Hartree approximation II: The thermodynamic limit

Domenii publicaţii > Fizica + Tipuri publicaţii > Articol în revistã ştiinţificã

Editorial: J. Math. Phys., 42, p.3407-3423, 2001.

Rezumat:

We investigate the thermodynamic limit of the Hartree approximation for periodic background potentials and short range two-body interactions. We prove that, for any finite volume, the Hartree problem has a unique solution among the periodic densities of particles provided the coupling constant is smaller than a certain value. This value is independent of volume. We also prove that these solutions converge as the thermodynamic limit is considered.
