Wisconsin Quantum Institute
Quantum Information Science (QIS) Career Fair
Time: 10:00 am - 4:00 pm
Place: Virtual, learn more and register at
Speaker: various, U.S. Department of Energy Office of Science
Abstract: The Quantum Information Science Career Fair, sponsored by the U.S. Department of Energy's Office of Science's National Quantum Information Science (QIS) Research Centers, aims to bring awareness to two- and four-year college and graduate students and post-doc to the wide range of QIS careers they can pursue—from technical and scientific roles to non-STEM roles that facilitate research and bring awareness to the field, like marketing and human resources.

Participants will hear from experts in their field, get their questions answered, build their professional networks, and meet one-on-one with potential employers. The event will showcase opportunities available within the Centers, national laboratories, academic institutions, and industry.

This QIS Career Fair is a public event and sessions will be recorded. All participants must register online by September 14, 2022 to attend. Please contact the Career Fair Coordinator with questions.

Theory Seminar (High Energy/Cosmology)
The BOSS bispectrum analysis at one loop from the Effective Field Theory of Large-Scale Structure
Time: 4:00 pm
Place: Chamberlin 5280
Speaker: Matthew Lewandowski, Northwestern U.
Abstract: In this talk, I will discuss our recent analysis of the BOSS power spectrum monopole and quadrupole, and the bispectrum monopole and quadrupole data, using the predictions from the Effective Field Theory of Large-Scale Structure (EFTofLSS). Specifically, we use the one-loop prediction for the power spectrum and the bispectrum monopole, and the tree level for the bispectrum quadrupole. After validating our pipeline against numerical simulations as well as checking for several internal consistencies, we apply it to the observational data. We find that analyzing the bispectrum monopole to higher wavenumbers thanks to the one-loop prediction, as well as the addition of the tree-level quadrupole, significantly reduces the error bars with respect to our original analysis of the power spectrum at one loop and bispectrum monopole at tree level. We find significant error bar reduction with respect to the power spectrum-only analysis. Remarkably, the results are compatible with the ones obtained with a power-spectrum-only analysis, showing the power of the EFTofLSS in simultaneously predicting several observables. We find no tension with Planck.
