Increasing superconducting $T_{c}$ by layering in the attractive Hubbard model

Rodrigo A. Fontenele, Natanael C. Costa, Thereza Paiva +1

The attractive Hubbard model has become a model readily realizable with ultracold atoms on optical lattices. However, the superconducting (superfluid) critical temperatures, $T_{c}$ '…

Size and shape of Mott regions for fermionic atoms in a two-dimensional optical lattice

Tiago Mendes-Santos, Thereza Paiva, Raimundo R. dos Santos

We investigate the harmonic-trap control of size and shape of Mott regions in the Fermi Hubbard model on a square optical lattice. The use of Lanczos diagonalization on clusters wi…
