The recent discovery of superconductivity in La3Ni2O7 with Tc ~ 80 K under high pressure opens up a new route to high-Tc superconductivity. This material realizes a bilayer square lattice model featuring a strong interlayer hybridization unlike many unconventional superconductors. In this talk, I will present a two-site cluster (dimer) dynamical mean-field theory of La3Ni2O7 focusing on how nonlocal electronic correlations driven by the interlayer hybridization affect the low-energy physics and the concomitant superconductivity.
