Nanomagnetic Artificial Spin Systems for Neuromorphic Computing & Reconfigurable Magnonics
Neuromorphic Computing& Magnonics with Nanomagnetic Arrays
As Moore's law breaksdown and the energy demands of computing skyrocket, we urgently need radicalnew solutions for information storage and processing.
Increasingly, researchersare trying to harness the dynamic interactions of complex physical systems toprovide this next-generation, low-energy processing. The vast microstate spaceof artificial spin ice (ASI) & related nanomagnetic arrays is both hugelypowerful for diverse processing and functionality, and highly challenging toexperimentally reconfigure into more than a handful of states. At ImperialCollege London, we work with Kilian Stenning, Will Branford & Alex Vanstoneon combining an expanding suite of ASI microstate control techniques withASI-based functional systems including reconfigurable magnonic crystals [1-4],neuromorphic computing [4,5] and nanomagnetic writing [6,7]. In this seminar wewill see how the physical dynamics of nanomagnetic systems can be harnessed forcomputing in ASI and Skyrmion systems across a range of physical phases andarray architectures.
