Today's #arXivsummary: https://arxiv.org/abs/2308.05285 by Park & Hwang. Authors investigate the temperature- & frequency-dependent optical scattering rates in the pseudogap phase of cuprates via model pseudogap and electron-boson spectral density (EBSD) functions. Fermi liquid-like behavior may be understood by combining contribution from T-dependent EBSD function and the T-dependent pseudogap. #CondMat #arXiv_2308_05285
