Rotational Phonons Drive Low-Energy Kinks in Cuprate Superconductors

Yanyong Wang, Manuel Engel, Christopher Lane +9

Angle-resolved photoemission spectroscopy (ARPES) reveals ubiquitous quasiparticle ``kinks'' near $\sim$70 meV and $\sim$40 meV across cuprate superconductors, often accompanied by…
