[institut] SCL seminar: Sasa Dordevic, Tuesday, 28 June 2016, 12:00

[Darko Tanaskovic]

Dear colleagues,

You are cordially invited to the Scientific Computing Laboratory
seminar, which will be held on Tuesday, 28 June 2016 at 12:00 in the
library reading room “Dr. Dragan Popović" of the Institute of Physics
Belgrade. The talk entitled


Electron-boson spectral function in the cuprates

will be given by Prof. Dr. Sasa Dordevic (The University of Akron, 
USA).

Abstract of the talk:

Electron-boson (Eliashberg) spectral function is one of the most
important properties of a BCS superconductor. In conventional
superconductors the electron-phonon spectral function was
successfully obtained from tunneling and infrared spectroscopy. The
situation is more complicated in cuprates where the mechanism of
superconductivity is still a matter of debate. Based on infrared
data, it was suggested that charge carriers in cuprates might be
strongly coupled to some collective bosonic mode, probably of
magnetic origin. In this talk I will first review the existing
procedures for extracting the electron-boson spectral function in
the cuprates and other superconductors. I will then discuss a new
procedure that we are currently working on.


Best regards,
Darko Tanaskovic
