Pairing dome from an emergent Feshbach resonance in a strongly repulsive bilayer model
Understanding unconventional superconductivity involves unraveling the pairing mechanism of charge carriers in doped antiferromagnets, where Cooper pairs form despite repulsive interactions. This paper examines a model relevant to bilayer nickelate superconductors, revealing a transition from tightly bound to spatially extended pairs as repulsion increases. At strong repulsion, a microscopic pairing mechanism is identified that leads to robust pairing with a peak in binding energies at around 30% doping, which can be tested using quantum simulators.
