BaOsO: A Hund's metal in the presence of strong spin-orbit coupling
Max Bramberger, Jernej Mravlje, Martin Grundner +2
We investigate the 5d transition metal oxide BaOsO within a combination of density functional theory (DFT) and dynamical mean-field theory (DMFT), using a matrix-product-state…

SrMoO and SrRuO: Disentangling the Roles of Hund's and van Hove Physics
Jonathan Karp, Max Bramberger, Martin Grundner +3
SrMoO is isostructural to the unconventional superconductor SrRuO but with two electrons instead of two holes in the Mo/Ru-t orbitals. Both materials are Hun…

Open quantum systems in thermal non-ergodic environments
Carlos A. Parra-Murillo, Max Bramberger, Claudius Hubig +1
The dynamics of an open system crucially depends on the correlation function of its environment, . We show that for thermal non-Harmonic environments may not decay…
