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…

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…
