Spinors and Scalars in curved spacetime: neutrino dark energy
  (DE$_{\nu}$)
  We study the interaction, in general curved spacetime, between a spinor and a
scalar field describing dark energy; the so-called DE$_{\nu}$ model in curved
space. The dominant term is the dimension 5 operator, which results in
different energy shifts for the neutrino states: an Aharonov-Bohm-like effect.
We study the phenomenology of this term and make observational predictions to
detect dark energy interactions in the laboratory due to its effect on neutrino
oscillation experiments, which opens up the possibility of designing
underground experiments to detect dark energy. This dimension 5 operator beyond
the Standard Model interaction is less suppressed than the widely discussed
dimension 6 operator, which corresponds to mass varying neutrinos; the
dimension 5 operator does not suffer from gravitational instabilities.
