“…[1], several theoretical as well as experimental studies have been made pertaining to the existence and characterization of SNAs in different quasiperiodically driven nonlinear dynamical systems. In particular the SNAs have been reported to arise in many physically relevant situations such as the quasiperiodically forced pendulum [2], the quantum particles in quasiperiodic potentials [3], biological oscillators [4], the quasiperiodically driven Duffingtype oscillators [5,6,7,8], velocity dependent oscillators [9], electronic circuits [10,11,12] and in certain maps [13,14,15,16,17,18,19,20,21,22]. Also, these exotic attractors were confirmed by an experiment consisting of a quasiperiodically forced, buckled, magnetoelastic ribbon [23], in analog simulations of a multistable potential [24], and in a neon glow discharge experiment [25].…”
