A State-Specific Iterative Decoupling Scheme Based on Perturbation Theory for Low-Energy Electronic States

Oussama Bindech, Saad yalouz, Vincent Robert

In this work, we introduce a selective and scalable extension of the multi-step Rayleigh-Schrodinger and Brillouin-Wigner perturbative scheme (see arXiv:2408.16505), designed to ef…
