摘要
We study a mixed-state Schrodinger-Poisson-Slater system (SPSS). This system combines the nonlinear and nonlocal Coulomb interaction with a local potential nonlineaxity known as the "Slater exchange term" which models a fermionic effect. The origin of the model is explained and related models are also proposed. Existence, uniqueness and regularity of local-in-time and global solutions axe analyzed in R-3 with L-2 or H-1 initial data. Stationary solutions and conservation laws are also analyzed by using a variational approach due to E. Lieb.
