Gossamer Superconductivity near Antiferromagnetic Mott Insulator in Layered Organic Conductors
J. Y. Gan, Yan Chen, Z. B. Su +1
Layered organic superconductors are on the verge of the Mott insulator. We use Gutzwiller variational method to study a Hubbard model including a spin exchange coupling term. The g…

Entanglement and Quantum Phase Transition in Low Dimensional Spin Systems
Yan Chen, Paolo Zanardi, Z. D. Wang +1
Entanglement of the ground states in and dimerized Heisenberg spin chains as well as in a two-leg spin ladder is analyzed by using the spin-spin concurrence and the entanglem…

Fermi surface evolution in the antiferromagnetic state for the electron-doped t-t'-t''-J model
Qingshan Yuan, Yan Chen, T. K. Lee +1
By use of the slave-boson mean-field approach, we have studied the electron-doped t-t'-t''-J model in the antiferromagnetic (AF) state. It is found that at low doping the Fermi sur…
