Overview

XDiag is a library for performing Exact Diagonalizations of quantum many-body systems. Key features include optimized combinatorical algorithms for navigating Hilbert spaces, iterative linear algebra algorithms, shared and distributed memory parallelization. It consist of two packages:

• The core C++ library xdiag
• The convenient Julia wrapper library XDiag.jl
