    • For low frequencies Nω=N0+N′0ω+⋯ , where Nm0∼N0/Ωm. Substituting this in the preceding equation, we obtain 2 with corrections of order (T/Ω)2. We expect that in our problem Ω≃T* the scale at which the amplitude develops.

    • From an extension of the T=0 analysis by, Phys. Rev. B, 49, 6829, we find dn/dμ=(∂n/∂μ̃)/[1-|U| (∂n/∂μ̃)/2] with ∂n/∂μ̃=Δ2ΣkE-3+(ΣkξE-3)2/ΣkE-3. Here μ̃=μ+〈n〉|U|/2, and the rest of the notation is standard: ξk is the energy measured from μ̃, Δ is the gap, and Ek is the Bogoliubov quasiparticle energy.

    • The parallels between spin charge separation (SCS) in the resonating valence bond picture and in the BCS ground state have been discussed by, Here we find that pairing correlations alone can also give rise to SCS without any broken symmetry.
