| Abstract: | Cnoidal wave solutions in the quantum lattice gas model in the presence of the Aharonov_Bohm flux in a ring are found. The energy gap, the effective mass and the bind energy of cnoidal waves are given. It is pointed out that the spin_wave_like and the soliton are the special cases of the cnoidal wave. The effects of the Aharonov_Bohm flux on the soliton is considered. It is shown that the width, the peak, the bind energy and the effective mass of the soliton and the energy gap are affected and a Josephson_like current is induced by the Aharonov_Bohm flux. |
