✦ Synopsis

Theory of the sound absorption of superfluid aIIe-B under arbitrary magnetic field is presented in the collisionless regime. It is shown that the imaginary J = 1, Jz = 0 mode together with pair breaking excitations yield an interesting absorption spectrum depending upon magnetic field.

We suppose that the external magnetic field is applied along z-axis and the distorted order parameter of the B phase is given by [1,2]
