Gravitation
Gravitational problems constitute for the theoretical physics team a cross-disciplinary field of application of the theoretical and numerical tools developed in the group's two other themes ( dynamical systems and quantum information ). We are interested in both classical gravity and quantum gravity theories.
Our main study topics are:
- Astronomical dynamical systems (solar system, asteroids, comets, binary stars)
- Dark matter in the solar system (capture mechanism, distribution, possible low energy experiments)
- Black holes and wormholes (geometry, information paradox, quantization, chaotic horizons, traces in gravitational wave signals)
- Quantum gravity models (brane worlds, matrix models in string theory, noncommutative geometry, LQG)
