The long-range origin of the black hole entropy
Andrea Solfanelli, Francesco Petocchi, Nicolò Defenu
The Sachdev-Ye-Kitaev (SYK) model, has emerged as a powerful tool for exploring the quantum nature of black holes, particularly their residual entropy at zero temperature. In this…
Nature of metallic and insulating domains in the CDW system 1T-TaSe2
M. Straub, F. Petocchi, C. Witteveen +12
We study the electronic structure of bulk 1T-TaSe in the charge density wave phase at low temperature. Our spatially and angle resolved photoemission (ARPES) data show insulati…
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…
Probing enhanced superconductivity in van der Waals polytypes of VTaS
Wojciech R. Pudelko, Huanlong Liu, Francesco Petocchi +15
Layered transition metal dichalcogenides (TMDs) stabilize in multiple structural forms with profoundly distinct and exotic electronic phases. Interfacing different layer types is a…
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…
