[institut] SCL seminar: Milos Radonjic, Monday, 28 December, 14:00

[Antun Balaz]

Dear colleagues,

You are cordially invited to the Scientific Computing Laboratory seminar, which will be held on Monday, 28 December 2015 at 14:00 in the library reading room of the Institute of Physics Belgrade. The talk entitled

Non-equilibrium transport study of strongly correlated heterostructures

will be given by Dr. Miloš Radonjić (Scientific Computing Laboratory, Institute of Physics Belgrade and Institute of Physics, University of Augsburg). Abstract of the talk:

The effects of local electronic interactions and finite temperatures upon the non-equilibrium transport properties across the metallic heterostructure Cu4CoCu4 are studied. Results are obtained by combining DFT and equilibrium DMFT solver on one side, and DFT and non-equilibrium steady-state impurity solver based on second order perturbation in Hubbard interaction U, on the other side. Results of these two methods are compared for the transmission. It is shown that local, but dynamical electronic correlations reduce the total transmission at the Fermi level, and also increase the spin polarization. The multi-orbital non-equilibrium steady state impurity solver is formulated in the Keldysh Green’s function formalism and allows us an access to all non-equilibrium quantities, such as non-equilibrium steady state current.

Best regards,
Antun Balaž
