A Luttinger-Ward analysis of the slave-rotor formalism is developed to compute Green's functions and thermodynamic properties in the U(1) spin liquid phase of the Hubbard model beyond mean-field.
Radiative corrections applied to MINERvA antineutrino data yield updated values for the nucleon axial-vector form factor G_A and axial radius.
The paper reviews the use of the imaginary-time correlation function to extract temperature, normalization, and Rayleigh weight from XRTS spectra without model dependence.
