The nonrelativistic many-electron system in the forward, exchange and BCS approximation is considered. In this approximation, the model is explicitly solvable for arbitrary space dimension d. Theâ€¦ (More)

We prove that the global minimum of the real part of the full effective potential of the many electron system with attractive delta interaction is in fact given by the BCS mean field configuration.â€¦ (More)

For a gaussian interaction V (x, y) = Î» eâˆ’ x2+y2 2r2 with long range r >> lB, lB the magnetic length, we rigorously prove that the eigenvalues of the finite volume Hamiltonian HN,LL = PLLHNPLL, HN =â€¦ (More)

In these lectures, we consider a many-body system that is somewhat unusual in that the Fermi surface survives the turning on of all suuciently weak short range interactions. The system consists of aâ€¦ (More)

Seven cases of crystalluria following primidone overdose have been reported since the 1950s. An eighth case of primidone crystalluria following overdose is presented. Because of low aqueousâ€¦ (More)
