Transmission and reflection in a perfectly amplifying and absorbing medium
P. K. Datta
We study transmission and reflection properties of a perfectly amplifying as well as absorbing medium analytically by using the tight binding equation. Different expressions for tr…

Effect of nonlinearity on the dynamics of a particle in dc field-induced systems
P. K. Datta, A. M. Jayannavar
Dynamics of a particle in a perfect chain with one nonlinear impurity and in a perfect nonlinear chain under the action of dc field is studied numerically. The nonlinearity appears…

Time evolution of models described by one-dimensional discrete nonlinear Schrödinger equation
P. K. Datta, K. Kundu
The dynamics of models described by a one-dimensional discrete nonlinear Schrödinger equation is studied. The nonlinearity in these models appears due to the coupling of the electr…
