Spin-gap phase in the extended t-J chain
Yu-Wen Lee, Yu-Li Lee
We study the one-dimensional deformed model in terms of the continuum field theories. We found that at low doping concentration and far away from the phase separat…

Chern-Simons Theory for Magnetization Plateaus of Frustrated - Heisenberg model
Ming-Che Chang, Min-Fong Yang
The magnetization curve of the two-dimensional spin-1/2 - Heisenberg model is investigated by using the Chern-Simons theory under a uniform mean-field approximation. We f…
