Exciton-induced magnons carrying orbital angular momentum in CrI3
Martin Pavelka, Vishal Shokeen, Ruslan Chulkov +15
Magnons are collective spin excitations that contain and transport spin angular momentum in magnetic materials. It has been suggested that they can also carry orbital angular momen…
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…
Mechanical control of magnetic exchange and response in GdRuSi: A computational study
Sagar Sarkar, Rohit Pathak, Arnob Mukherjee +3
We present a systematic computational study of the effect of uniaxial strain on the magnetic properties of GdRuSi, a centrosymmetric material known to host a field-induced…
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…
Unveiling Mysteries of GdRuSi: 3D Magnetism in a layered like Magnet
Sagar Sarkar, Rohit Pathak, Arnob Mukherjee +3
GdRuSi, a centrosymmetric magnet with a square lattice of Gd atoms, hosts a short-period skyrmion square lattice (SkL) without Dzyaloshinskii-Moriya interaction (DMI). RKKY…
Magnon Shake-up: Entanglement Generation and Sensing
Vahid Azimi-Mousolou, Anna Delin, Erik Sjöqvist +1
Shake-up phenomena, rooted in the sudden approximation and many-body quantum dynamics, unveil critical characteristics of quantum systems, with wide-ranging applications in molecul…
