Description
Group field theories are a class of models that are
designed to define a sum over histories approach to
quantum gravity. After a brief presentation of the
relevant
points and features of the theory, I will describe a
preliminary attempt to give an effective description of
homogeneous cosmologies and their effective dynamics,
within an approximation of the full group field theory
dynamics that matches closely the Bogoliubov
approximation to the dynamics of Bose-Einstein
condensates.
