Non-perturbative effects of short-range spatial correlations at the two-particle level
Michael Meixner, Matthias Reitner, Thomas Schäfer +1
By means of cellular dynamical mean-field theory (CDMFT) we study how short-range correlations drive the breakdown of the self-consistent perturbation theory in two-dimensional sys…

Disentangling real space fluctuations: the diagnostics of metal-insulator transitions beyond single-particle spectral functions
Michael Meixner, Marcel Krämer, Nils Wentzell +4
The destruction of metallicity due to the mutual Coulomb interaction of quasiparticles gives rise to fascinating phenomena of solid state physics such as the Mott metal-insulator t…
