How to determine model Hamiltonians for strongly correlated materials
Marie-Bernadette Lepetit
The present paper reviews recent achievements on the ab initio determination of effective model Hamiltonians aimed at the description of strongly correlated materials. These models…

Density-matrix renormalization study of the Hubbard model on a Bethe lattice
Marie-Bernadette Lepetit, Maixent Cousy, G. M. Pastor
The half-filled Hubbard model on the Bethe lattice with coordination number is studied using the density-matrix renormalization group (DMRG) method. Ground-state properties s…
