Long-range scattering for 2D Dirac-Hartree equations

We investigate the long-time behavior of small solutions to the Dirac-Hartree equation in two spatial dimensions. This model describes the mean-field dynamics of relativistic fermions interacting through the three-dimensional Coulomb potential $|x|^{-1}$, which gives rise to long-range effects in the scattering dynamic...

Asymptotic Behavior of One-Dimensional Hartree Equations with the Long-Range Interaction

We investigate the long-time behavior of small solutions to the one-dimensional Hartree equation with the soft Coulomb interaction. The Hartree equation arises as an effective mean-field model for the evolution of many-body quantum systems, while the soft Coulomb potential provides a regularized one-dimensional approxi...
