Doping a Bad Metal: Origin of Suppression of Metal-Insulator Transition in Non-Stoichiometric VO
P. Ganesh, Frank Lechermann, Ilkka Kylanpaa +3
Rutile () phase VO is a quintessential example of a strongly correlated bad-metal, which undergoes a metal-insulator transition (MIT) concomitant with a structural transitio…
Oxide Heterostructures from a Realistic Many-Body Perspective
Frank Lechermann
Oxide heterostructures are a new class of materials by design, that open the possibility for engineering challenging electronic properties, in particular correlation effects beyond…
Multi-orbital nature of the spin fluctuations in SrRuO
Lewin Boehnke, Philipp Werner, Frank Lechermann
The spin susceptibility of strongly correlated SrRuO is known to display a rich structure in reciprocal space, with a prominent peak at =. It is sti…
Hidden Mott insulator in metallic PdCrO
Frank Lechermann
There has been a long-standing debate on the coexistence between itinerant electrons and localized spins in the PdCrO delafossite. By means of the charge self-consistent combin…
The role of non-spherical double counting in DFT+DMFT: total energy and structural optimization of pnictide superconductors
Oleg Kristanovski, Alexander Shick, Frank Lechermann +1
A simple scheme for avoiding non-spherical double counting in the combination of density func- tional theory with dynamical mean-field theory (DFT+DMFT)is developed. It is applied…
Uncovering the mechanism of the impurity-selective Mott transition in paramagnetic VO
Frank Lechermann, Noam Bernstein, I. I. Mazin +1
While the phase diagrams of the one- and multi-orbital Hubbard model have been well studied, the physics of real Mott insulators is often much richer, material dependent, and poorl…
