v0.2.0

Aug. 15, 2024

Basic functionality for three Hilbert space types, Spinhalf, tJ, and Electron, has been implemented. Features are:

• Algebra with and without permutation symmetries
• Parallelization with OpenMP and MPI
• CMake has been properly set up
• Iterative algorithms present, Lanczos, Arnoldi, time evolution
• A minimal Julia wrapper has been written
• The Julia wrapper compiles on several target 64bit systems using BinaryBuilder
