Microscopic model for the ferroelectric field effect in oxide heterostructures
Shuai Dong, Xiaotian Zhang, Rong Yu +2
A microscopic model Hamiltonian for the ferroelectric field effect is introduced for the study of oxide heterostructures with ferroelectric components. The long-range Coulomb inter…

Optical Conductivity Anisotropy in the Undoped Three-Orbital Hubbard Model for the Pnictides
Xiaotian Zhang, Elbio Dagotto
The resistivity anisotropy unveiled in the study of detwinned single crystals of the undoped 122 pnictides is here studied using the two-dimensional three-orbital Hubbard model in…

Competing Pairing Symmetries in a Generalized Two-Orbital Model for the Pnictides
Andrew Nicholson, Weihao Ge, Xiaotian Zhang +6
We introduce and study an extended "t-U-J" two-orbital model for the pnictides that includes Heisenberg terms deduced from the strong coupling expansion. Including these J terms ex…
