Dark energy via multi-Higgs doublet models: accelerated expansion of the
  Universe in inert doublet model scenario
  Scalar fields are among the possible candidates for dark energy. This paper
is devoted to the scalar fields from the inert doublet model, where instead of
one as in the standard model, two SU(2) Higgs doublets are used. The component
fields of one SU(2) doublet ($\phi_1$) act in an identical way to the standard
model Higgs while the component fields of the second SU(2) doublet ($\phi_2$)
are taken to be the dark energy candidate (which is done by assuming that the
phase transition in the field has not yet occurred). It is found that one can
arrange for late time acceleration (dark energy) by using an SU(2) Higgs
doublet in the inert Higgs doublet model, whose vacuum expectation value is
zero, in the quintessential regime.
