Different kinds of chimera death states in nonlocally coupled oscillators
K. Premalatha, V. K. Chandrasekar, M. Senthilvelan +1
We investigate the significance of nonisochronicity parameter in a network of nonlocally coupled Stuart-Landau oscillators with symmetry breaking form. We observe that the presence…
Impact of symmetry breaking in networks of globally coupled oscillators
K. Premalatha, V. K. Chandrasekar, M. Senthilvelan +1
We analyze the consequences of symmetry breaking in the coupling in a network of globally coupled identical Stuart-Landau oscillators. We observe that symmetry breaking leads to in…
Impact of Current on Static and Kinetic Depinning Fields of Domain Wall in Ferromagnetic Nanostrip
R. Arun, P. Sabareesan, M. Daniel
The impact of current on static and kinetic depinning fields of a domain wall in an one dimensional ferromagnetic nanostrip is investigated by solving the Landau-Lifshitz-Gilbert e…
Analytical soliton solution for the Landau-Lifshitz equation of one dimensional magnonic crystal
D. Giridharan, M. Daniel, P. Sabareesan
Nonlinear localized magnetic excitations in one dimensional magnonic crystal is investigated under periodic magntic field. The governing Landau-Lifshitz equation is transformed int…
Effect of asymmetry parameter on the dynamical states of nonlocally coupled nonlinear oscillators
R. Gopal, V. K. Chandrasekar, D. V. Senthilkumar +2
We show that coexisting domains of coherent and incoherent oscillations can be induced in an ensemble of any identical nonlinear dynamical systems using the nonlocal rotational mat…
Symmetries of nonlinear ordinary differential equations: the modified Emden equation as a case study
M. Senthilvelan, V. K. Chandrasekar, R. Mohanasubha
Lie symmetry analysis is one of the powerful tools to analyze nonlinear ordinary differential equations. We review the effectiveness of this method in terms of various symmetries.…
