Hartree-Fock Approximation and Entanglement

The relation between the correlation energy and the entanglement is analytically constructed for the Moshinsky’s model of two coupled harmonic oscillators. It turns out that the two quantities are far to be proportional, even at very small couplings. A comparison is made also with the 2-point Ising model.

The quantum discrete self-trapping equation in the Hartree approximation

We show how the Hartree approximation (HA) can be used to study the quantum discrete self-trapping (QDST) equation, which in turn provides a model for the quantum description of several interesting nonlinear effects such as energy localization, soliton interactions, and chaos. The accuracy of the Hartree approximation is evaluated by comparing results with exact quantum mechanical calculations ...

Finite Temperature Effective Potential in the Hartree-fock Approximation

In order to investigate the nature of the phase transition, we study the finite temperature effective potential for the λΦ theory in the Hartree-Fock approximation, which sums up all the daisy and superdaisy diagrams.

Resonant continuum in the Hartree-Fock+BCS approximation

A method for incorporating the effect of the resonant continuum into Hartree-Fock+BCS equations is proposed. The method is applied for the case of a neutron-rich nucleus calculated with a Skyrme-type force plus a zero-range pairing interaction and the results are compared with HartreeFock-Bogoliubov calculations. It is shown that the widths of resonant states have an important effect on the pai...

Neutron Stars and Nuclei in the Modified Relativistic Hartree Approximation

We have examined the properties of neutron-rich matter and finite nuclei in the modified relativistic Hartree approximation for several values of the renormalization scale, μ, around the standard choice of μ equal to the nucleon mass M . Observed neutron star masses do not effectively constrain the value of μ. However for finite nuclei the value μ/M=0.79, suggested by nuclear matter data, provi...
