second-quantization

sneg is a Mathematica package for performing algebraic calculation with non-commuting operators in many-particle physics

Dynamical Vertex Approximation and Eliashberg equation algorithm for strongly correlated multi-orbital systems

An optimized reimplementation of ArbModel, a nuclear structure diagonalization code originally developed by S. Heinze (2008). This version integrates the Eigen C++ library for fast symmetric matrix diagonalization — up to 100× faster

An efficient and intuitive python package for solving discrete, finite many-body physics problems using exact diagonalization.

This repo contains my work carried out on the summer Internship 2026
