Derivation of Generalized von Weizsäcker Kinetic Energies from Quasiprobability Distribution Functions

  • Chapter
Statistical Complexity

Abstract

The Fisher Information of the electronic distribution functions is closely related to the von Weizsäcker kinetic energy functional. We show how generalizations of the Weizsäcker kinetic energy density functional can be derived from the canonical momentum-space expression for the kinetic energy and extend this result to higher-order electron distribution functions.
