Wakimoto construction for double loop algebras and -function regularisation
Tommaso Franzini
The Feigin-Frenkel homomorphism underpinning the Wakimoto construction realises an affine Lie algebra at critical level in terms of the -system of free fields. It was recently…

Hagedorn singularity in exact U_q(su(2)) S-matrix theories with arbitrary spins
Changrim Ahn, Tommaso Franzini, Francesco Ravanini
Generalizing the quantum sine-Gordon and sausage models, we construct exact S-matrices for higher spin representations with quantum U_q(su(2)) symmetry, which satisfy unitarity, cr…
