Modulational instability
ID: modulational-instability
Modulational instability is a phenomenon that occurs in nonlinear systems, particularly in the context of wave propagation. It refers to the tendency of a homogeneous wave train (a continuous wave that has a constant amplitude and frequency) to become unstable and develop spatial or temporal variations in amplitude, leading to the formation of localized structures, such as solitons or rogue waves. This instability arises in various fields, including fluid dynamics, nonlinear optics, plasma physics, and condensed matter physics.
