Bound-state momentum-space wave function of the quasi-one-dimensional hydrogen atom
Aparna Saha, Benoy Talukdar, Supriya Chatterjee
We prove that the bound-state momentum-space wave function for the quasi-one-dimensional hydrogen atom as used by Olendski in two recent publications (Eur. J. Phys.38, 03800…
On the correlation measure of two-electron systems
Aparna Saha, B. Talukdar, Supriya Chatterjee
We make use of a Hylleraas-type wave function to derive an exact analytical model to quantify correlation in two-electron atomic/ionic systems and subsequently employ it to examine…
Fisher information for quasi-one-dimensional hydrogen atom
Aparna Saha, Benoy Talukdar, Supriya Chatterjee
The coordinate-space wave function of quasi-one-dimensional atoms is defined in the region only. This poses a typical problem to write a physically acceptable mome…
Remarks on the first integral method for solving nonlinear evolution equations
Aparna Saha, B. Talukdar Umapada Das, Supriya Chatterjee
We point out that use of the first integral method ( J.Phys. A :Math. Gen. 35 (2002) 343 ) for solving nonlinear evolution equations gives only particular solutions of equations th…
Solitons, compactons and undular bores in Benjamin-Bona-Mahony-like systems
Aparna Saha, B. Talukdar, Umapada Das +1
We examine the effect of dissipation on traveling waves in nonlinear dispersive systems modeled by Benjamin- Bona- Mahony (BBM)-like equations. In the absence of dissipation the BB…
