Compact numerical solutions to the two-dimensional repulsive Hubbard model obtained via non-unitary similarity transformations

Werner Dobrautz, Hongjun Luo, Ali Alavi

The paper applies a Gutzwiller‑based non‑unitary similarity transformation to the 2D repulsive Hubbard model, yielding a compact non‑Hermitian Hamiltonian whose right eigenvectors…

Similarity transformation of the electronic Schrödinger equation via Jastrow factorisation

Aron J. Cohen, Hongjun Luo, Kai Guther +3

The paper derives a similarity‑transformed, non‑Hermitian effective Hamiltonian using Jastrow‑factorised wavefunctions and solves it with stochastic configuration interaction, achi…
