Resonance structure of a periodically forced delay differential equation model for the El Niño--Southern Oscillation
Samuel Bolduc-St-Aubin, Priya Subramanian, Bernd Krauskopf
We study resonance phenomena in the periodically forced Suarez--Schopf delay differential equation, which is a conceptual climate model for the El Niño--Southern Oscillation (ENSO)…
Devil's terraces: determining the organization of resonance tongues in a periodically forced dynamical system
John Bailie, Priya Subramanian, Bernd Krauskopf
In periodically forced dynamical systems, resonance tongues are open regions of a parameter plane in which the dynamics on an invariant torus locks to a stable periodic orbit. Whil…
Regular and chaotic Welander oscillations in a four-dimensional conceptual model for the Atlantic Meridional Overturning Circulation
John Bailie, Priya Subramanian, Bernd Krauskopf
The Atlantic Meridional Overturning Circulation (AMOC) is a key component of the Earth's climate. Evidence indicates a twentieth-century weakening, and enhanced freshwater input to…
Forced symmetry breaking as a mechanism for rogue bursts in a dissipative nonlinear dynamical lattice
Priya Subramanian, Edgar Knobloch, P. G. Kevrekidis
We propose an alternative to the standard mechanisms for the formation of rogue waves in a non-conservative, nonlinear lattice dynamical system. We consider an ODE system that feat…
Snaking without subcriticality: grain boundaries as non-topological defects
Priya Subramanian, Andrew J. Archer, Edgar Knobloch +1
Non-topological defects such as grain boundaries abound in pattern forming systems, arising from local variations of pattern properties such as amplitude, wavelength, orientation,…
Density Distribution in Soft Matter Crystals and Quasicrystals
Priya Subramanian, Daniel J. Ratliff, Alastair M. Rucklidge +1
The density distribution in solids is often represented as a sum of Gaussian peaks (or similar functions) centred on lattice sites or via a Fourier sum. Here, we argue that represe…
