We analyze the collective dynamics of an ensemble of globally coupled, externally forced, identical mechanical oscillators with cubic nonlinearity. Focus is put on solutions where the ensemble splits into two internally synchronized clusters, as a consequence of the bistability of individual oscillators. The multiplicity of these solutions, induced by the many possible ways of distributing the oscillators between the two clusters, implies that the ensemble can exhibit multistability. As the…

Multistability in nonlinearly coupled ring of Duffing systems
Abstract In this paper we consider dynamics of three unidirectionally coupled Duffing oscillators with nonlinear coupling function in the form of third degree polynomial. We focus on the influence of
Dynamics of oscillators globally coupled via two mean fields
TLDR
The results indicate that a competition between two coupling channels can lead to a complex system behavior, providing a potential generalized framework for understanding of complex phenomena in natural oscillatory systems.

Dynamical transitions in large systems of mean field-coupled Landau-Stuart oscillators: Extensive chaos and cluster states.
TLDR
This paper study dynamical systems in which a large number N of identical Landau-Stuart oscillators are globally coupled via a mean-field finds that the oscillator population distribution between the clusters continually evolves so that the cluster state is always marginally stable and reveals the mechanism of the discontinuous transition to extensive chaos.
Can hyperchaotic maps with high complexity produce multistability?
TLDR
This work introduces a simple controller on the M-NHM, which can add one more loop in each iteration, to overcome the chaos degradation in the multistability regions.
On multistability behavior of unstable dissipative systems.
TLDR
A structure is proposed where both the linear part and the switching function depend on two parameters, and the range of values of such parameters where the PWL system presents a multistable behavior and trajectories with multiscrolls is shown.
On multistability behavior of unstable dissipative systems
We present a dissipative system with unstable dynamics called unstable dissipative system which are capable of generating a multi-stable behavior, i.e., depending on its initial condition the

Optomechanical multistability in the quantum regime
Classical optomechanical systems feature self-sustained oscillations, where multiple periodic orbits at different amplitudes coexist. We study how this multistability is realized in the quantum
Infinite Multistability in a Self-Reproducing Chaotic System
TLDR
This paper describes a method for constructing self-reproducing systems from a unique class of variable-boostable systems whose coexisting attractors reside in the phase space along a specific coordinate axis and any of which can be selected by choosing an initial condition in its corresponding basin of attraction.
