Open AccessMott insulators with boundary zeros
The topological classification of electronic band structures is based on symmetry properties of Bloch eigenstates of single-particle Hamiltonians. In parallel, topological field theory has opened the doors to ...

Open AccessMomentum-space signatures of Berry flux monopoles in the Weyl semimetal TaAs
Since the early days of Dirac flux quantization, magnetic monopoles have been sought after as a potential corollary of quantized electric charge. As opposed to magnetic monopoles embedded into the theory of el...

Dynamical Mean Field Theory for Oxide Heterostructures
Transition metal oxide heterostructures often, but by far not always, exhibit strong electronic correlations. State-of-the-art calculations account for these by dynamical mean field theory (DMFT). We discuss t...

Open AccessLocal magnetic moments in iron and nickel at ambient and Earth’s core conditions
Some Bravais lattices have a particular geometry that can slow down the motion of Bloch electrons by pre-localization due to the band-structure properties. Another known source of electronic localization in so...

A microscopic view on the Mott transition in chromium-doped V2O3
V2O3 is the prototype system for the Mott transition, one of the most fundamental phenomena of electronic correlation. Temperature, do** or pressure induce a metal-to-insulator transition (MIT) between a parama...

Phonon softening and dispersion in the 1D Holstein model of spinless fermions
We investigate the effect of electron-phonon interaction on the phononic properties in the one-dimensional half-filled Holstein model of spinless fermions. By means of determinantal Quantum Monte Carlo simula...
