Two-phase sound in superfluid 3He4He mixtures

Research output: Contribution to journalArticlepeer-review


In two-phase sound measurements with 3He4He mixtures, the vapor sound and second sound are found to propagate as independent modes. This result can be traced to a boundary condition of conservation of 3He atoms at the liquid-vapor interface.
