Long-wave asymptotic behavior of the Green's functions of a mixture of superfluids

E. Ya. Denisyuk, Yu. A. Nepomnyashchii


Abstract: The exact form of the Green's functions of a mixture of superfluids is obtained in the long-wave limit with allowance for the infrared divergence of the field diagrams. The manifestations of the infrared anomaly are investigated in the case of a multicomponent superfluid.
