Observation of Exciton-Phonon Sideband in Individual Metallic Single-Walled Carbon Nanotubes
Hualing Zeng, Hongbo Zhao, Fu-Chun Zhang +1
Single-walled carbon nanotubes (SWCNTs) are quasi-one-dimensional systems with poor Coulomb screening and enhanced electron-phonon interaction, and are good candidates for excitons…
Electron Tunneling in Monolayer and Bilayer Graphene
Di Wu, Weiqiang Chen, Fu-Chun Zhang
Electron's tunneling through potential barrier in monolayer and bilayer graphene lattices is investigated by using full tight-binding model. Emphasis is placed on the resonance tun…
Theory for Superconductivity in Iron Pnictides at Large Coulomb U Limit
Wei-Qiang Chen, Kai-Yu Yang, Yi Zhou +1
Superconductivity in iron pnictides is studied by using a two-orbital Hubbard model in the large U limit. The Coulomb repulsion induces an orbital-dependent pairing between charge…
Narrow superconducting window in Ni-doped LaFeAsO
Guanghan Cao, Shuai Jiang, Xiao Lin +7
We have studied Ni-substitution effect in LaFeNiAsO () by the measurements of x-ray diffraction, electrical resistivity, magnetic susceptibility, and…
Na4Ir3O8 as a 3D spin liquid with fermionic spinons
Yi Zhou, Patrick A. Lee, Tai-Kai Ng +1
Spin liquid states for spin-1/2 antiferromagnetic Heisenberg model on a hyperkagome lattice are studied. We classify and study flux states according to symmetries. Applying this mo…
Symmetry of superconducting states with two orbitals on a tetragonal lattice: application to
Yi Zhou, Weiqiang Chen, Fu-chun Zhang
We use group theory to classify the superconducting states of systems with two orbitals on a tetragonal lattice. The orbital part of the superconducting gap function can be either…
