[institut] SCL Seminar: Andreas Oestlin Thursday, 8 November, 14:00

[Milos Radonjic]

Dear colleagues,

You are cordially invited to the SCL seminar of the Center for the Study 
of Complex Systems, which will be held on Thursday, 8 November 2018 at 
14:00 in the library reading room “Dr. Dragan Popović" of the Institute 
of Physics Belgrade. The talk entitled

Disorder and Correlation for Realistic Materials: a LDA+DMFT and CPA 
Approach

will be given by Dr. Andreas Oestlin (Institute of physics, University 
of Augsburg, Germany). Abstract of the talk:

We introduce a computational scheme for calculating the electronic 
structure of random alloys that includes electronic correlations within 
the framework of the combined density functional and dynamical 
mean-field theory. By making use of the particularly simple 
parameterization of the electron Green's function within the linearized 
muffin-tin orbitals method, it is possible to greatly simplify the 
embedding of the self-energy. This in turn facilitates the 
implementation of the coherent potential approximation, which is used to 
model the substitutional disorder. The computational technique is tested 
on the Cu-Pd binary alloy system, and for disordered Mn-Ni interchange 
in the half-metallic NiMnSb.
