Objective of the journal: the Comptes rendus Physique are open to all scientists, whatever their title or nationality. An article published 
in the Comptes rendus is the first report of an important discovery or a significant result. It benefits from a fast publication schedule 
once it has been definitively accepted, which makes it possible to establish priority.
