Abstract
Compressive square-wave pulses are launched in a double-plasma device. Their evolution is interpreted according to the Korteweg—de Vries description of Washimi and Taniuti. Square-wave pulses are an excitation for which an explicit solution of the Schrödinger equation permits an analytical prediction of the number and amplitude of emergent solitons. Bursts of energetic particles (pseudowaves) appear above excitation voltages greater than an electron thermal energy, and may be mistaken for solitons.Keywords
