High-order synchronization in a system of nonlinearly coupled Stuart-Landau oscillators

Nissi Thomas, S. Karthiga, M. Senthilvelan

The high-order synchronization was studied in systems driven by external force and in autonomous systems with proper frequency mismatch. Differing from the literature, in this arti…

Frustration induced transient chaos, fractal and riddled basins in coupled limit cycle oscillators

K. Sathiyadevi, S. Karthiga, V. K. Chandrasekar +2

This report unravels frustration as a source of transient chaotic dynamics even in a simple array of coupled limit cycle oscillators. The transient chaotic dynamics along with the…

Quantum solvability of a general ordered position dependent mass system: Mathews-Lakshmanan oscillator

S. Karthiga, V. Chithiika Ruby, M. Senthilvelan +1

In position dependent mass (PDM) problems, the quantum dynamics of the associated systems have been understood well in the literature for particular orderings. However, no efforts…

Spontaneous symmetry breaking due to the trade-off between attractive and repulsive couplings

K. Sathiyadevi, S. Karthiga, V. K. Chandrasekar +2

Spontaneous symmetry breaking (SSB) is an important phenomenon observed in various fields including physics and biology. In this connection, we here show that the trade-off between…

Controlling of blow-up responses by a nonlinear symmetric coupling

S. Karthiga, V. K. Chandrasekar, M. Senthilvelan +1

We investigate the dynamics of a coupled waveguide system with competing linear and nonlinear loss-gain profiles which can facilitate power saturation. We show the usefulness of th…

Systems that become symmetric through interaction

S. Karthiga, V. K. Chandrasekar, M. Senthilvelan +1

In this article, we consider an interesting class of optical and other systems in which the interaction or coupling makes the systems to be -symmetric. We aim to compare…

Feedback as a mechanism for the resurrection of oscillations from death state

V. K. Chandrasekar, S. Karthiga, M. Lakshmanan

The quenching of oscillations in interacting systems leads to several unwanted situations, which necessitate a suitable remedy to overcome the quenching. In this connection, this w…

Bi- symmetry in nonlinearly damped dynamical systems and tailoring regions with position dependent loss-gain profiles

S. Karthiga, V. K. Chandrasekar, M. Senthilvelan +1

We investigate the remarkable role of position dependent damping in determining the parametric regions of symmetry breaking in nonlinear -symmetric systems. We illustrate…

Ladder operators and squeezed coherent states of a 3-dimensional generalized isotonic nonlinear oscillator

V. Chithiika Ruby, S. Karthiga, M. Senthilvelan

We explore squeezed coherent states of a 3-dimensional generalized isotonic oscillator whose radial part is the newly introduced generalized isotonic oscillator whose bound state s…
