Coherent interaction between two exciton-phonon solitons due to Bose-Einstein condensation

Abstract : Nonlinear interaction between two soliton pulses consisting of exciton-phonon coherent fields is observed after propagation in Cu2O. Each soliton is formed independently by random photocreation of hot excitons followed by rapid cooling and Bose-Einstein condensation. The positive interference appears with a delay attributed to the build-up of a common phase for the wavefunctions.
