- Abstract: We show how to utilize magnetostriction to synchronize two mechanical
vibration modes in a cavity magnomechanical system. The dispersive
magnetostrictive interaction provides necessary nonlinearity required for
achieving synchronization. Strong phase correlation between two mechanical
oscillators can be established, leading to the synchronization robust against
thermal noise. We develop a theoretical framework to analyze the
synchronization by solving the constraint conditions of steady-state limit
cycles. We determine that the strong cavity-magnon linear coupling can enhance
and regulate the synchronization, which offers a new path to modulate
synchronization. The work reveals a new mechanism for achieving and modulating
synchronization and indicates that cavity magnomechanical systems can be an
ideal platform to explore rich synchronization phenomena.

We report on the switching dynamics of both single and coupled VO2-based oscillators, with resistive and capacitive coupling, and explore the capability of their application in neural networks.
For the resistive coupling, it is shown that synchronization takes place at a certain value of the coupling resistance, though it is unstable and a synchronization failure occurs periodically.
For the capacitive coupling, two synchronization modes, with weak and strong coupling, are found. The transition between these modes is accompanied by chaotic oscillations.
