Abstract.
Using bosonization approach, we derive an effective low-energy theory for XXZ-symmetric spin-1/2 zigzag ladders and discuss its phase diagram by a variational approach. A spin nematic phase emerges in a wide part of the phase diagram, either critical or massive. Possible crossovers between the spontaneously dimerized and spin nematic phases are discussed, and the topological excitations in all phases identified.

It should be remembered that it is only at the SU(2) point that all three components of the vector current satisfy the SU(2)1 Kac-Moody algebra. In the XXZ case (\(\Delta < 1\)) J x R,L and J y R,L acquire anomalous dimensions, and only J z R,L remain as the generators of U(1) R,L .
