A Discrete Variational Approach for Investigation of Stationary Localized States In A Discrete Nonlinear Schrdinger Equation, Named IN-DNLS
K. Kundu
IN-DNLS, considered here is a countable infinite set of coupled one dimensional nonlinear ordinary differential difference equations with a tunable nonlinearity parameter, . Thi…
Stationary localized states due to quadratic nonlinearity in one dimensional systems
Anandamohan Ghosh, B. C. Gupta, K. Kundu
We investigate the effect of a nondegenerate quadratic nonlinear dimeric impurity on the formation of stationary localized states in one dimensional systems. We also consider the f…
Stationary Localized States Due to a Nonlinear Dimeric Impurity Embedded in a Perfect 1-D Chain
B. C. Gupta, K. Kundu
The formation of Stationary Localized states due to a nonlinear dimeric impurity embedded in a perfect 1-d chain is studied here using the appropriate Discrete Nonlinear Schr$\ddot…
A Study of The Formation of Stationary Localized States Due to Nonlinear Impurities Using The Discrete Nonlinear Schrödinger Equation
B. C. Gupta, K. Kundu
The Discrete Nonlinear Schrdinger Equation is used to study the formation of stationary localized states due to a single nonlinear impurity in a Caley tree and a dimeric…
A study of one dimensional correlated disordered systems using invariant measure method
K. Kundu, D. Giri, K. Ray
The behavior of electronic states of one dimensional correlated disordered systems which are modelled by a tight binding Hamiltonian is studied analytically using the invariant mea…
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…
