Electrostatic acoustic modes in a self-gravitating complex plasma with variable charge impurities
Amar P Misra, K. Roy Chowdhury, A. Roy Chowdhury
A linear theory of dust acoustic (DA) and dust ion-acoustic (DIA) waves in a self-gravitating collisional dusty plasma contaminated by variable-charge impurities is presented for a…
Multiple Attractor in Newton -Leipnik System, Peak to Peak dynamics and Chaos Control
Biswambhar Rakshit, Papri Saha, A. Roy Chowdhury
The chaotic properties of Newton-Leipnik system are discussed from the view point of strange attractors. Previously, two strange attractors of this system were illustrated which oc…
Solitary Optical pulse propagation in fused fibre coupler, Effect of Raman Scattering and switching
Basanti Mondal, A. Roy. Chowdhury
We analyse the motion of solitary type optical pulse in a fused optical fibre coupler when inter channel raman scattering (IRS) is taken into account and same type of dispersion ma…
Moment method, Higher order dispersion map and other effects in optical pulse propagation
Basanti Mondal, A. Roy. Chowdhury
Analytical and numerical procedures are applied to show that both third and second order dispersion maps can be explicitly constructed and their mutual effects on the optical pulse…
Chaos and Control in Nonlinear Bloch System
B. Rakshit, P. Saha, A. Roy. Chowdhury
The dynamics of two nonlinear Bloch systems is studied from the viewpoint of bifur- cation and a particular parameter space has been explored for the stability analysis based on st…
