Strong correlation effects in theoretical STM studies of magnetic adatoms
Hung T. Dang, Manuel dos Santos Dias, Ansgar Liebsch +1
We present a theoretical study for the scanning tunneling microscopy (STM) spectra of surface-supported magnetic nanostructures, incorporating strong correlation effects. As concre…
Buried topological edge state associated with interface between topological band insulator and Mott insulator
H. Ishida, A. Liebsch
The electronic structure at the interface between a topological band insulator and a Mott insulator is studied within layer dynamical mean field theory. To represent the bulk phase…
Coulomb correlations in the honeycomb lattice: role of translation symmetry
Ansgar Liebsch, Wei Wu
The effect of Coulomb correlations in the half-filled Hubbard model of the honeycomb lattice is studied within the dynamical cluster approximation (DCA) combined with exact diagona…
Comment on "Absence of spin liquid in non-frustrated correlated systems"
A. Liebsch
In a recent Letter, Hassan and Sénéchal [1] discussed the existence of a spin-liquid phase of the half-filled Hubbard model on the honeycomb lattice. Using schemes, such as the var…
Coulomb blockade and Kondo effect in the electronic structure of Hubbard molecules connected to metallic leads: a finite-temperature exact-diagonalization study
H. Ishida, A. Liebsch
The electronic structure of small Hubbard molecules coupled between two non-interacting semi-infinite leads is studied in the low bias-voltage limit. To calculate the finite-temper…
High-energy pseudogap in degenerate Hubbard model induced via Hund coupling
Ansgar Liebsch
Hund coupling in the degenerate five-band Hubbard model near n=6 occupancy is shown to give rise to a significant depletion of spectral weight above the Fermi level. Calculations w…
