Chaotic Attractor Hopping yields Logic Operations
K. Murali, Sudeshna Sinha, Vivek Kohar +2
Certain nonlinear systems can switch between dynamical attractors occupying different regions of phase space, under variation of parameters or initial states. In this work we explo…
Simple nonlinear models suggest variable star universality
John F. Lindner, Vivek Kohar, Behnam Kia +3
Dramatically improved data from observatories like the CoRoT and Kepler spacecraft have recently facilitated nonlinear time series analysis and phenomenological modeling of variabl…
Strange nonchaotic stars
John F. Lindner, Vivek Kohar, Behnam Kia +3
The unprecedented light curves of the Kepler space telescope document how the brightness of some stars pulsates at primary and secondary frequencies whose ratios are near the golde…
Noise Enhanced Activity in a Complex Network
Anshul Choudhary, Vivek Kohar, Sudeshna sinha
We consider the influence of local noise on a generalized network of populations having positive and negative feedbacks. The population dynamics at the nodes is nonlinear, typicall…
Taming Explosive Growth through Dynamic Random Links
Anshul Choudhary, Vivek Kohar, Sudeshna Sinha
We study the dynamics of a collection of nonlinearly coupled limit cycle oscillators, relevant to systems ranging from neuronal populations to electrical circuits, under coupling t…
