14. One may notice that when (Formula presented) Eq. (A1) vanishes and the expression (14) becomes singular. However, this takes place only when the dispersion curve is tangent to the energy zero, i.e., when (Formula presented) Since we are interested in the case of (Formula presented) this will not concern us.
15. This means that there must be phase separation in this fully gapped phase, since in general the h and the l particles can have unequal numbers in the normal state.
