Numerical Study of Iron-Based Superconductors and Nematic Order

ORAL

Abstract

We perform an exact diagonlization study of the multi-orbital Hubbard model including coupling to lattice degrees of freedom.The single-particle spectral function, dynamical spin, charge, and Raman response are studied to examine a spin nematic phase due to a biquadratic exchange coupling.
