(2022), where a robust numerical evidence of the stability of the Fulde-Ferrell-Larkin-
Ovchinnikov (FFLO) phase of dense spin-polarized Fermi atomic gases in optical lattices was
presented. We are now poised to explore the effects of other terms in the Hamiltonian, like spin-
orbit coupling and in and out-of-plane Zeeman fields. Such terms can be engineered
experimentally in cold atomic Fermi systems, and are expected to open the possibility to observe
exotic superfluid states, with non-trivial topological properties and possible connections with
Majorana fermions. The long-term plan is to interface state-of-the-art Hartree-Fock-Bogoliubov
calculations with correlated Quantum Monte Carlo methodologies. In this presentation, we will
discuss preliminary results, mostly at the mean-field level, to shed light into the different orders
that can emerge in the low-energy landscape of cold atomic systems in optical lattices.
