Nanoscale magnetic phenomena driven by electron correlations

• Applicant: Professor Dr. Alexander Lichtenstein
• Subject Area: Theoretical Condensed Matter Physics
• Term: from 2015 to 2019
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 267605795

Properties of magnetic atoms adsorbed on metal surfaces, on graphene and on graphene oxide will be studied with the aid of theoretical methods. Emphasis will be put on the effect of strong electron correlations on these properties. The main topic of the research will be magnetic and Kondo behavior as well as its signatures in scanning tunneling microscopy and in photoemission spectra. The influence of spin-orbital coupling will be analyzed. The investigation will employ ab-initio electronic-structure methods, namely the density-functional theory combined with the dynamical-mean-field theory, which accurately describes the electron correlations in d and f atomic shells. The methods will be further developed in the course of the project as required by the chosen applications.
