Non-BCS superconductivity for underdoped cuprates by spin-vortex attraction
P. A. Marchetti, F. Ye, Z. B. Su +1
Within a gauge approach to the t-J model, we propose a new, non-BCS mechanism of superconductivity for underdoped cuprates. The gluing force of the superconducting mechanism is an…

Fermion-Spin Transformation to Implement the Charge-Spin Separation
Shiping Feng, Z. B. Su, L. Yu
A novel approach, the fermion-spin transformation to implement the charge-spin separation, is developed to study the low-dimensional - model. In this approach, the charge and…
