Guillaume Pignol is associate professor at Grenoble university since 2010.
His research is focussed on precision experiments using neutrons to test fundamental interactions and symmetries. He contributes to two major projects, both using ultracold neutrons as a very sentisitive probe. The first one is the GRANIT project, aiming at measuring the quantum behaviour of bouncing neutrons, to verify Einstein's equivalence principle in a quantum context. This experiment takes place at the high flux reactor of the Institut Laue Langevin in Grenoble. The second one is an apparatus using ultracold neutrons produced at the Paul Scherrer Institut, dedicated to the measurement of the electric dipole moment of the neutron.
The goal of this experiment is to test the time-reversal symmetry at the subatomic level.
