THE NONLINEAR DYNAMICS OF A LINEAR CLASSICAL OSCILLATOR COUPLED TO A MACROSCOPIC QUANTUM OBJECT

Abstract
In this paper we will discuss a model for the behavior of an rf-SQUID magnetometer, which consists of a macroscopic quantum object which is reactively coupled to a linear classical oscillator. We demonstrate that the coupling between the quantum object and the classical oscillator can lead to manifestly nonlinear behavior in the otherwise linear oscillator; including multi-periodic and chaotic solutions.
