Role of diversity in taming chaos in driven memristive arrays

摘要

In this paper we study the effects of noise in computing devices composed by coupled memristive oscillators. In particular, we will focus the attention on the emergence of spatiotemporal chaos in a computing architecture made of simple oscillators composed by three basic elements, namely a capacitor, an inductor and a memristor, driven by a sinusoidal external signal. The characterization of the dynamical behavior of the simple oscillator in terms of flux and charge will be discussed and the counterintuitive role of initial conditions on memristors will be highlighted. Aim of this contribution is to provide evidence that a robust synchronized emergent behavior can be attained as a direct positive consequence of the presence of unavoidable sources of noise on initial conditions.
