect in quantum mechanics that invalidates the general covariance of some theories of general relativity
  • Mixed anomaly, an effect in quantum mechanics
  • Parity anomaly, an anomaly that is associated with parity
  • Konishi anomaly, the violation of the conservation of the Noether current associated with certain transformations
  • Anomalons, some odd particle interactions that are seen in some high-energy physics
  • Anomalous skin effect, when electromagnetic fields penetrate into a metal by an amount comparable to, or much less than, the mean free path. Brian Pippard used it to determine the Fermi surface of copper.
  • Anomalous dispersion (optics), when the speed of an electromagnetic wave increases with increasing frequency

Famous quotes containing the word physics:

    The fundamental laws of physics do not describe true facts about reality. Rendered as descriptions of facts, they are false; amended to be true, they lose their explanatory force.
    Nancy Cartwright (b. 1945)

    Now the twitching stops. Now you are still. We are through with physiology and theology, physics begins.
    Alfred Döblin (1878–1957)
