      abstract     = {We present the first calculation of the Mellin moments of
                      the transverse quark spin densities in the nucleon using
                      lattice QCD simulations with physical values of the pion
                      mass and in the continuum limit. Specifically, we use three
                      $N_f=2+1+1$ twisted mass fermion gauge ensembles each at
                      different lattice spacings. The densities are extracted from
                      the unpolarized and transversity generalized form factors.
                      The first moment of transversely polarized quarks in an
                      unpolarized nucleon shows an interesting distortion, which
                      can be traced back to the sharp falloff of the transversity
                      generalized form factor $\bar{B}_{Tn0}(Q^2)$. The isovector
                      tensor anomalous magnetic moment is determined to be
                      $κ_T=1.051(94)$, which confirms a negative and large
                      Boer-Mulders function, $h_1^⊥$, in the nucleon.},
