Query: Radiative neutrino mass generation and dark energy   We study the models with radiative neutrino mass generation and explore the
relation between the neutrino masses and dark energy. In these models, the
pseudo-Nambu-Goldston bosons (pNGBs) arise at two-loop level via the Majorana
neutrino masses. In particular, we demonstrate that the potential energy of the
pNGB can be the dark energy potential and the observed value of the equation of
state (EoS) parameter of the universe, $i.e.$, $w\simeq -1$, can be realized.
