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…
Nonlinear Dynamics of a Dicke Model for V-Type Atoms
Ofri Adiv, Bernd Krauskopf, Scott Parkins
We study the nonlinear, semiclassical dynamics of an open spin-1 (three-level) variant of the traditional Dicke model. In particular, we focus on V-type energy-level configurations…
