Strange metallicity in the Kagome metal NiIn: a DMFT investigation
Ruslan Mushkaev, Francesco Petocchi, Philipp Werner
Strange metallicity, characterized by a linear temperature dependence of the resistivity, is observed in a broad range of correlated materials, including heavy-fermion compounds an…
Electronic correlations and dynamical screening with ab initio quantum embedding
Chia-Nan Yeh, Francesco Petocchi, Alexander Hampel +4
First-principles descriptions of correlated quantum materials require a simultaneous treatment of strong local many-body effects and nonlocal dynamical screening. We present an eff…
Effect of Interlayer Stacking on the Electronic Properties of 1-TaS
Nelson Hua, Francesco Petocchi, Henry G. Bell +3
Controlled stacking of van der Waals materials is a powerful tool for exploring the physics of quantum condensed matter. Given the small binding between layers, exploitation for en…
Momentum-Resolved Fingerprint of Mottness in Layer-Dimerized NbBr
Mihir Date, Francesco Petocchi, Yun Yen +20
In a well-ordered crystalline solid, insulating behaviour can arise from two mechanisms: electrons can either scatter off a periodic potential, thus forming band gaps that can lead…
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…
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…
Nature of the photo-induced metallic state in monoclinic VO
Jiyu Chen, Francesco Petocchi, Viktor Christiansson +1
The metal-insulator transition of VO, which in equilibrium is associated with a structural phase transition, has been intensively studied for decades. In particular, it is chal…
