The DYSCO Team at PhLAM Highlighted in Physical Review Letters!

Their article, entitled “Perturbed Nonlinear Evolution of Optical Soliton Gases: Growth and Decay in Integrable Turbulence”, was selected as an “Editor’s Suggestion” in Physical Review Letters.

This distinction, awarded to a limited selection of particularly outstanding publications, highlights the quality and significance of their research, opening new perspectives on the nonlinear dynamics and integrable turbulence of optical soliton gases.

Congratulations to the entire DYSCO team for this well-deserved international recognition, which once again showcases the scientific excellence of PhLAM.

Abstract : 

We present optical fiber experiments investigating the perturbed, nonintegrable evolution of soliton gases (SGs) under weak linear damping and gain. By measuring the amplitude and phase of the optical field in a recirculating loop, we determine the spectral distribution of SGs at various propagation distances. We demonstrate that a SG, initially prepared as a soliton condensate with a Weyl distribution, undergoes significant changes in its spectral distribution due to dissipation. Specifically, weak gain leads to the emergence of a bichromatic SG, while weak damping results in a SG with a semicircular spectral distribution at long propagation distances. These observed dissipation-driven changes in the SG’s spectral characteristics are not explained by existing hydrodynamic or kinetic theories.
