WebMay 29, 2024 · Abstract. We study linear operators acting on Fock spaces F^p_\alpha for 0 WebAt a local minimum, hmi = 0; this is the Hartree-Fock condition, and E0 is the Hartree-Fock energy. The quadratic terms can be treated as a harmonic oscillator: one treats the zmi as boson operators and using a Bogoliubov trans-formation put into diagonal form, using the famous RPA matrix equation: A B −B∗ −A∗ X~ λ Y~ λ

The eigenvector form (3.2) of these equations is due to Dirac (I930). Equations (3.1) or (3-2) are the Hartree-Fock equations for a single detor. Hartree's equations
WebIn this paper, we investigate the fractional-order Klein–Fock–Gordon equations on quantum dynamics using a new iterative method and residual power series method based on the Caputo operator. The fractional-order Klein–Fock–Gordon equation is a generalization of the traditional Klein–Fock–Gordon equation that allows for non-integer orders of …
