Loss induced dynamics of optical pulses in saturable nonlinear media
Golam Ali Sekh
We consider pulse propagation in a saturable nonlinear coupler whose other arm is dissipative and other is transparent. A flow of energy from transparent to dissipative arm takes p…

Quantum droplets in dipolar quasi-one-dimensional Bose-Einstein condensates in optical lattices
Sk Siddik, Golam Ali Sekh
We consider quantum droplets in dipolar Bose-Einstein condensates embedded in optical lattices within the framework of Gross-Pitaevskii equations. In dipolar BECs, the long-range a…

Simulation of single-qubit gates in spin-orbit coupled Bose-Einstein condensate with cubic-quintic nonlinearity by nonlinear perturbations
Prithwish Ghosh, Kajal Krishna Dey, Golam Ali Sekh
We consider spin-orbit coupled Bose-Einstein condensates with cubic-quintic nonlinear interaction within the framework of second quantization formulation and find eigen states usin…
