We evaluate open heavy-flavor (HF) transport in relativistic heavy-ion
collisions utilizing a strong-coupling treatment for both macro- and
micro-dynamics of the problem . The former is realized through a
hydrodynamic evolution quantitatively constrained by bulk-hadron spectra
and elliptic flow. The HF transport is based on non-perturbative $T$-matrix
calculations of heavy-light parton scattering in the Quark-Gluon Plasma
(QGP) , yielding a diffusion coefficient consistent with lattice QCD,
and on effective interactions of $D$-mesons with light hadrons in hadronic
matter . The $T$-matrix interactions in the QGP lead to resonance
formation close to $T_c$ which are implemented as a hadronization (recombination)
mechanism on a hydrodynamic hypersurface, providing a seamless treatment
of HF interactions throughout the bulk-medium evolution. We deploy this
framework for a comprehensive study of open HF observables from
62-2760 GeV [4,5,6]. A fair description of current experimental data for the
nuclear modification factor and elliptic flow of $D$, $D_s$, $B$ mesons and
HF leptons emerges at low and intermediate transverse momenta $p_T$. Discrepancies
arise toward high $p_T$, indicating the onset of radiative energy loss that we also address via a preliminary nonperturbative bremsstrahlung calculation.
