Today's #arXivsummary: https://arxiv.org/abs/2308.03074 by Luo et. al. Authors utilize the Becchi-Rouet-Stora-Tyutin (BRST) method to quantize a t-J model in a U(1) gauge slave boson representation. Electron distribution & spectral function calculated; non-Fermi liquid behavior agrees with ARPES measurements. #CondMat #arXiv_2308_03074
