Z_2 Gauge Theory of Electron Fractionalization in the t,t'-J Model

D. Schmeltzer, A. R. Bishop

We consider a strongly correlated "t,t'-J" spin model with a positive uniaxial anisotropy. We show that in 2+1 dimensions, this model is equivalent to spin-charge excitations coupled to Z_2 Ising gauge fields and not to a U(1) gauge fields (as in the "t-J" model). As a result a phase of frozen Z_2 gauge fluctuations is possible, giving rise to a spin-charge-separated liquid.

Statistics of holons and spinons in the t-J model

Ikuo Ichinose, Tetsuo Matsui, Sakakibara, K.

We study the statistics of holons and spinons in the framework of the gauge theory. We start with the t-J model in the slave-boson formalism and use Chern-Simons gauge theory to study the statistics transmutation of quasiexcitations in the charge-spin separated phase.
