The effect of discrete-time evolution on thermalisation in a lattice
Thomas Moorcroft, Alberto Amo, François Copie +3
Particles subject to weak contact interactions in a finite-size lattice tend to thermalise. The Hamiltonian evolution ensures energy conservation and the final temperature is fully…

Experimental observation of the spatio-temporal dynamics of breather gases in a recirculating fiber loop
François Copie, Gino Biondini, Jeffrey Oregero +3
We report the first experimental observation of breather gases (BGs) in optics, realized in a recirculating fiber loop enabling virtually lossless propagation over km. Initi…

Controlled manipulation of solitons in a recirculating fiber loop using external potentials
François Copie, Pierre Suret, Stéphane Randoux
Optical solitons are self-sustained wave packets that propagate without distortion due to a balance between dispersion and nonlinearity. Their unique stability underpins key photon…
