MA 24: Focus Session: Exploiting spintronics for unconventional computing (joint session MA/TT)

Wednesday, March 14, 2018, 09:30–12:15, H 1012

Over the past century, the miniaturization of electronics has improved commensurately to the growth in computational power following an empirical relationship known as "Moore’s law", an observation that microprocessor performance doubles every 18 months. It has now become clear that this trend will unlikely continue in the future due to limits both in the downscaling of transistors as well as the fundamental throughput of data between CPU and memory elements in traditional Von Neumann computer architectures. A completely new path forward has however been offered by bioinspired approaches to computation which attempt to capture the intrinsic parallelism and energy efficiency exhibited by the animal brain. The past two decades have in fact seen the flourishing of digital machine learning and deep neural network techniques to process data intensive tasks ranging from image recognition to AI development. The next frontier will consist of further optimizing these approaches by designing physical devices capable of implementing these functional principles analogically. Advances in nanomagnetism and spintronics have assembled a versatile toolbox of electrically controllable materials and phenomena whose applications not only integrate seamlessly within current CMOS architectures but also present a radical new horizon for the evolution of device construction and development. The goal of this focus session is to construct a comprehensive picture of the state-of-the-art of spintronic applications to unconventional computing paradigms such as Boltzmann Machines, Neural Network, Probabilistic and Reservoir Computing. The talks will bring together leading scientist in the rapidly evolving field of spintronic computing to highlight the roles that thermally susceptible magnetization dynamics, exotic magnetic textures, frustrated systems and spin waves can play in shaping the computing devices of tomorrow.
