摘要:

The equations describing the propagation of acoustic waves in relativistic superfluid two-condensate systems are derived and solved. It is shown that the presence of an additional acoustic mode and two types of waves of fourth sound is a peculiarity of the system under investigation. ©1998 American Institute of Physics.
