Sunny

  • Level of openness 3 ★★★
  • Document quality 3 ★★★
Sunny.jl is a Julia package designed for modeling atomic-scale magnetism, enabling simulations of both equilibrium and non-equilibrium magnetic phenomena from microscopic models. It facilitates the calculation of dynamical spin structure factors, allowing for direct comparisons with experimental scattering data such as neutron or x-ray measurements.
It extends Landau-Lifshitz spin dynamics to treat spins as SU(N) coherent states, making it particularly effective for modeling materials with strong single-ion anisotropy. It provides robust Monte Carlo algorithms for sampling spin configuration in both equilibrium and non-equilibrium dynamics, making it possible to study a wide range of physical phenomena.

ALPS

  • Level of openness 3 ★★★
  • Document quality 3 ★★★

ALPS is a numerical simulation library for strongly correlated systems such as magnetic materials or correlated electrons. It contains typicalsolvers for strongly correlated systems: Monte Carlo methods, exact diagonalization, the density matrix renormalization group, etc. It can be used to calculate heat capacities, susceptibilities, magnetization processes in interacting spin systems, the density of states in strongly correlated electrons, etc. A highly efficient scheduler for parallel computing is another improvement.
