A Langmuir soliton is a type of solitary wave that occurs in plasmas, characterized by its ability to maintain its shape while traveling at a constant speed. These solitons arise due to the balance between nonlinearity and dispersion, which allows them to propagate without changing form. In plasma physics, Langmuir solitons are significant as they can be associated with electron oscillations and play a crucial role in energy transport within plasma systems.
