Importance of effective Coulomb interactions for in cuprates
Jakša Vučičević, 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, Jakša Vučičević, 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…
Charge transfer-induced Lifshitz transition and magnetic symmetry breaking in ultrathin CrSBr crystals
Marco Bianchi, Kimberly Hsieh, Esben Juel Porat +9
Ultrathin CrSBr flakes are exfoliated \emph{in situ} on Au(111) and Ag(111) and their electronic structure is studied by angle-resolved photoemission spectroscopy. The thin flakes'…
Paramagnetic Electronic Structure of CrSBr: Comparison between Ab Initio GW Theory and Angle-Resolved Photoemission Spectroscopy
Marco Bianchi, Swagata Acharya, Florian Dirnberger +9
We explore the electronic structure of paramagnetic CrSBr by comparative first principles calculations and angle-resolved photoemission spectroscopy. We theoretically approximate t…
Inducing a many-body topological state of matter through Coulomb-engineered local interactions
Malte Rösner, Jose L. Lado
The engineering of artificial systems hosting topological excitations is at the heart of current condensed matter research. Most of these efforts focus on single-particle propertie…
Coulomb-Engineered Heterojunctions and Dynamical Screening in Transition Metal Dichalcogenide Monolayers
Christina Steinke, Tim O. Wehling, Malte Rösner
The manipulation of two-dimensional materials via their dielectric environment offers novel opportunities to control electronic as well as optical properties and allows to imprint…
