There is a growing interest in using cold-atom systems to explore the effectsof strong interactions in topological band structures. Here we investigateinteracting bosons in a Cruetz ladder, which is characterised by topologicalflat energy bands where it has been proposed that interactions can lead to theformation of bound atomic pairs giving rise to pair superfluidity. Byinvestigating realistic experimental implementations, we understand how thelattice topology enhances the properties of bound pairs giving rise torelatively large effective pair-tunnelling in these systems which can lead torobust pair superfluidity, and we find lattice supersolid phases involving onlypairs. We identify schemes for preparation of these phases via time-dependentparameter variation and look at ways to detect and characterise these systemsin a lattice. This work provides a starting point for investigating theinterplay between the effects of topology, interactions and pairing in moregeneral systems, with potential future connections to quantum simulation oftopological materials.
