Battogtokh in 2002 in a one-dimensional network of complex Ginzburg–Landau equations …

Chimera states in neuronal networks: A review

S Majhi, BK Bera, D Ghosh, M Perc - Physics of life reviews, 2019 - Elsevier
Neuronal networks, similar to many other complex systems, self-organize into fascinating
emergent states that are not only visually compelling, but also vital for the proper functioning …

Chimera states: effects of different coupling topologies

BK Bera, S Majhi, D Ghosh, M Perc - Europhysics Letters, 2017 - iopscience.iop.org
Collective behavior among coupled dynamical units can emerge in various forms as a result
of different coupling topologies as well as different types of coupling functions. Chimera …

Higher-order interactions promote chimera states

S Kundu, D Ghosh - Physical Review E, 2022 - APS
Since the discovery of chimera states, the presence of a nonzero phase lag parameter turns
out to be an essential attribute for the emergence of chimeras in a nonlocally coupled …

Excitation and suppression of chimera states by multiplexing

VA Maksimenko, VV Makarov, BK Bera, D Ghosh… - Physical Review E, 2016 - APS
We study excitation and suppression of chimera states in an ensemble of nonlocally coupled
oscillators arranged in a framework of multiplex network. We consider the homogeneous …
