Solitary Alfven wave envelopes and the modulational instability

Technical Report ·
DOI:https://doi.org/10.2172/6268161· OSTI ID:6268161
The derivative nonlinear Schroedinger equation describes the modulational instability of circularly polarized dispersive Alfven wave envelopes. It also may be used to determine the properties of finite amplitude localized stationary wave envelopes. Such envelope solitons exist only in conditions of modulational stability. This leaves open the question of whether, and if so, how, the modulational instability produces envelope solitons. 12 refs.
