Rogue wavefunctions due to noisy quantum tunneling potentials
(Işık University Press, 2017-02-02)
In this paper, we study the effects of white-noised potentials on nonlinear quantum tunneling. We use a split-step scheme to numerically solve the nonlinear Schrodinger equation (NLSE) with a tunneling potential. We consider ...
Amplitude modulation of nonlinear waves in fluid-filled tapered tubes
(Consultants Bureau, 2003-12)
We study the modulation of nonlinear waves in fluid-filled prestressed tapered tubes. For this, we obtain the nonlinear dynamical equations of motion of a prestressed tapered tube filled with an incompressible inviscid ...
Two remarks on a generalized Davey-Stewartson system
(Elsevier Ltd, 2006-03-01)
We present two results on a generalized Davey-Stewartson system, both following from the pseudo-conformal invariance of its solutions. In the hyperbolic-elliptic-elliptic case, under some conditions on the physical parameters, ...
Compressive spectral renormalization method
(Işık University Press, 2018-09-09)
In this paper a novel numerical scheme for finding the sparse self-localized states of a nonlinear system of equations with missing spectral data is introduced. As in the Petviashivili's and the spectral renormalization ...
Compressive split-step Fourier method
(Işık University Press, 2015-02-09)
In this paper an approach for decreasing the computational effort required for the split-step Fourier method (SSFM) is introduced. It is shown that using the sparsity property of the simulated signals, the compressive ...
On travelling wave solutions of a generalized Davey-Stewartson system
(Oxford Univ Press, 2005-02)
The generalized Davey-Stewartson (GDS) equations, as derived by Babaoglu & Erbay (2004, Int. J. Non-Linear Mech., 39, 941-949), is a system of three coupled equations in (2 + 1) dimensions modelling wave propagation in an ...
