Dynamic and Static Excitations of a Classical Discrete Anisotropic Heisenberg Ferromagnetic Spin Chain
M. Lakshmanan, Avadh Saxena
Using Jacobi elliptic function addition formulas and summation identities we obtain several static and moving periodic soliton solutions of a classical anisotropic, discrete Heisen…
Periodic energy switching of bright solitons in mixed coupled nonlinear Schr{ö}dinger equations with linear self and cross coupling terms
T. Kanna, M. Vijayajayanthi, M. Lakshmanan
The bright soliton solutions of the mixed 2-coupled nonlinear Schr{ö}dinger (CNLS) equations with linear self and cross coupling terms have been obtained by identifying a transform…
Intermittency transition to generalized synchronization in coupled time-delay systems
D. V. Senthilkumar, M. Lakshmanan
In this paper, we report the nature of transition to generalized synchronization (GS) in a system of two coupled scalar piecewise linear time-delay systems using the auxiliary syst…
Trilinearization and Localized Coherent Structures and Periodic Solutions for the (2+1) dimensional K-dV and NNV equations
C. Senthil Kumar, R. Radha, M. Lakshmanan
In this paper, using a novel approach involving the truncated Laurent expansion in the Painlevé analysis of the (2+1) dimensional K-dV equation, we have trilinearized the evolution…
Nonstationary excitations in Bose-Einstein condensates under the action of periodically varying scattering length with time dependent frequencies
S. Rajendran, P. Muruganandam, M. Lakshmanan
We investigate nonstationary excitations in 3D-Bose-Einstein condensates in a spherically symmetric trap potential under the modulation of scattering length with slowly varying fre…
