[00:00:00]Here we have the non-linear Schrödinger equation, one of the fundamental models in the theory of non-linear waves.

[00:00:07]Notice how dispersion tends to spread the wave packet out, while the cubic non-linearity, acting in opposition, works to localize it.

[00:00:16]The balance between these competing effects leads to the formation of soliton-like structures.

[00:00:22]As the initial profile evolves under a periodic external perturbation, we can clearly observe the resulting interference.

[00:00:30]This causes a continuous redistribution of amplitude and ultimately the complex evolution of the wave envelope.
