Research in modern gravitational physics tries to unify both the guiding principles of physics and all fundamental interactions in a consistent framework. Our project is therefore aimed at studying in detail gravitation and the physics of the Universe within the framework of field theory, while paying attention to experimental verifications, which are essential to put the theoretical models on firm ground. The principles of quantum physics at the Planck scale might have driven the quantum birth of the Universe and its evolution into the currently observed classical Universe. Thus, the following key open problems in gravitational physics will be investigated:

  • Quantum gravity and quantum cosmology based on functional integrals or nonperturbative methods. Possible signatures of quantum gravity effects in the cosmic microwave background and in experiments on earth. Cosmological singularities in quantum gravity. Impact of geodesic and frame-dragging precession measurement on theories of quantum gravity.
  • Why is the universe undergoing accelerated expansion? What is the 96% of the Universe made of? Is it necessary to modify the gravitational Lagrangian and the theory of matter fields coupled to gravity? Dark energy and relativistic theories of gravity; f(R) and scalar-tensor theories of gravity; interplay with inflationary models. Effects of f(R) theories on the matter-antimatter asymmetry./li>
  • Dark matter problem and gravitational lensing; realistic models of gravitational lenses; structure formation in the universe; cosmic defect theory.


Since October 2001, we have initiated a series of annual workshops, devoted to an informal presentation of our research, with a discussion of results and open problems. We have also contributed to the organization of the Conferences:
