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…
Unusual Electron-Phonon Interactions in Highly Anisotropic Two-Dimensional
Fei Wang, Qiaohui Zhou, Hong Tang +9
Electron-phonon interactions (EPIs) represent a fundamental cornerstone of condensed matter physics, commanding persistent attention due to their pivotal role in driving novel quan…
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…
A meta-generalized gradient approximation-based time-dependent and dielectric function dependent method for optical properties of solid materials
Hong Tang, Niraj Pangeni, Adrienn Ruzsinszky
Accurate and efficient calculation of optical response properties of solid materials is still challenging. We present a meta-generalized gradient approximation (metaGGA) density fu…
Inside the Working Mechanism of Meta-generalized Gradient Density Functional Approximations: The Example of Quantum Spin-Hall Insulator 1T`-WTe2
Li Yin, Hong Tang, Adrienn Ruzsinszky
Quantum spin Hall (QSH) insulators have attracted intensive experimental and theoretical studies due to their beneficial applications in spintronic devices. Density functional theo…
A Pathway to Efficient Simulations of Charge Density Waves in Transition Metal Dichalcogenides: A Case Study for TiSe2
Li Yin, Hong Tang, Tom Berlijn +1
Charge density waves (CDWs) in transition metal dichalcogenides are the subject of growing scientific interest due to their rich interplay with exotic phases of matter and their po…
