• Abstract: We find an unexpected phenomenon of coherently synchronized oscillations in a mirror-symmetric many-body localized system. A synchronization transition of the spin oscillations is found by changing the spin-spin interactions. To understand this phenomenon, an effective Ising model based on local integrals of motion is proposed. We find that the synchronization transition can be understood as a paramagnetic-to-ferromagnetic Ising transition. Based on the Ising model, we theoretically estimate the synchronized frequencies and the synchronization transition points, which agree well with numerical results.

  In the presence of heterogeneous data, where randomly rotated objects fall into multiple underlying categories, it is challenging to simultaneously classify them into clusters and synchronize them based on pairwise relations. We propose a series of semidefinite relaxations, and prove their exact recovery when extending the celebrated block model to this new setting. Numerical experiments demonstrate the efficacy of our proposed algorithms and confirm our theoretical result which indicates a sharp phase transition for exact recovery.

  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.

• Thermal coupling and effect of subharmonic synchronization in a system of two VO2 based oscillators [55.41644538483948]
  We explore a prototype of an oscillatory neural network (ONN) based on vanadium dioxide switching devices. The effective action radius RTC of coupling depends both on the total energy released during switching and on the average power. In the case of a strong thermal coupling, the limit of the supply current parameters, for which the oscillations exist, expands by 10 %. The effect of subharmonic synchronization hold promise for application in classification and pattern recognition.
