The exact renormalisation group equation and the perturbed unitary minimal models

Lars Kjærgaard
2000 Journal of High Energy Physics  
The exact renormalisation group equation is studied for a two-dimensional theory with exponential interaction and a background charge at infinity. The motivation for studying this interaction is the flow between unitary minimal models perturbed by Phi_(1,3), and their realisation in terms of a quantum group restricted sine-Gordon model.
