【 摘 要 】

We study solitonic excitations in two kinds of samples in the fractional quantum Hall effect regime. One is a strip modulated by a one-dimensional array of gates; the other is constructed of two parallel strips coupled by a one-dimensional array of tunnel barriers. We predict the existence of integer charge solitons in the first case and fractional charge solitons in the second case. We study the two cases in both the dissipative and the inertial limits.
