Abstract: S1.00281 : The Itinerant Electron and Local Moment Hybrid Model of Iron-based Superconductors
Author:
An itinerant electron and local moment hybrid model for iron-based
superconductors is studied, with the band structure modeled simply
by two pockets. Reasonable phase diagram is obtained on the mean
field level. The spin and charge dynamics are further studied by
the random phase approximation (RPA). The dynamic spin
susceptibility displays a Goldstone mode of the collective
itinerant electron and local moment excitations in the SDW phase,
and a resonance mode in the superconducting phase which persists
all the way to the normal state phase. It is found that the
scattering with local moment always tends to reduce the pocket
depth of the itinerant electron. The study also suggests that, to
correctly account for the features in transport experiments, the
multi-band effect that give rise to the nodal SDW should be
included.
