摘要：

We study the sound modes of a Bose-Fermi mixture superfluid at finite temperatures in the collisional hydrodynamic regime. We extend Landau's hydrodynamic theory to deal with a Bose-Fermi mixture superfluid and show the existence of three sound modes. We calculate the hydrodynamic sound velocities numerically using the Nozieres and Schmitt-Rink theory at unitarity. The three-sound-modes hybrid in Bose-Fermi mixture superfluids contrasts with the two sound modes exhibited by He-3 and He-4 superfluids.
