On the Origin of the Tunneling Asymmetry in the Cuprate Superconductors
Tao Li, Fan Yang, Yong-Jin Jiang
We argue the coherent part of the spectral weight always contribute symmetrically to the STM spectrum at sufficiently low energy and the tunneling asymmetry is a manifestation of t…
Magnetic phases of model on triangular lattice
YongJin Jiang, Fan Yang, Tao Li
We study the magnetic properties of the model on triangular lattice in light of the recently discovered superconductivity in NaCoO system. We formulate the proble…
Spin Dynamics of t-J Model on Triangular Lattice
Tao Li, Yong-Jin Jiang
We study the spin dynamics of t-J model on triangular lattice in the Slave-Boson-RPA scheme in light of the newly discovered superconductor NaCoO. We find resonant peak…
A quantum critical point in the transverse field of Mn12 system
Yongjin Jiang, Haijin Li, Ruibao Tao
Using exact diagonalization method,we studied the ground state of the anisotropic molecular magnets and find a critical point in the transverse field,which may divide the quantum t…
