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
Congratulations to Jianwei for winning an APS Division of Materials Physics Post-Doctoral Travel Award to present his work on quasi-1d topological insulators at the March Meeting!
Our paper on nematicity in FeSe is published in PRX: https://journals.aps.org/prx/abstract/10.1103/PhysRevX.9.041049 It is also covered by Rice news release: http://news.rice.edu/2019/12/06/electronic-map-reveals-rules-of-the-road-in-superconductor-2/ In this paper, we report very detailed and fine measurement of the band structure reconstruction in the nematic phase of
