TRIQS arbitrary Crossing Approximation (XCA) impurity solver

Julia scripts run and visualise the H atom scattering from Germanium(111) surface simulation via an 1-D analytical non-adiabatic effects embedded model. Reproduction of the conjugate paper's figures.

An NCA-based solver for the dissipative Anderson impurity model, with applications to nonequilibrium and open quantum impurity problems.

The prototype version of the bold hybridization quantum monte carlo (BHQMC) impurity solver for dynamical mean field theory. Finished March 2025.

An Anderson impurity model solver based on the cumulant Green's functions method

Anderson Hamiltonian diagonalization by NRG calculations

Variational Quantum Eigensolver for single-impurity Anderson models (SIAM) in Qiskit, validated against EDRIXS exact diagonalization, with an IBM Quantum hardware path.
