    • This subtraction also removes an (imaginary) contribution arising from T4(0,0;0), due to the fact that it has to be evaluated at the chemical potential Î, which is not exactly half the bound state energy of the molecule. A similar feature is present in the approach of SPHJAR 0038-5646
    • This subtraction also removes an (imaginary) contribution arising from T4(0,0;0), due to the fact that it has to be evaluated at the chemical potential Î, which is not exactly half the bound state energy of the molecule. A similar feature is present in the approach of S.T. Beliaev, Sov. Phys. JETP SPHJAR 0038-5646 7, 289 (1958) for elementary bosons. More generally there are necessarily, in our handling of the collective mode, clear links with Beliaev’s work since this mode corresponds physically to the elementary boson excitations handled by Beliaev.
