Chimera states for a globally coupled sine circle map lattice: spatiotemporal intermittency and hyperchaos
Joydeep Singha, Neelima Gupte
We study the existence of chimera states, i.e. mixed states, in a globally coupled sine circle map lattice, with different strengths of inter-group and intra-group coupling. We fin…
Chimera states in coupled map lattices: Spatiotemporally intermittent behavior and an equivalent cellular automaton
Joydeep Singha, Neelima Gupte
We study the existence of chimera states, i.e. mixed states, in a globally coupled sine circle map lattice, with different strengths of inter-group and intra-group coupling. We fin…
Synchronization, phase slips and coherent structures in area-preserving maps
Swetamber Das, Sasibhusan Mahata, Neelima Gupte
The problem of synchronization of coupled Hamiltonian systems exhibits interesting features due to the non-uniform or mixed nature (regular and chaotic) of the phase space. We stud…
Dynamics of impurities in a three-dimensional volume-preserving map
Swetamber Das, Neelima Gupte
We study the dynamics of inertial particles in three dimensional incompressible maps, as representations of volume preserving flows. The impurity dynamics has been modeled, in the…
Chimera states in coupled sine-circle map lattices
Chitra R Nayak, Neelima Gupte
Systems of coupled oscillators have been seen to exhibit chimera states, i.e. states where the system splits into two groups where one group is phase locked and the other is phase…
