- R. G. Herb Condensed Matter Seminar
- Strongly correlation and topology in Kondo lattice systems
- Time: 10:00 am - 11:00 am
- Place: 5310 Chamberlin
- Speaker: Sheng Ran, Washington University in St Louis
- Abstract: Quantum materials with both strong correlations and nontrivial band structure topology can have novel physics properties that do not exist in the non-correlated counterparts. Recent theoretical work has proposed that combination of Kondo physics and nonsymmorphic crystal symmetries can give rise to such strong correlated topological systems. In this talk, I will present our recent experimental exploration this direction. In one case, we found intrinsic anomalous Hall effect that seems to break the Fermi liquid scaling relation. In another case, we have discovered a candidate for topological Kondo insulator with high temperature metallic surface state.

- Astronomy Colloquium
- The SPHEREx Space Mission: Preliminary Results
- Time: 3:30 pm - 4:30 pm
- Place: 4421 Sterling Hall
- Speaker: Dr. Roberta Paladini, IPAC
- Abstract: The Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer (SPHEREx) is a Medium-Class Explorer (MIDEX) NASA mission launched on March 11th 2026. SPHEREx has just completed the second full sky coverage in 102 spectral bands from 0. 75 to 5 micron at 6.15" spatial resolution. In this presentation, I will provide an overview of both the technical aspects of the mission and the L1 Science requirements. I will also describe how the astronomical community at large can access the SPHEREx data and the tools that are made publicly available for their scientific exploitation. Finally, I will discuss early results from the mission.
