Title: | Role of magnetic skyrmions for the solution of the shortest path problem | Journal: | Journal of Magnetism and Magnetic Materials | Series/Report no.: | /532 (2021) | Publisher: | Elsevier | Issue Date: | 31-Mar-2021 | DOI: | 10.1016/j.jmmm.2021.167977 | URL: | http://arxiv.org/pdf/2103.02949 | Keywords: | Physics - Mesoscopic Systems and Quantum Hall Effect; Physics - Mesoscopic Systems and Quantum Hall Effect | Abstract: | Magnetic skyrmions are emerging as key elements of unconventional operations having unique properties such as small size and low current manipulation. In particular, it is possible to design skyrmion-based neurons and synapses for neuromorphic computing in devices where skyrmions move along the current direction (zero skyrmion Hall angle). Here, we show that, for a given graph, skyrmions can be used in optimization problems facing the calculation of the shortest path. Our tests show a solution with the same path length as computed with Algorithm. In addition, we also discuss how skyrmions act as positive feedback on this type of problem giving rise to a self-reinforcement of the path which is a possible solution. |
