Experimental Demonstration of Antimonotonicity: The Concurrent Creation and Destruction of Periodic Orbits in a Driven Nonlinear Electronic Resonator

We have experimentally demonstrated antimonotonicity, the concurrent creation and destruction of periodic orbits in a driven nonlinear electronic resonator. A manifestation of antimonotonicity in one-dimensional systems is the formation of dimples in high iterate return maps. Our maps computed from 16-bit resolution time domain data unequivocally exhibit the formation of such dimples.
