- No events scheduled
Tuesday, July 29th, 2025
- Wisconsin Quantum Institute
- Quantum Coffee Hour
- Time: 3:00 pm - 4:00 pm
- Place: Rm.5294, Chamberlin Hall
- Abstract: Please join us for the WQI Quantum Coffee today at 3PM in the Physics Faculty Lounge (Rm.5294 in Chamberlin Hall). This series, which takes place approximately every other Tuesday, aims to foster a casual and collaborative atmosphere where faculty, post-docs, students, and anyone with an interest in quantum information sciences can come together. There will be coffee and treats.
Wednesday, July 30th, 2025
- Social Gathering
- Summer Recess
- Time: 12:30 pm - 1:00 pm
- Place: Bascom Hall in front of Birge Hall
- Speaker: Everyone is welcome
- Abstract: If the weather is nice, we'll meet on Bascom Hill (in front of Birge Hall). Feel free to bring your lunch. We will borrow cornhole and ladder toss from the L&S Dean's Office and play outside for 30 minutes. Some of us will probably walk up together, meeting in the courtyard between Chamberlin and Sterling ~12:25. Feel free to walk with us! No need to sign up. Just come join us!

Thursday, July 31st, 2025
- R. G. Herb Condensed Matter Seminar
- Microwave Control of Rydberg-Rydberg Interactions
- Time: 10:00 am - 11:00 am
- Place: 5310 Chamberlin
- Speaker: Deniz Kurdiak, University of Maryland
- Abstract: Experimental control over the strength and angular dependence of interactions between atoms is a key capability for advancing quantum technologies. Here, we use microwave dressing to manipulate Rydberg-Rydberg interactions in an atomic ensemble. By coupling opposite parity Rydberg states, we create eigenstates with first-order dipole-dipole interactions. We study the modification of the interactions by measuring the statistics of the light retrieved from the ensemble. Furthermore, we discuss the prospects for the nullification of the interactions and the generation of bound states. These more ambitious interaction engineering proposals require precise control over the polarization of the microwave fields, which is a challenge for many atomic physics experiments. We develop spectroscopic techniques to measure the polarization of microwave fields and utilize multiple sources with independent phase and amplitude control to generate arbitrary microwave polarizations.
