23. In fact this study used adiabatic de-loading to reduce the temperature of the constituent atoms.
24. For a discussion of how the quantum numbers of quasi-momentum and band index are introduced we refer the reader to Ref. [20].
25. R a is a property of the 3D band structure. In a ID lattice a gap is present for all depths V > 0.
26. This also means that a single component Fermi gas is quite well described by a non-interacting theory.
27. F (the Fermi energy) is the energy of the highest occupied single particle state for the system at T = 0 K.
28. s, so that the excited band isn't occupied by virtue of the Pauli exclusion principle.
29. We note that non-negligible J values in the superfluid regime could be treated using the Hartree-Fock Bogoliubov formalism [21, 22], however we do not consider this regime here.
