Computational study of model Hamiltonians for the iron-based superconductors
|Date/Time:||Thursday, 21 Nov 2013 - Saturday, 23 Nov 2013|

|Channel:||Condensed Matter Physics|
Recent computational results in the context of models for
the iron-based superconductors will be reviewed. The importance
of including both localized and itinerant degrees of freedom
will be remarked [1,2]. Emphasis will be given to (i) recent
mean-field results that unveiled a variety of exotic magnetic
states in the phase diagrams varying the Hubbard U and Hund J
couplings, and to (ii) a large scale Monte Carlo simulation
of the nematic state above the ordering temperatures for
the parent compounds .
