abstract = {By means of a diffusion Monte Carlo technique, we study one-dimensional unbalanced mixtures of
fermionic Ytterbium atoms (173Yb, 171 Yb). This means clusters in which the total number of 173Yb
particles is different from the sum of all the atoms belonging to the 171 Yb isotope. Our aim will be to
check the possibility of having self-bound arrangements beyond the balanced compositions reported
in previous literature rather than exploring all the situations in which that could be possible. In that
vein, we focused mainly on mixtures in which the atoms belonging to one isotope are spin-polarized,
while the spins of the particles in the other isotope are evenly distributed in two sets. What we
found was that, even tough self-bound droplets are possible for different compositions, the most
stable ones are clusters with a slight excess of attractively interacting 171Yb particles with different
spins with respect to the number of spin-polarized 173 Yb atoms. Clusters in which the number of
repulsively interacting unequal-spin 173Yb atoms are in excess with respect to the spin-polarized
171Yb particles have a very narrow stability range.},
