Spiral wave chimeras in complex oscillatory and chaotic systems
C Gu, G St-Yves, J Davidsen - Physical review letters, 2013 - APS
We demonstrate for the first time that spiral wave chimeras—spiral waves with spatially
extended unsynchronzied cores—can exist in complex oscillatory and even locally chaotic …

Cardiac contraction induces discordant alternans and localized block
In this paper we use a simplified model of cardiac excitation-contraction coupling to study
the effect of tissue deformation on the dynamics of alternans, ie, alternations in the duration …

Pattern formation in reaction-diffusion systems in the presence of non-Markovian diffusion
R Torabi, J Davidsen - Physical Review E, 2019 - APS
We study reaction-diffusion systems beyond the Markovian approximation to take into
account the effect of memory on the formation of spatiotemporal patterns. Using a non …
