چکیده

We present in this document some essential properties of solutions to the homogeneous Landau-Fermi-Dirac equation for moderately soft potentials. Uniform time estimates statistical moments, $L^{p}$-norm generation and Sobolev regularity are shown using a combination techniques that include recent developments concerning level set analysis spirit De Giorgi refined entropy-entropy dissipation functional inequalities Landau collision operator which extended case question here. As consequence analysis, we prove algebraic relaxation non degenerate distributions towards Fermi-Dirac statistics under weak saturation condition initial datum. All quantitative uniform with respect quantum parameter. They therefore also hold classical limit, is equation.

Supersymmetric structure in the Dirac equation with cylindrically-deformed potentials

The Dirac equation plays a key role in microscopic descriptions of many-fermion systems, employing covariant density functional theory and the relativistic mean-field approach. In application to nuclei and hadrons, the required Dirac mean-field Hamiltonian involves a mixture of Lorentz vector and scalar potentials. Recently, symmetries of Dirac Hamiltonians with such Lorentz structure were show...

[hal-00289384, v1] Well-posedness of the spatially homogeneous Landau equation for soft potentials

Abstract. We consider the spatially homogeneous Landau equation of kinetic theory, and provide a differential inequality for the Wasserstein distance with quadratic cost between two solutions. We deduce some well-posedness results. The main difficulty is that this equation presents a singularity for small relative velocities. Our uniqueness result is the first one in the important case of soft ...

Fermi-Dirac-Fokker-Planck Equation: Well-posedness & Long-time Asymptotics

A Fokker-Planck type equation for interacting particles with exclusion principle is analysed. The nonlinear drift gives rise to mathematical difficulties in controlling moments of the distribution function. Assuming enough initial moments are finite, we can show the global existence of weak solutions for this problem. The natural associated entropy of the equation is the main tool to derive uni...

A Z-dependent variational solution of Thomas-Fermi-Dirac equation

Using Thomas-Fermi-Dirac equation within the exchange-correlation scheme and a Z-dependent trial solution, the ground state binding energy for neutral, positively, and negatively charged atoms are calculated. Comparing to the results obtained in earlier works, the values of the binding energy estimated here for both light and heavy atoms agree nicely with the Hartree-Fock values. We have also c...
