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…
Plasmon assisted superconductivity in LiTiO
Francesco Petocchi, Viktor Christiansson, Ryotaro Arita +1
We combine plus extended dynamical mean field theory (+EDMFT) with the density functional theory for superconductors (SCDFT) framework to study the electronic properties o…
Spin-stripes in the Hubbard model: a combined DMFT and Bethe-Salpeter analysis
Ruslan Mushkaev, Francesco Petocchi, Shintaro Hoshino +1
The Hubbard model is known to accommodate various electronic orders, including stripes, which are important for understanding the physics of cuprates. We study spin-stripe order in…
Next-generation EDIpack: A Lanczos-based package for quantum impurity models featuring general broken-symmetry phases, flexible bath topologies and multi-platform interoperability
Lorenzo Crippa, Igor Krivenko, Samuele Giuli +10
We present a next-generation version of EDIpack, a flexible, high-performance numerical library using Lanczos-based exact diagonalization to solve generic quantum impurity problems…
Ultrafast Electronic Structure Engineering in 1-TaS: Role of Doping and Amplitude Mode Dynamics
J. Jayabalan, Jiyu Chen, Laura Pätzold +12
In strongly correlated transition metal dichalcogenides, an intricate interplay of polaronic distortions, stacking arrangement, and electronic correlations determines the nature of…
