Applying experimental constraints to a one-dimensional model for BiS2 superconductivity
M. A. Griffith, K. Foyevtsova, M. A. Continentino +1
Recent ARPES measurements [Phys. Rev. B 92, 041113 (2015)] have confirmed the one-dimensional character of the electronic structure of CeO0.5F0.5BiS2, a representative of BiS2-base…
Role of Degeneracy, Hybridization, and Nesting in the Properties of Multi-Orbital Systems
Andrew Nicholson, Qinlong Luo, Weihao Ge +5
To understand the role that degeneracy, hybridization, and nesting play in the magnetic and pairing properties of multiorbital Hubbard models we here study numerically two types of…
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…
Neutron and ARPES Constraints on the Couplings of the Multiorbital Hubbard Model for the Pnictides
Qinlong Luo, George Martins, Dao-Xin Yao +4
The results of neutron scattering and angle-resolved photoemission experiments for the Fe-pnictide parent compounds, and their metallic nature, are shown to impose severe constrain…
Qualitative understanding of the sign of t' asymmetry in the extended t-J Model and relevance for pairing properties
G. B. Martins, J. C. Xavier, L. Arrachea +1
Numerical calculations illustrate the effect of the sign of the next nearest-neighbor hopping term t' on the 2-hole properties of the t-t'-J model. Working mainly on 2-leg ladders,…
