True random number generation through stochastic magnonic bistability
Mengying Guo, Zhenyu Zhou, Denys Slobodianiuk +13
True random number generators (TRNGs) underpin modern cryptography, yet existing implementations face fundamental trade-offs between speed, scalability, and entropy quality. Here,…
Predictive Indicator of Critical Point in Equilibrium and Nonequilibrium Magnetic Systems
Tianyi Zhang, Caihua Wan, Xiufeng Han
Determining critical points of phase transitions from partial data is essential to avoid abrupt system collapses and reducing experimental or computational costs. However, the comp…
Engineering-Oriented Design of Drift-Resilient MTJ Random Number Generator via Hybrid Control Strategies
Ran Zhang, Caihua Wan, Yingqian Xu +15
Magnetic Tunnel Junctions (MTJs) have shown great promise as hardware sources for true random number generation (TRNG) due to their intrinsic stochastic switching behavior. However…
Bayesian Reasoning Enabled by Spin-Orbit Torque Magnetic Tunnel Junctions
Yingqian Xu, Xiaohan Li, Caihua Wan +8
Bayesian networks play an increasingly important role in data mining, inference, and reasoning with the rapid development of artificial intelligence. In this paper, we present proo…
Probabilistic Greedy Algorithm Solver Using Magnetic Tunneling Junctions for Traveling Salesman Problem
Ran Zhang, Xiaohan Li, Caihua Wan +15
Combinatorial optimization problems are foundational challenges in fields such as artificial intelligence, logistics, and network design. Traditional algorithms, including greedy m…
Visualization of Skyrmion-Superconducting Vortex Pairs in a Chiral-Magnet-Superconductor Heterostructure
Yong-Jie Xie, Ang Qian, Bin He +6
Magnetic skyrmions, the topological states possessing chiral magnetic structure with nontrivial topology, have been widely investigated as a promising candidate for spintronic devi…
