Logarithmic lift of the su(2)_{-1/2} model
F. Lesage, P. Mathieu, J. Rasmussen +1
This paper carries on the investigation of the non-unitary su(2)_{-1/2} WZW model. An essential tool in our first work on this topic was a free-field representation, based on a c=-…
The su(2)_{-1/2} WZW model and the beta-gamma system
F. Lesage, P. Mathieu, J. Rasmussen +1
The bosonic beta-gamma ghost system has long been used in formal constructions of conformal field theory. It has become important in its own right in the last few years, as a build…
Laughlin's wave functions, Coulomb gases and expansions of the discriminant
P. Di Francesco, M. Gaudin, C. Itzykson +1
In the context of the fractional quantum Hall effect, we investigate Laughlin's celebrated ansatz for the groud state wave function at fractional filling of the lowest Landau level…
Graph Rings and Integrable Perturbations of Superconformal Theories
P. Di Francesco, F. Lesage, J. -B. Zuber
We show that the connection between certain integrable perturbations of superconformal theories and graphs found by Lerche and Warner extends to a broader class. These pertur…
