  A theoretical analysis of the rotational dynamics induced by off axis binary
collisions of quantum droplets constituted by ultracold atoms is reported. We
focus on quantum droplets formed by degenerate dilute Bose gases made up from
binary mixtures of alkaline atoms under feasible experimental conditions. The
stability of the ground state is known to be longer for the chosen
heteronuclear gases than for the homonuclear ones. In both cases, we find out
that the dynamics seems to privilege a high similarity of the density of each
atomic species. However, the evolution of the phase of the corresponding order
parameter differs significantly for heteronuclear admixtures. We evaluate the
fidelity as a figure of merit for the overlap between the order parameters of
each atomic species. Dynamical evidence of the differences between the phase of
the order parameters are predicted to manifest in their corresponding linear
and angular momenta. We numerically verify that the total angular and linear
momenta are conserved both during the collision. Some direct correlations
between the Weber number and the impact parameter with the distribution of the
dynamical variables are established.
