Phase Space Analysis and Soliton Solution for Quartic Potential

Muzzammil Ahmad Bhat, N. K. Pandey, Shiekh Abid Hussain

Abstract: We study dynamics of solitons under the rotating wave approximation by considering a weak quartic nearest neighbour interparticle interaction potential. Also we discussed qualitative analysis of dynamical system in the phase plane where localised solutions correspond to a separatrix curve.
