Non-Fermi Liquid due to Orbital Fluctuations in Iron Pnictide Superconductors

Wei-Cheng Lee, Philip W. Phillips

We study the influence of quantum fluctuations on the electron self energy in the normal state of iron-pnictide superconductors using a five orbital tight binding model with genera…

Comment on "High-Spin Polaron in Lightly Doped CuO $_{2}$ Planes"

Wei-Cheng Lee, T. K. Lee

In a recent Letter (Phys. Rev. Lett. 106, 036401 (2011)), Lau, et al. investigated the single hole problem in an effective model containing Cu $d$ and O $2 p$ orbitals by exact diag…

Vacancy Driven Orbital and Magnetic Order in (K,Tl,Cs) $_{y}$ Fe $_{2 - x}$ Se $_{2}$

Weicheng Lv, Wei-Cheng Lee, Philip Phillips

We investigate the effects of the $5 \times 5$ Fe vacancy ordering on the orbital and magnetic order in (K,Tl,Cs) $_{y}$ Fe $_{2 - x}$ Se $_{2}$ using a three-orbital ( $t_{2 g}$ ) t…

Spectral Weight Transfer in Multi-Orbital Mott Systems

Wei-Cheng Lee, Philip W. Phillips

We develop here a general formalism for multi-orbital Mott systems which can be used to understand dynamical and static spectral weight transfer. We find that the spectral weight t…
