Abstract
The zero temperature Hall constant RH, described by reactive (nondissipative) conductivities, is analyzed within linear response theory. It is found that in a certain limit, RH is directly related to the density dependence of the Drude weight implying a simple picture for the change of sign of charge carriers in the vicinity of a Mott-Hubbard transition. This novel formulation is applied to the calculation of RH in quasi-one dimensional and ladder prototype interacting electron systems.
