Antiferromagnetism and chiral-d wave superconductivity in a honeycomb lattice close to Mott state
Chien-Peng Ho, Khee-Kyun Voo
The antiferromagnetism (AFM) and chiral-d wave superconductivity (SC) in a honeycomb lattice close to an antiferromagnetic (AF) Mott state at half band filling are studied with a t…
An Alternative Interpretation of the Magnetic Penetration Depth Data on Pr(2-x)Ce(x)CuO(4-y) and La(2-x)Ce(x)CuO(4-y)
Khee-Kyun Voo, Wen Chin Wu
We have revisited the magnetic penetration depth data on the electron-doped cuprates Pr(2-x)Ce(x)CuO(4-y) and La(2-x)Ce(x)CuO(4-y). It is proposed that the transition between the n…
Temperature Effect and Fermi Surface Investigation in the Scanning Tunneling Microscopy of BiSrCaCuO
K. -K. Voo, W. C. Wu, H. -Y. Chen +1
Based on a Fermi liquid picture, the temperature effect on the impurity-induced spatial modulation of local density of states (LDOS) is investigated for the d-wave superconductor B…
Comment on ``Relating atomic-scale electronic phenomena to wave-like quasiparticle states in superconducting BiSrCaCuO''
Khee-Kyun Voo, Hong-Yi Chen, W. C. Wu
Comment on ``Relating atomic-scale electronic phenomena to wave-like quasiparticle states in superconducting BiSrCaCuO''
Defect and anisotropic gap induced quasi-one-dimensional modulation of local density of states in YBaCuO
Khee-Kyun Voo, Hong-Yi Chen, W. C. Wu
Motivated by recent angle-resolved photoemission spectroscopy (ARPES) measurement that superconducting YBaCuO (YBCO) exhibits a -symmetry gap, we s…
Spin Excitation in d-wave Superconductors : A Fermi Liquid Picture
K. -K. Voo, H. -Y. Chen, W. C. Wu
A detailed study of the Inelastic Neutron Scattering (INS) spectra of the high- cuprates based on the Fermi liquid (FL) picture is given. We focus on the issue of the transfor…
