different between fermion vs fermium

English

Etymology

From Fermi +? -on, after Italian-American physicist Enrico Fermi. Coined by English physicist Paul Dirac in 1945 in a lecture titled "Developments in Atomic Theory".

Pronunciation

• IPA^(key): /?f??m??n/

Noun

fermion (plural fermions)

1. (particle physics, Standard Model) Any elementary or composite particle that has half-integer spin and thus obeys Fermi–Dirac statistics and the Pauli exclusion principle (equivalently, a particle for which the wavefunction of any system of identical such particles changes sign whenever two are swapped); a baryon, a lepton or a quark;
   (slightly more loosely) any such particle or any composite particle composed of fermions.
   • 1994, István Montvay, Gernot Münster, Quantum Fields on a Lattice, Cambridge University Press, page 208,

     A remarkable feature of lattice regularization is the appearance of several fermion species per fermion field in the lattice action.

   • 1996, Georges Bouzerar, Didier Poilblanc, Persistent Currents in Interacting Electronic Systems, T. Martin, G. Montambaux, J. Trân Thanh Vân (editors), Correlated Fermions and Transport in Mesoscopic Systems, Editions Frontieres, page 149,

     For 2D systems, going beyond first order pertu[r]bative calculations, we show that the second harmonic of the current is strongly suppressed in the case of spinless fermion models but significantly enhanced for the Hubbard model.

   • 1996, Georg G. Raffelt, Stars as Laboratories for Fundamental Physics, University of Chicago Press, page 253,

     It is not known whether the Higgs mechanism is the true source for the masses of the fundamental fermions.
