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…
On Bose-Einstein condensate inside moving exciton-phonon droplets
D. Roubtsov, Y. Lepine, I. Loutsenko
We explore a nonlinear field model to describe the interplay between the ability of excitons to be Bose condensed and their interaction with other modes of a crystal. We apply our…
Bosons in a Lattice: Exciton-Phonon Condensate in Cu2O
D. Roubtsov, Y. Lepine
We explore a nonlinear field model to describe the interplay between the ability of excitons to be Bose-condensed and their interaction with other modes of a crystal. We apply our…
Moving Stationary State of Exciton-Phonon Condensate in Cu2O
D. Roubtsov, Y. Lepine
We explore a simple theoretical model to describe the properties of Bose condensed para-excitons in Cu2O. Taking into account the exciton-phonon interaction and introducing a coher…
On Reduction of Critical Velocity in a Model of Superfluid Bose-gas with Boundary Interactions
D. Roubtsov, Y. Lepine
The existence of superfluidity in a 3D Bose-gas can depend on boundary interactions with channel walls. We study a simple model where the dilute moving Bose-gas interacts with the…
