Elusive Exciton Insulator States in 1T-HfTe2: Exciton softening, and Symmetry Breaking by Ab Initio Methods
Hong Tang, Niraj Pangeni, Daniel D. Rivera +1
Recent experiments have provided evidence for excitonic insulator (EI) states in 1T HfTe2. In this work, we investigate EI states in monolayer, bilayer, trilayer, and bulk 1T HfTe2…

Diverse edge states of nanoribbons and excitonic insulator states of the monolayer Ta2Ni3Te5
Hong Tang, Jiang Wei, Gabor I. Csonka +1
Ta2Ni3Te5, a layered transition metal chalcogenide with quasi-one-dimensional electronic states, exhibits rich topological and correlated phenomena. Using first-principles calculat…
