SCL Seminar by Sasa Djordjevic
Scientific Computing Laboratory seminar 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. Saša Đorđevic (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.
