Rotational Symmetry Breaking in Sodium Doped Cuprates
Yan Chen, T. M. Rice, F. C. Zhang
For reasonable parameters a hole bound to a Na^{+} acceptor in Ca_{2-x}Na_{x}CuO_{2}Cl_{2} has a doubly degenerate ground state whose components can be represented as states with e…

Exploring Quantum Phase Transitions with a Novel Sublattice Entanglement Scenario
Y. Chen, Z. D. Wang, F. C. Zhang
We introduce a new measure called reduced entropy of sublattice to quantify entanglement in spin, electron and boson systems. By analyzing this quantity, we reveal an intriguing co…

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…
