Conformal Field Theory

A conformal field theory (CFT) is a quantum field theory also recognized as a statistical mechanics model at the critical point, that is invariant under conformal transformations i.e. transformations that preserve angles but not lengths. Conformal field theory is often studied in two dimensions where there is an infinite-dimensional group of local conformal transformations, described by the holomorphic functions. Conformal field theory has important applications in string theory, statistical mechanics, and condensed matter physics. The theory was first proposed by Leigh Page and Norman I. Adams.

Famous quotes containing the words field and/or theory:

    ... many American Jews have a morbid tendency to exaggerate their handicaps and difficulties. ... There is no doubt that the Jew ... has to be twice as good as the average non- Jew to succeed in many a field of endeavor. But to dwell upon these injustices to the point of self-pity is to weaken the personality unnecessarily. Every human being has handicaps of one sort or another. The brave individual accepts them and by accepting conquers them.
    Agnes E. Meyer (1887–1970)

    Freud was a hero. He descended to the “Underworld” and met there stark terrors. He carried with him his theory as a Medusa’s head which turned these terrors to stone.
    —R.D. (Ronald David)
