Ultrafast evolution and transient phases of the prototype out-of-equilibrium Mott-Hubbard material V2O3
G. Lantz, B Mansart, D. Grieger +17
The study of photoexcited strongly correlated materials is attracting growing interest since their rich phase diagram often translates into an equally rich out-of-equilibrium behav…
Low-temperature magnetic ordering and structural distortions in Vanadium Sesquioxide (VO)
Daniel Grieger, Michele Fabrizio
Vanadium Sesquioxide (VO) is an antiferromagnetic insulator below 155 K. The magnetic order is not of C- or G-type as one would infer from the bipart…
How chromium doping affects the correlated electronic structure of V2O3
Daniel Grieger, Frank Lechermann
The archetypical strongly correlated Mott-phenomena compound V2O3 is known to show a paramagnetic metal-insulator transition driven by doping with chromium atoms and/or (negative)…
Electron correlation and magnetism at the LaAlO/SrTiO interface: A DFT+DMFT investigation
Frank Lechermann, Lewin Boehnke, Daniel Grieger +1
We shed light on the interplay between structure and many-body effects relevant for itinerant ferromagnetism in LaAlO/SrTiO heterostructures. The realistic correlated elect…
Formation of orbital-selective electron states in LaTiO/SrTiO superlattices
Frank Lechermann, Lewin Boehnke, Daniel Grieger
The interface electronic structure of correlated LaTiO/SrTiO superlattices is investigated by means of the charge self-consistent combination of the local density approxima…
Approaching finite-temperature phase diagrams of strongly correlated materials: a case study for V2O3
Daniel Grieger, Christoph Piefke, Oleg E. Peil +1
Examining phase stabilities and phase equilibria in strongly correlated materials asks for a next level in the many-body extensions to the local-density approximation (LDA) beyond…
Realistic modeling of the electronic structure and the effect of correlations for Sn/Si(111) and Sn/Ge(111) surfaces
Sergej Schuwalow, Daniel Grieger, Frank Lechermann
The correlated electronic structure of the submonolayer surface systems Sn/Si(111) and Sn/Ge(111) is investigated by density-functional theory (DFT) and its combination with explic…
Electronic correlations in vanadium chalcogenides: BaVSe3 versus BaVS3
Daniel Grieger, Lewin Boehnke, Frank Lechermann
Albeit structurally and electronically very similar, at low temperature the quasi-one-dimensional vanadium sulfide BaVS3 shows a metal-to-insulator transition via the appearance of…
