Self-energy-functional theory
Michael Potthoff
Self-energy-functional theory is a formal framework which allows to derive non-perturbative and thermodynamically consistent approximations for lattice models of strongly correlate…
Dynamical Mean-Field Theory of Electronic Correlations in Models and Materials
Dieter Vollhardt
The concept of electronic correlations plays an important role in modern condensed matter physics. It refers to interaction effects which cannot be explained within a static mean-f…
Spin, Orbital, and Spin-Orbital Polarons in Transition Metal Oxides
Krzysztof Wohlfeld
I give a brief overview of a polaron formation in three distinct transition metal oxides: (i) spin polaron when a hole is added to the antiferromagnetic (AF) ordered plane in La$_2…
Polaron in the t-J Models with Three-Site Terms: the SU(2) and the Ising Cases
Krzysztof Wohlfeld
We compare the role of the three-site terms added to the t-J models in the SU(2) and the Ising cases in the extremely low doping regime, i.e. when a single hole added to the strong…
