In quantum spin systems, lower energy state for a nuclear spin in an external field is spin (+
1/2) while the higher energy state is spin (-1/2). A continuum analog to the discrete model …

We study the dynamics of optical soliton in birefringent optical fiber with the effect of inter-
modal dispersion. We consider the model of the Kundu-Eckhaus (KE) equation for …

We study the impact of modified saturable nonlinearity on modulational instability (MI)
criteria in a coupled birefringent fiber using pulse propagation technique. Based on the …

This paper intends to present an investigation of the ultra shortpulse propagation under the
nonlinear birefringent Kundu-Eckhaus (KE) model. The dynamics of modulational instability …

The analytical study on the 1D frustrated ferromagnetic spin chain with added biquadratic

Abstract The one-dimensional (1D) Heisenberg spin chain system (HSCS) allows to
investigate anomalous features originating from strong quantum fluctuations, which become …
