      abstract     = {We report on lattice QCD calculations of the nucleon
                      isovector axial, scalar, and tensor charges. Our
                      calculations are performed on two 2+1-flavor ensembles
                      generated using a 2-HEX-smeared Wilson-clover action at the
                      physical pion mass and lattice spacings $a\approx$ 0.116 and
                      0.093 fm. We use a wide range of source-sink separations -
                      eight values ranging from roughly 0.4 to 1.4 fm on the
                      coarse ensemble and three values from 0.9 to 1.5 fm on the
                      fine ensemble - which allows us to perform an extensive
                      study of excited-state effects using different analysis and
                      fit strategies. To determine the renormalization factors, we
                      use the nonperturbative Rome-Southampton approach and
                      compare RI'-MOM and RI-SMOM intermediate schemes to estimate
                      the systematic uncertainties. Our final results are computed
                      in the MS-bar scheme at scale 2 GeV. The tensor and axial
                      charges have uncertainties of roughly 4\%, $g_T=0.972(41)$
                      and $g_A=1.265(49)$. The resulting scalar charge,
                      $g_S=0.927(303)$, has a much larger uncertainty due to a
                      stronger dependence on the choice of intermediate
                      renormalization scheme and on the lattice spacing.},
