Pablo Rodriguez-Lopez
Quantum friction with Unruh-deWitt detectors
Lieu : Amphithéâtre, maison des Magistères,
le vendredi 21 septembre 2018 à 11h00
Personne à contacter : Serge Florens ()

We revisit the atom-plate quantum friction and Casimir force with a full-relativistic formalism for atoms modelled as Unruh-deWitt detectors [1] in exited, relaxed and coherent superposition close to a plate [2]. We show that, for relative velocities close to c, the quantum friction diverges while the Casimir force is almost independent of the velocity. We are able to include the effect of the finite size of the detector, then we also obtain quantum friction when the detector is isolated but follows a non-inertial trajectory and we obtain a more realistic result for short distance interactions. Those studies open the venue to understand the role of non-local response in quantum friction. [1] E. Martin-Martinez and P. Rodriguez-Lopez.
