Investigation into the inadequacy of cRPA in reproducing screening in strongly correlated systems
Qiang Han, B. Chakrabarti, K. Haule
The accuracy of the constrained random phase approximation(cRPA) method is examined in multi-orbital Hubbard models containing all possible on-site density-density interactions. Us…
Molecular Mott state in the deficient spinel GaVS
Heung-Sik Kim, Kristjan Haule, David Vanderbilt
In this study, we investigated theoretically the Mott-insulating phase of a deficient spinel chalcogenide GaVS, which is known to form a tetrahedral VS cluster unit…
Electronic Spin transition in FeO: evidence for Fe(II) with peroxide O
Bo Gyu Jang, Jin Liu, Qingyang Hu +5
The discovery of FeO containing more oxygen than hematite (FeO) that was previously believed to be the most oxygen rich iron compounds, has important implications…
Feynman's solution of the quintessential problem in solid state physics
Kun Chen, Kristjan Haule
Two of the most influential ideas developed by Richard Feynman are the Feynman diagram technique and his variational approach. The former provides a powerful tool to construct a sy…
Mott metal-insulator transitions in pressurized layered trichalcogenides
Heung-Sik Kim, David Vanderbilt, Kristjan Haule
Transition metal phosphorous trichalcogenides, ( and being transition metal and chalcogen elements respectively), have been the focus of substantial interest r…
Trimer Bonding States on the Surface of Transition-metal Dichalcogenide TaTe2
Chen Chen, Heung-Sik Kim, Alemayehu S. Admasu +4
We report a comprehensive study on the surface structural and electronic properties of TaTe2 at room temperature. The surface structure was investigated using both low energy elect…
