Measurements of the nuclear modification factor ($R_{\mathrm{AA}}$) and the
elliptic flow ($v_{2}$) of muons from heavy-quark decays in Pb+Pb
collisions at $\sqrt{s_{\mathrm{NN}}}$=2.76 TeV from the ATLAS experiment are presented.
The measurements are done over the $p_{\mathrm{T}}$ range of 4-14~GeV and over the
centrality range of (0-60)%. A significance elliptic flow is observed over the full
$p_{\mathrm{T}}$ range for all centralities. The $R_{\mathrm{AA}}$ results are consistent with previous
measurements but have much more statistical precision. More than a
factor of two suppression of the muon yield is observed in most
central collisions. These measurements give us an insight into the
interaction of heavy quarks with the bulk medium produced in heavy-ion
collisions.
