Query: Relational evolution of effectively interacting GFT quantum gravity
  condensates   We study the impact of effective interactions onto relationally evolving GFT
condensates based on real-valued fields. In a first step we show that a free
condensate configuration in an isotropic restriction settles dynamically into a
low-spin configuration of the quantum geometry. This goes hand in hand with the
accelerated and exponential expansion of its volume, as well as the vanishing
of its relative uncertainty which suggests the classicalization of the quantum
geometry. The dynamics of the emergent space can then be given in terms of the
classical Friedmann equations. In contrast to models based on complex-valued
fields, solutions avoiding the singularity problem can only be found if the
initial conditions are appropriately chosen. We then turn to the analysis of
the influence of effective interactions on the dynamics by studying in
particular the Thomas-Fermi regime. In this context, at the cost of
fine-tuning, an epoch of inflationary expansion of quantum geometric origin can
be implemented. Finally, and for the first time, we study anisotropic GFT
condensate configurations and show that such systems tend to isotropize quickly
as the value of the relational clock grows. This paves the way to a more
systematic investigation of anisotropies in the context of GFT condensate
cosmology.
