Query: Testing Chameleons Using Neutron Interferometry   Chameleons are a well motivated scalar field that might explain the observed
late time accelerated expansion of the universe. Chameleons possess the
interesting property that their mass, and hence interaction range, is dependent
on the density of their environment. One very appealing feature of chameleons
is the potential to test a model of dark energy in a laboratory setting. Here
we briefly review two proposed experiments to search for chameleons using
neutron interferometry techniques for the Snowmass 2013 Community Summer Study.
