Recent experiments have shown that unconventional superconductivity can
emerge from a normal state with spontaneously
broken time-reversal symmetry. In quantum Hall systems, electrons
exhibit chiral motion, which stabilizes fractional quantum Hall
states in the presence of strong Coulomb repulsion. This naturally
raises the question of whether chiral electrons can also develop
superconductivity driven by repulsive interactions.

Here, we study a spinless fermion model on the dice lattice with a
$2\pi$ flux per unit cell and a large charge-transfer gap. We show that
virtual interband transitions involving the valence band mediate an
effective attractive interaction between conduction-band electrons. As a
result, the system realizes a chiral $p+ip$ superconducting state whose
chirality is locked to that of the underlying normal state. Furthermore,
inserting a $\pi$ flux through the torus changes the fermion parity of
the ground state, indicating the topological nature of the
superconducting phase and the existence of a single Majorana zero mode
at the boundary.
