Abstract摘要
Correlated materials comprise a large part of the innovative landscape due to rich applications and unconventional phases, especially superconductivity. Establishing a minimal microscopic model is a crucial step in designing and discovering these materials. In this talk, I will introduce our recent numerical and quantum computing studies about the necessary components of microscopic models in correlated superconductors. This was motivated by the recent experimental progress in cuprate chains, where we identified a prominent folding feature beyond the predictions of the Hubbard model. With our recently developed hybrid algorithms, we provided a quantitative explanation through the coexistence of strong correlations and electron-phonon coupling. The interplay between these two interactions provides a possible reason for unconventional superconductivity and a control knob to turn it. Finally, I will briefly mention two attempts to increase superconductivity motivated by this mechanism through in-plane strains and ultrafast lasers.
