Query: Synthetic superfluid chemistry with vortex-trapped quantum impurities   We explore the effect of using two-dimensional matter-wave vortices to
confine an ensemble of bosonic quantum impurities. This is modelled
theoretically using a mass-imbalanced homogeneous two component
Gross-Pitaevskii equation where each component has independent atom numbers and
equal atomic masses. By changing the mass imbalance of our system we find the
shape of the vortices are deformed even at modest imbalances, leading to barrel
shaped vortices; which we quantify using a multi-component variational
approach. The energy of impurity carrying vortex pairs are computed, revealing
a mass-dependent energy splitting. We then compute the excited states of the
impurity, which we in turn use to construct `covalent bonds' for vortex pairs.
Our work opens a new route to simulating synthetic chemical reactions with
superfluid systems.
