Our new article, [Beyond-Hubbard Pairing in a Cuprate Ladder](https://journals.aps.org/prx/abstract/10.1103/PhysRevX.15.021049), is now out in Physical Review X. In this paper, we use resonant inelastic x-ray scattering to measure magnetic excitations in a prototypical cuprate ladder, and find evidence for strong hole pairing beyond the Hubbard model. Go check it out!
