Uncovering multi-channel magnetic hopfion annihilation via a single-node, billion-spin-scale atomistic framework

Qichen Xu, Anna Delin

Modern atomistic spin simulations combine long stochastic trajectories, thermodynamic sampling, static optimization and multi-image transition-path workflows, all of which rely on…

Electronic Origin of Density Wave Orders in a Trilayer Nickelate

Jiangang Yang, Jun Zhan, Taimin Miao +24

The discovery of superconductivity in Ruddlesden-Popper nickelates has established a new frontier in the study of high-temperature superconductors. However, the underlying pairing…

A general optimization framework for mapping local transition-state networks

Qichen Xu, Anna Delin

Understanding how complex systems transition between states requires mapping the energy landscape that governs these changes. Local transition-state networks reveal the barrier arc…

Design of 2D Skyrmionic Metamaterial Through Controlled Assembly

Qichen Xu, Zhuanglin Shen, Alexander Edström +7

Despite extensive research on magnetic skyrmions and antiskyrmions, a significant challenge remains in crafting nontrivial high-order skyrmionic textures with varying, or even tail…
