Design Principles for Quasi-Isotropic Exchange in Rare-Earth Quantum Magnets
Kotaro Shimizu, Esteban Agustin Ghioldi, Filip Ronning +1
Rare-earth quantum materials provide a promising platform for emergent phenomena ranging from quantum spin liquids with long-range entanglement to topological magnetic textures. Ho…
Creating and Driving a Twist Soliton on a Magnetic Skyrmion Tube
Shoya Kasai, Kotaro Shimizu, Shun Okumura +1
A magnetic skyrmion tube is a three-dimensional topological soliton formed by stacking two-dimensional skyrmions along the out-of-plane direction. Recent real-space observations of…
Geometric Analysis of Magnetic Labyrinthine Stripe Evolution via Deep Learning Segmentation
VinÃcius Yu Okubo, Kotaro Shimizu, B. S. Shivaram +2
Labyrinthine stripe patterns are common in many physical systems, yet their lack of long-range order makes quantitative characterization challenging. We investigate the evolution o…
Coarsening dynamics of fingerprint labyrinthine patterns: Machine learning assisted characterization
Supriyo Ghosh, Vinicius Yu Okubo, Kotaro Shimizu +3
Fingerprint labyrinthine patterns exhibit a level of structural complexity beyond simple stripe phases, combining local stripe order with a dense network of point-like defects. Unl…
Machine Learning Force-Field Approach for Itinerant Electron Magnets
Sheng Zhang, Yunhao Fan, Kotaro Shimizu +1
We review the recent development of machine-learning (ML) force-field frameworks for Landau-Lifshitz-Gilbert (LLG) dynamics simulations of itinerant electron magnets, focusing on t…
