Metal and insulator states of SU(6) × SU(2) clusters of fermions in one-dimensional optical lattices

We studied the behavior of mixtures of 173 Yb (with symmetry up to SU(6)) and 171 Yb (up to SU(2)) fermionic isotopes loaded in one-dimensional (1D) optical lattices. To do so, we solved the Schrödinger equation describing different systems using a diffusion Monte Carlo technique. We considered continuous Hamiltonians in which the interactions between atoms of different species (isotopes and/or spins) were modeled by contact potentials with...
