Importance of effective Coulomb interactions for in cuprates
JakÅ¡a VuÄiÄeviÄ, Upendra Kumar, Chia-Nan Yeh +2
Cuprate superconductors exhibit the highest observed superconducting at atmospheric pressure. However, the magnitude of varies significantly between different cuprates.…
Change in charge density wave order beyond the Lifshitz transition in 2H-Ta\textsubscript{1}S\textsubscript{2}
Mihir Date, Jan Berges, Enrico Da Como +6
We investigate electronic instabilities in 2H-TaS\textsubscript{2} and a self-intercalated variant, 2H-Ta\textsubscript{1+}S\textsubscript{2}. In conventional samples…
Exact downfolding and its perturbative approximation
Jonas B. Profe, JakÅ¡a VuÄiÄeviÄ, P. Peter Stavropoulos +3
Solving the many-electron problem, even approximately, is one of the most challenging and simultaneously most important problems in contemporary condensed matter physics with vario…
Static treatment of dynamic interactions in the single-orbital Anderson impurity model
Anton Pauli, Akshat Mishra, Malte Rösner +1
Correlated electron physics is intrinsically a multiscale problem, since high-energy electronic states screen the interactions between the correlated electrons close to the Fermi l…
From strong to weak correlations in breathing-mode kagome van der Waals materials: Nb(F,Cl,Br,I) as a robust and versatile platform for many-body engineering
Joost Aretz, Sergii Grytsiuk, Xiaojing Liu +12
By combining ab initio downfolding with cluster dynamical mean-field theory, we study the degree of correlations in monolayer, bilayer and bulk breathing-mode kagome van der Waals…
Enhancing Plasmonic Superconductivity in Layered Materials via Dynamical Coulomb Engineering
Yann in 't Veld, Mikhail I. Katsnelson, Andrew J. Millis +1
Conventional Coulomb engineering, through controlled manipulation of the environment, offers an effective route to tune the correlation properties of atomically thin van der Waals…
