In this paper we discuss in detail the nonlinear equations of the mean–field approximation and their connection to the exact many–body Schrödinger equation. Then we analyze the mean–field approach and the nonlinear dynamics of a trapped condensate of weakly–interacting bosons.

I discuss three issues relevant to solar neutrino flux measurements: cross section uncertainties in pp chain reactions, uncertainties in the GALLEX/SAGE response to 7 Be and 51 Cr neutrinos, and the implications of helioseismology for nonstandard suns with mixed cores. A few comments are also offered on νe ↔ ντ oscillations, cosmologically interesting neutrino masses, and recent proposals for s...

Through the triple–alpha process practically all of the carbon in our universe is synthesized as the ash of helium burning in red giants. The triple–alpha process proceeds trough the ground state of Be and though the 02+–state in C. We investigate the dependence of 02+–state and the production of carbon as a function of the strength of the underlying nucleon–nucleon interaction. This is perform...

The deuteron axial current is sensitive both to the form of the implementation of relativistic dynamics as well as to the details of the deuteron D state at moderate momentum transfer, making it a natural partner to the magnetic form factor for exploring details of nucleon-nucleon dynamics and associated electroweak properties.
