超越CMOS计算范式对于解决现代计算机在实现可扩展性、低能耗、降低延迟和增强复杂性方面所面临的问题是必要的。自旋电子系统，利用电子自旋结合其电荷是有前途的候选人，因为他们的低能耗和高速计算架构的硬件实现的演示。磁性Skyrmions是微小的磁性漩涡，由于其具有长期稳定性，小尺寸和各种外部刺激的高效可控性等理想特性，在创新电子设备中具有巨大的潜力。在这个主题回顾中，我们讨论了skyrmions的静态，全局和局部动态特性的基本物理，并概述了利用这些独特特性的计算模型的最新进展。报告还讨论了今后的挑战。
Beyond-CMOS computational paradigms are necessary to solving the problems that we face with modern computers in achieving scalability, low energy consumption, reduced latency, and enhanced complexity. Spintronic systems that exploit electron spin in conjunction with its charge are promising candidates given their demonstration of hardware implementations of low-energy-consumption and high-speed computing architectures. Magnetic skyrmions are tiny magnetic swirls that hold great potential in innovative electronic devices owing to their desirable properties of long-term stability, small size, and highly efficient controllability by various external stimuli. In this topic review, we address the fundamental physics of the static, global and local dynamic properties of skyrmions and provide an overview of recent advances in computational models that utilize these unique properties. A discussion on the challenges lying ahead is also provided.
