Embedded soliton solutions : A variational study
Debabrata Pal, Sk. Golam Ali, B. Talukdar
We use a variational method to construct soliton solutions for systems characterized by opposing dispersion and competing nonlinearities at fundamental and second harmonics. We sho…
Matter-wave bright solitons of Li gas in an expulsive potential
Sk. Golam Ali, B. Talukdar
A Lagrangian based method is used to derive an analytical model for studying the dynamics of matter-wave bright soliton created in a harmonic potential which is attractive in the t…
Bright solitons in asymmetrically trapped Bose-Einstein condensate
Sk. Golam Ali, B. Talukdar, S. K. Roy
We study the dynamics of bright solitons in a Bose-Einstein condensate (BEC) confined in a highly asymmetric trap. While working within the f ramework of a variational approach we…
Inverse problem of variational calculus for nonlinear evolution equations
Sk. Golam Ali, B. Talukdar, U. Das
We couple a nonlinear evolution equation with an associated one and derive the action principle. This allows us to write the Lagrangian density of the system in terms of the origin…
