Pair size and quantum geometry in a multiband Hubbard model
M. Iskin
We study the size of two-body bound states and Cooper pairs within a multiband Hubbard model that features time-reversal symmetry and uniform pairing on a generic lattice. Our anal…

Variational approach for the two-body problem in a multiband extended-Hubbard model
M. Iskin
Considering a spin-up and a spin-down fermion in a generic tight-binding lattice with a multi-site basis, we investigate the two-body problem using a multiband extended-Hubbard mod…
