Events on Tuesday, October 8th, 2019
- R. G. Herb Condensed Matter Seminar
- Spectroscopy with Josephson Junctions
- Time: 11:00 am
- Place: 4274 Chamberlin Hall
- Speaker: Dr. Çaglar Girit, College de France
- Abstract: Spectroscopy, by providing a direct measurement of the energy spectrum, is a powerful tool to probe matter. Conventional spectroscopy techniques suffer several drawbacks when applied to mesoscopic systems, or artificial quantum coherent atoms. I present an on-chip, Josephson-junction based spectrometer which surpasses state-of-the-art instruments, works between 2-200 GHz, and is ideally suited for probing elementary excitations in mesoscopic systems. I describe the operating principle and design of the spectrometer, show spectra of several superconducting quantum circuits, and outline experiments to investigate single quasiparticles in superconductors.
- Host: Brar
- Chaos & Complex Systems Seminar
- Beer, biofuels, and beyond: yeast biodiversity in the era of genomics
- Time: 12:05 pm - 1:00 pm
- Place: 4274 Chamberlin (refreshments will be served)
- Speaker: Chris Hittinger, UW Department of Genetics
- Abstract: Here, I will present a general audience lecture on yeast biodiversity in the age of genomics. Topics will include beer, biofuels, and other fermentation products, as well as new approaches in synthetic biology.
