Abstract: | We present a fermion model that is, as we suggest, a natural 2D analogue of the Luttinger model. We derive this model as a
partial continuum limit of a 2D spinless lattice fermion system with local interactions and away from half filling. In this
derivation, we use certain approximations that we motivate by physical arguments. We also present mathematical results that
allow an exact treatment of parts of the degrees of freedom of this model by bosonization, and we propose to treat the remaining
degrees of freedom by mean field theory. |
