Spectra of Conformal Field Theories with Current Algebras
T. Gannon, P. Ruelle, M. A. Walton
This is an elementary review of our recent work on the classification of the spectra of those two-dimensional rational conformal field theories (RCFTs) whose (maximal) chiral algeb…

Algebraic Aspects of Abelian Sandpile Models
D. Dhar, P. Ruelle, S. Sen +1
The abelian sandpile models feature a finite abelian group G generated by the operators corresponding to particle addition at various sites. We study the canonical decomposition of…

On the General Structure of Hamiltonian Reductions of the Wznw Theory
L. Feher, L. O'raifeartaigh, P. Ruelle +2
The structure of Hamiltonian reductions of the Wess-Zumino-Novikov-Witten (WZNW) theory by first class Kac-Moody constraints is analyzed in detail. Lie algebraic conditions are giv…
