Fock representation
WebRepresentation theory is a branch of mathematics that studies abstract algebraic structures by representing their elements as linear transformations of vector spaces, and studies modules over these abstract algebraic structures. [1] [2] In essence, a representation makes an abstract algebraic object more concrete by describing its … WebVladimir Aleksandrovich Fock (or Fok; Russian: Влади́мир Алекса́ндрович Фок) (December 22, 1898 – December 27, 1974) was a Soviet physicist, who did foundational work on quantum mechanics and quantum electrodynamics. Biography [ edit] He was born in St. Petersburg, Russia.

WebJul 22, 2024 · The Fock operator is a one-electron operator and solving a Hartree-Fock equation gives the energy and Hartree-Fock orbital for one electron. For a system with 2N electrons, the variable i will range from 1 to N; i.e there will be one equation for each orbital. The reason for this is that only the spatial wavefunctions are used in Equation 9.7.1. WebSep 22, 2024 · In the Fock basis, this can be decomposed as. (A) α = e − α 2 / 2 e α a † 0 = e − α 2 / 2 ∑ k = 0 ∞ α k k! k . An alternative way to express a coherent state is via its wavefunction in the position representation, denote it with ψ α ( x) (it's worth stressing that here "position" is to be understood as an abstract ...
