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…
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…
Nearly triple nodal point topological phase in half-metallic GdN
Jinwoong Kim, Heung-Sik Kim, David Vanderbilt
Recent developments in topological semimetals open a way to realize relativistic dispersions in condensed matter systems. One recently studied type of topological feature is the "t…
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…
Nodal-chain network, intersecting nodal rings and triple points coexisting in nonsymmorphic Ba3Si4
Jin Cai, Yuee Xie, Po-Yao Chang +2
Coexistence of topological elements in a topological metal/semimetal (TM) has gradually attracted attentions. However, the non-topological factors always mess up the Fermi surface…
