Chimera states: The Existence Criteria Revisited
Gautam C Sethia, Abhijit Sen
Chimera states, representing a spontaneous break-up of a population of identical oscillators that are identically coupled, into sub-populations displaying synchronized and desynchr…
Amplitude death in networks of delay-coupled delay oscillators
Johannes M. Höfener, Gautam C. Sethia, Thilo Gross
Amplitude death is a dynamical phenomenon in which a network of oscillators settles to a stable state as a result of coupling. Here, we study amplitude death in a generalized model…
Experimental observation of extreme multistability in an electronic system of two coupled Rössler oscillators
Mitesh S. Patel, Unnati Patel, Abhijit Sen +7
We report the first experimental observation of extreme multistability in a controlled laboratory investigation. Extreme multistability arises when infinitely many attractors coexi…
Phase locked solutions and their stability in the presence of propagation delays
Gautam C Sethia, Abhijit Sen, Fatihcan M Atay
We investigate phase-locked solutions of a continuum field of nonlocally coupled identical phase oscillators with distance-dependent propagation delays. Equilibrium relations for b…
Coherence Resonance in an Autapse Neuron Model with Time Delay
Gautam C Sethia, Juergen Kurths, Abhijit Sen
We study the noise activated dynamics of a model {\it autapse} neuron system that consists of a subcritical Hopf oscillator with a time delayed nonlinear feedback. The coherence of…
Bursting in a Subcritical Hopf Oscillator with a Nonlinear Feedback
Gautam C Sethia, Abhijit Sen
Bursting is a periodic transition between a quiescent state and a state of repetitive spiking. The phenomenon is ubiquitous in a variety of neurophysical systems. We numerically st…
