Designer dynamics through chaotic traps: Controlling complex behavior in driven nonlinear systems
Shakti N. Menon, S. Sridhar, Sitabhra Sinha
Control schemes for dynamical systems typically involve stabilizing unstable periodic orbits. In this paper we introduce a new paradigm of control that involves `trapping' the dyna…
Response to sub-threshold stimulus is enhanced by spatially heterogeneous activity
S. Sridhar, Sitabhra Sinha
Sub-threshold stimuli cannot initiate excitations in active media, but surprisingly as we show in this paper, they can alter the time-evolution of spatially heterogeneous activity…
Controlling spatiotemporal chaos in excitable media using an array of control points
S. Sridhar, Sitabhra Sinha
The dynamics of activation waves in excitable media can give rise to spiral turbulence, the resulting spatiotemporal chaos being associated with empirical biological phenomena such…
Controlling spatiotemporal chaos and spiral turbulence in excitable media: A review
Sitabhra Sinha, S. Sridhar
Excitable media are a generic class of models used to simulate a wide variety of natural systems including cardiac tissue. Propagation of excitation waves in this medium results in…
