Strongly correlated electronic phases encountered in complex oxides exhibit collective carrier dynamics that if properly harnessed can enable novel functionalities and perhaps even new computation paradigms. In this talk, we will present our recent understanding of electronically triggered charge oscillations in a prototypical metal insulator transition (MIT) system, vanadium dioxide. We show that the key to such oscillatory behavior lies in the ability to stabilize a spontaneously reversible phase transition in the complex oxide devices using a negative feedback mechanism. We also explore the synchronization dynamics of such oscillators via experiment and simulation, and investigate its potential for coupled oscillator based non-Boolean associative computing.
