Author(s): D. M. Broun, H. U. Özdemir, Vivek Mishra, N. R. Lee-Hone, Xiangru Kong, T. Berlijn, and P. J. HirschfeldDopant impurity potentials determined by ab initio supercell density functional theory calculations are used to calculate the optical conductivity of overdoped La2−xSrxCuO4 (LSCO) and Tl2Ba2CuO6+δ (Tl-2201) in the superconducting and normal...
Author(s): Feng Xue, Jiaheng Li, Yizhou Liu, Ruqian Wu, Yong Xu, and Wenhui DuanTopological and valleytronic materials are promising for spintronic and quantum applications due to their unique properties. Using first principles calculations, we demonstrate that germanene (Ge)-based ferromagnetic heterostructures can exhibit multiple quantum states such...
Author(s): Andor Menczer, Kornél Kapás, Miklós Antal Werner, and Örs LegezaWe present a hybrid numerical approach to simulate quantum many-body problems on two spatial dimensional quantum lattice models via the non-Abelian ab initio version of the density matrix renormalization group method on state-of-the-art high-performance computing infrastructures....
Author(s): Verena Brehm, Pawel Sobieszczyk, Jostein N. Kløgetvedt, Richard F. L. Evans, Elton J. G. Santos, and Alireza QaiumzadehThe microscopic origin of the topological magnon band gap in CrI3 ferromagnets has been a subject of controversy for years since two main models with distinct characteristics, i.e., Dzyaloshinskii-Moriya (DM) and Kitaev,...
Author(s): Mohammad Balal, Shuvam Sarkar, Pramod Bhakuni, Andrei Gloskovskii, Aparna Chakrabarti, and Sudipta Roy BarmanCollective plasmon excitations in solids that result from the process of photoemission are an important area of fundamental research. In this study, we identify a significant number (n) of multiple bulk plasmons (nωp) in the hard x-ray...
Author(s): Hongshuang Liu, Jin Cao, Zeying Zhang, Jiashuo Liang, Liying Wang, and Shengyuan A. YangRealizing ideal Weyl semimetal state with a single pair of Weyl points has been a long-sought goal in the field of topological semimetals. Here, we reveal such a state in the Cr-based half-Heusler compounds XCrTe (X=K, Rb). We show that these materials...
