Universality Classes of Diagonal Quantum Spin Ladders
M. A. Martin-Delgado, J. Rodriguez-Laguna, G. Sierra
We find the classification of diagonal spin ladders depending on a characteristic integer in terms of ferrimagnetic, gapped and critical phases. We use the finite algorithm D…

Renormalization group limit-cycles and field theories for elliptic S-matrices
Andre LeClair, German Sierra
The renormalization group for maximally anisotropic su(2) current interactions in 2d is shown to be cyclic at one loop. The fermionized version of the model exhibits spin-charge se…
