Instability of single- and double-periodic waves in the fourth-order nonlinear Schrödinger equation
N. Sinthuja, S. Rajasekar, M. Senthilvelan
We compute the instability rate for single- and double-periodic wave solutions of a fourth-order nonlinear Schrödinger equation. The single- and double-periodic solutions of a four…
Higher order smooth positon and breather positon solutions of an extended nonlinear Schrödinger equation with the cubic and quartic nonlinearity
S. Monisha, N. Vishnu Priya, M. Senthilvelan +1
We construct certain higher order smooth positon and breather positon solutions of an extended nonlinear Schrödinger equation with the cubic and quartic nonlinearity. We utilize th…
Ghost-Stochastic Resonance in a Unidirectionally Coupled and Small-World Networks
S. Rajamani, S. Rajasekar
Ghost-stochastic resonance is a noise-induced resonance at a missing fundamental frequency in the input signal. In this paper we investigate the features of ghost-stochastic resona…
Vibrational Resonance in the Duffing Oscillator with Distributed Time-Delayed Feedback
C. Jeevarathinam, S. Rajasekar, M. A. F. Sanjuan
We analyze the vibrational resonance in the Duffing oscillator system in the presence of (i) a gamma distributed time-delayed feedback and (ii) integrative time-delayed (uniformly…
Vibrational and Ghost-Vibrational Resonances in A Modified Chua's Circuit Model Equation
K. Abirami, S. Rajasekar, M. A. F. Sanjuan
The role of the number of breakpoints in the sawtooth form of the characteristic function in the modified Chua's circuit model equation on vibrational and ghost-vibrational res…
Enhanced signal propagation in a network with unidirectional and random couplings
S. Rajamani, S. Rajasekar
We investigate the effect of unidirectional regular and random couplings of units in a network on stochastic resonance. For simplicity we choose the units as Bellows map with bista…
