Sunny.jl: A Julia Package for Spin Dynamics

Le résumé fourni par la source

Sunny is a Julia package designed to serve the needs of the quantum magnetism community.It supports the specification of a very broad class of spin models and a diverse suite of numerical solvers.These include powerful methods for simulating spin dynamics both in and out of equilibrium.Uniquely, it features a broad generalization of classical and semiclassical approaches to SU(N) coherent states, which is useful for studying systems exhibiting strong spin-orbit coupling or local entanglement effects.Sunny also offers a well-developed framework for calculating the dynamical spin structure factor, enabling direct comparison with scattering experiments.Ease of use is a priority, with tools for symmetry-guided modeling and interactive visualization.
