Poincare surface analysis of two coupled quintic oscillators in a single well potential

Abstract

We have investigated the chaotic dynamics of two coupled quintic oscillators in a single well potential as the energy of the oscillator increases, keeping the coupling strength constant. The degree of chaoticity does not increase
monotonously with the energy as regular regions reappear within chaotic seas as the energy increases. After the critical energy, however, the motion becomes fully chaotic.
