a short, simple public-domain header-only C++ eigensolver library for real symmetric matrices

Symbolic Perturbation Theory (SymPT) is a Python package for symbolic perturbative transformations on quantum systems. SymPT helps compute effective Hamiltonians for both time-independent and time-dependent systems at both operator and matrix level.

quantum circuit systems

A simple algorithm that finds a simultaneous block diagonalization of multiple matrices through the eigendecomposition of a single matrix.

Finding the finest simultaneous block diagonalization of multiple matrices by sequentially exploring invariant subspaces under matrix multiplications. Applications include the efficient analysis of arbitrary synchronization patterns in complex networks.
