Self-consistent +Extended Dynamical Mean Field Theory for semiconductors and insulators
Viktor Christiansson, Francesco Petocchi, Philipp Werner
Theoretical studies of semiconductors and band insulators are usually based on variants of the method without full self-consistency, like single-shot or quasiparticle…
Photo-induced insulator-metal transition in paramagnetic (VCr)O
Jiyu Chen, Francesco Petocchi, Viktor Christiansson +1
Pump-probe experiments with femtosecond time resolution allow to disentangle the electronic dynamics from the lattice response and thus provide valuable insights into the non-equil…
Origin of multiple Lifshitz transitions in the Weyl semi-metal RhSi
Krishnendu Patra, Viktor Christiansson, Ferdi Aryasetiawan +1
It is known from density functional theory (DFT) calculations that RhSi has a multifold degenerate Dirac point at the Fermi energy, with the dominant states in the low-energy regio…
Internal consistency of multi-tier +EDMFT
Ruslan Mushkaev, Francesco Petocchi, Viktor Christiansson +1
The multi-tier +EDMFT scheme is an ab-initio method for calculating the electronic structure of correlated materials. While the approach is free from ad-hoc parameters, it requ…
