Title: Mutually synchronized spin Hall nano-oscillators for neuromorphic computing and Ising machines
Abstract:

Mutually synchronized spin hall nano-oscillators (SHNOs) [1,2] have emerged as one of the most promising types of spintronic devices for neuromorphic computing as individual SHNOs in large arrays can be voltage [3] and memristor [4] controlled. Very recently, the first experimental steps towards SHNO-based Ising Machines were also taken [5], and their potential was evaluated theoretically [6]. In my talk, I will describe our recent work in this field and the challenges that have to be overcome before SHNO-based Ising Machines can become a reality.
