Slater determinant

noun

Etymology

Named after John C. Slater, who introduced the determinant in 1929 as a means of ensuring the antisymmetry of a many-electron wavefunction, although the wavefunction in the determinant form first appeared independently in Heisenberg's and Dirac's articles three years earlier.

Definitions

    An expression that describes the wavefunction of a multifermionic system. It satisfies antisymmetry requirements, and consequently the Pauli exclusion principle, by changing sign upon exchange of two electrons (or other fermions).
