Quantum dynamical echo in two-level systems
R. Sankaranarayanan, Jane H. Sheeba, M. Lakshmanan
Evolution of quantum fidelity for two-level systems is studied in the context of periodic echo. From a general treatment for time independent case, we obtain a simple condition on…
Localized Coherent Structures of Ishimori Equation I through Hirota's Bilinearization method:Time dependent/Stationary boundaries
S. Vijayalakshmi, M. Lakshmanan
Ishimori equation is a dimensional generalization of the dimensional integrable classical continuous Heisenberg ferromagnetic spin equation. The richness of the coh…
An unusual Liénard type nonlinear oscillator with properties of a linear harmonic oscillator
V. K. Chandrasekar, M. Senthilvelan, M. Lakshmanan
A Liénard type nonlinear oscillator of the form , which may also be considered as a generalized Emden type equation, is shown to posses…
Symmetries and Integrability Properties of Generalized Fisher Type Nonlinear Diffusion Equation
P. S. Bindu, M. Lakshmanan
Nonlinear reaction-diffusion systems are known to exhibit very many novel spatiotemporal patterns. Fisher equation is a prototype of diffusive equations. In this contribution we in…
