  The effective vacuum energy density contributed by the non-trivial contortion
distribution and the bare vacuum energy density can be viewed as the energy
density of the auxiliary quintessence field potential. We find that the
negative bare vacuum energy density from string landscape leads to a
monotonically decreasing quintessence potential while the positive one from
swampland leads to the meta stable or stable de Sitter like potential.
Moreover, the non-trivial Brans-Dicke like coupling between quintessence field
and gravitation field is necessary in the latter case.
