Geometry and topological order in the non-relativistic Luttinger liquid
H. V. Kruis, I. P. McCulloch, Z. Nussinov +1
We demonstrate that the notion of spin-charge separation as follows from the Tomonaga-Luttinger theory of relativistic fermions does not suffice to completely specify the Luttinger…

Emergent Z_2 gauge symmetry and spin-charge separation in one dimensional physics
H. V. Kruis, Z. Nussinov, J. Zaanen
We demonstrate that in the scaling limit the phenomenon of spin-charge separation as encountered in Luttinger liquids defined on the lattice can be associated with the emergence of…
