    • The rotation necessarily involves both the physical electron and quasiparticle orbital basis: these, in fact, must coincide in the present representation, in accordance to the matching between physical and QP Fock states imposed by Eq. 3.

    • To be precise, the transformation law of Ai0 yields L→L+i i τ ξi0 (τ), which corresponds to a phase shift of the action S→S+i i [ξi0 (β) - ξi0 (0)]. However, the periodic boundary conditions on the boson fields imply that ξi0 (β) = ξi0 (0) mod2π so that e-S remains invariant.
