Welcome

Sunny provides powerful tools to simulate equilibrium and non-equilibrium magnetic phenomena from microscopic models. It also facilitates calculation of the dynamical spin structure factor $\mathcal{S}(𝐪,ω)$ for direct comparison to experimental scattering data.

Feature highlights include symmetry-guided modeling, interactive visualization, and more accurate approximations to quantum spin dynamics.
