Condensed-Matter Physics & Materials Science Seminar

"Neutron Magnetic Form Factor in Strongly Correlated Materials"

Presented by Maria Pezzoli, Rutgers University

Thursday, February 24, 2011, 1:30 pm — Small seminar room, Bldg. 510

Neutrons are an excellent probe of the physics of unpaired electrons.
We introduce a formalism to compute the neutron magnetic form factor
within a first-principles Density Functional
Theory (DFT) + Dynamical Mean Field Theory (DMFT) calculations.
We use our method to compute the form factor of the heavy fermion superconductor PuCoGa5.
We find that the local physics of this material is described by a mixed
valence mechanism of the type observed in elemental Plutonium.
