Anomalous drift of spiral waves in heterogeneous excitable media
S. Sridhar, Sitabhra Sinha, Alexander. V. Panfilov
We study the drift of spiral waves in a simple model of heterogeneous excitable medium, having gradients in local excitability or cellular coupling. For the first time, we report t…

Wave-train induced unpinning of weakly anchored vortices in excitable media
Alain Pumir, Sitabhra Sinha, S. Sridhar +6
A free vortex in excitable media can be displaced and removed by a wave-train. However, simple physical arguments suggest that vortices anchored to large inexcitable obstacles cann…
