Engineering axion insulator phase in superlattices with inversion symmetry breaking
Rajibul Islam, Sougata Mardanya, Alexander Lau +6
We study theoretically the interplay between magnetism and topology in three-dimensional HgTe/MnTe superlattices stacked along the (001) axis. Our results show the evolution of the…
Testing the data framework for an AI algorithm in preparation for high data rate X-ray facilities
Hongwei Chen, Sathya R. Chitturi, Rajan Plumley +22
The advent of next-generation X-ray free electron lasers will be capable of delivering X-rays at a repetition rate approaching 1 MHz continuously. This will require the development…
Observation of Gapped Topological Surface States and Isolated Surface Resonances in PdTe Ultrathin Films
Jacob Cook, Sougata Mardanya, Qiangsheng Lu +7
The superconductor PdTe is known to host bulk Dirac bands and topological surface states. The coexistence of superconductivity and topological surface states makes PdTe a p…
Evidence for electronic signature of magnetic transition in topological magnet HoSbTe
Nana Shumiya, Jia-Xin Yin, Guoqing Chang +11
Topological insulators with intrinsic magnetic order are emerging as an exciting platform to realize fundamentally new excitations from topological quantum states of matter. To stu…
Magnetically tunable Dirac and Weyl fermions in the Zintl materials family
Anan Bari Sarkar, Sougata Mardanya, Shin-Ming Huang +7
Recent classification efforts encompassing crystalline symmetries have revealed rich possibilities for solid-state systems to support a tapestry of exotic topological states. Howev…
Discovery of charge order and corresponding edge state in kagome magnet FeGe
Jia-Xin Yin, Yu-Xiao Jiang, Xiaokun Teng +21
Kagome materials often host exotic quantum phases, including spin liquids, Chern gap, charge order, and superconductivity. Existing scanning microscopy studies of the kagome charge…
