The lead-free halide double perovskite class of materials offers a promising venue for resolving issues related to toxicity of Pb and long-term stability of the lead-containing halide perovskites. We present a first-principles study of the lattice vibrations in Cs_2AgBiBr_6, the prototypical compound in this class and show that the lattice dynamics of Cs_2AgBiBr_6 is highly anharmonic, largely in regards to tilting of AgBr_6 and BiBr_6 octahedra. Using an energy- and temperature-dependent phonon spectral function, we then show h
