  Employing nonperturbative transport coefficients for heavy-flavor (HF)
diffusion through quark-gluon plasma (QGP), hadronization and hadronic matter,
we compute $D$- and $B$-meson observables in Pb+Pb ($\sqrt{s}$=2.76\,TeV)
collisions at the LHC. Elastic heavy-quark scattering in the QGP is evaluated
within a thermodynamic $T$-matrix approach, generating resonances close to the
critical temperature which are utilized for recombination into $D$ and $B$
mesons, followed by hadronic diffusion using effective hadronic scattering
amplitudes. The transport coefficients are implemented via Fokker-Planck
Langevin dynamics within hydrodynamic simulations of the bulk medium in nuclear
collisions. The hydro expansion is quantitatively constrained by
transverse-momentum spectra and elliptic flow of light hadrons. Our approach
thus incorporates the paradigm of a strongly coupled medium in both bulk and HF
dynamics throughout the thermal evolution of the system.
