Ming worked on an invited perspective on nematicity in the iron-based superconductors with Anna Böhmer, Jiun-Haw Chu, and Sam Lederer. The final print has appeared in Nature Physics: https://www.nature.com/articles/s41567-022-01833-3
Paper reporting discovery of charge density wave in kagome metal FeGe in collaboration with Pengcheng Dai’s group has appeared in Nature today: https://www.nature.com/articles/s41586-022-05034-z Here is the news release published by Rice: https://news.rice.edu/news/2022/interwoven-charge-and-magnetism-intertwine-kagome-material Congrats to Xiaokun and Ji Seop and everyone
We welcome Zheng Ren as a junior fellow in the Rice Academy of Fellows program to join our group!
We had four people passing their 3rd year candidacy exams this past term. Congrats to all!
A great way to end the semester, we congratulate the following folks on their achievements this past year! Yucheng won the Chuoke Award as the third year PhD student! Ben and Trey (both freshman) won the SURF fellowship to work
Nonsymmorphic symmetry-protected band crossings in a square-net metal PtPb4 Topological semimetals with symmetry-protected band crossings have emerged as a rich landscape to explore intriguing electronic phenomena. Nonsymmorphic symmetries in particular have been shown to play an important role in protecting
Our work reporting electronic reconstruction due to orbital-selective correlation effects in Fe(Te,Se) has appeared in Communications Physics. Congrats to Jianwei for leading this nice work! We also thank all of our collaborators. https://www.nature.com/articles/s42005-022-00805-6
Our paper reporting a room-temperature topological phase transition in quasi-1D Bi4I4 is to appear in PRX. The preprint is on arXiv: https://arxiv.org/abs/2105.13516 The published version can be found here: https://journals.aps.org/prx/abstract/10.1103/PhysRevX.11.031042
Our paper on flat-band itinerant ferromagnetism in RbCo2Se2 is published in PRB: https://journals.aps.org/prb/pdf/10.1103/PhysRevB.103.165105 RbCo2Se2 is isostructural to the intercalated high Tc iron-based superconductor RbFe2Se2. Via a combined ARPES, neutron, transport, and DFT study, we identify the origin of the ferromagnetic
A number of us attended the virtual March Meeting this year. Ming gave an invited talk on nematicity and orbital-selective correlations in iron-based superconductors; Jianwei (postdoc) gave a talk on our work on topological phase transition in quasi-1d materials; Han
