Frequency locking, Quasi periodicity and Chaos due to special relativistic effects
Derek C. Gomes, G. Ambika
We study quasi periodic and frequency locked states that can occur in a sinusoidally driven linear harmonic oscillator in the special relativistic regime. We show how the shift in…
Fractal Measures and Nonlinear Dynamics of Overcontact Binaries
Sandip V. George, R. Misra, G. Ambika
Overcontact binary stars are systems of two stars where the component stars are in contact with each other. This implies that they share a common envelope of gas. In this work we s…
Frequency locking and travelling burst sequences in community structured network of inhibitory neurons with differing time-scales
Kunal Mozumdar, G. Ambika
We report the emergent dynamics of a community structured modular network of chaotic Hindmarsh-Rose (HR) neurons with inhibitory synapses. We find the inhibitory coupling between t…
Degree weighted recurrence networks for the analysis of time series data
Rinku Jacob, K. P. Harikrishnan, R. Misra +1
Recurrence networks are powerful tools used effectively in the nonlinear analysis of time series data. The analysis in this context is done mostly with unweighted and undirected co…
Dynamics of slow and fast systems on complex networks
Kajari Gupta, G. Ambika
We study the occurrence of frequency synchronised states with tunable emergent frequencies in a network of connected systems. This is achieved by the interplay between time scales…
Nonlinearity in Data with Gaps: Application to Ecological and Meteorological Datasets
Sandip V. George, G. Ambika
Datagaps are ubiquitous in real world observational data. Quantifying nonlinearity in data having gaps can be challenging. Reported research points out that interpolation can affec…
