Open Quantum Cluster Embedding Theory
Petar BriniÄ, Hugo U. R. Strand, JakÅ¡a VuÄiÄeviÄ
The simulation of strongly correlated electron systems remains a formidable challenge. Certain experimentally relevant dynamical response functions are especially difficult to calc…

Magnons in multiorbital Hubbard models, from Lieb to kagome
Teng-Fei Ying, Hugo U. R. Strand, Benjamin T. Zhou +1
We investigate the magnetic orders and excitations in a half-filled Hubbard model that continuously interpolates between the Lieb and kagome lattices. Using self-consistent Hartree…

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…
