Exciton-phonon droplets with Bose-Einstein condensate: transport and optical properties
D. Roubtsov, Y. Lepine, I. Loutsenko
We discuss the possibility for a moving droplet of excitons and phonons to form a coherent state inside the packet. We describe such an inhomogeneous state in terms of Bose-Einstei…

Asymmetric shape and dynamic stability of exciton-phonon solitons moving in a periodic medium
D. Roubtsov, Y. Lepine, E. N. Onder
Solitons are known to move ballistically through a medium without changement of their shape. In practice, the shape of moving inhomogeneous states changes, and a long lasting tail…
