Spin-Triplet Topological Excitonic Insulators in Two-dimensional Materials
Huaiyuan Yang, Jiaxi Zeng, Yuelin Shao +3
Quantum spin-hall insulator (QSHI) processes nontrivial topology. We notice that the electronic structures of some particular QSHIs are favorable for realization of excitonic insul…
Phonon transition across an isotopic interface
Ning Li, Ruochen Shi, Yifei Li +13
Natural materials usually consist of isotopic mixtures, for which different isotopic ratios can lead to distinct material properties such as thermal conductivity and nucleation pro…
Non-perturbative approach for calculating the electrical conductivity of a liquid metal
Xiao-Wei Zhang, Haoran Chen, En-Ge Wang +2
We propose a non-perturbative approach to calculate the electrical conductivity of a liquid metal. Our approach is based on the Kubo formula and the theory of electro…
Phonon-mediated exciton relaxation in two-dimensional semiconductors: selection rules and relaxation pathways
Xiao-Wei Zhang, Kaichen Xie, En-Ge Wang +2
Exciton-phonon coupling (ExPC) is crucial for energy relaxation in semiconductors, yet the first-principles calculation of such coupling remains challenging, especially for low-dim…
Engineering of Atomic-Scale Flexoelectricity at Grain Boundaries
Mei Wu, Xiaowei Zhang, Xiaomei Li +9
Flexoelectricity is a type of ubiquitous and prominent electromechanical coupling, pertaining to the response of electrical polarization to mechanical strain gradients while not re…
The exciton-polariton properties of hexagonal BN based microcavity and their potential applications in BEC and superconductivity
Huaiyuan Yang, Xinqiang Wang, Xin-Zheng Li
Microcavity exciton-polaritons are two-dimensional bosonic quasiparticles composed by excitons and photons. Using model Hamiltonian with parameters generated from ab initio density…
