- Network in Neutrinos, Nuclear Astrophysics, and Symmetries (N3AS) Seminar
- Escapers, merger remnants and double-faced stars: studying exotic white dwarfs with ZTF and Gaia
- Time: 2:00 pm
- Place: Join Zoom Meeting
- Speaker: Ilaria Caiazzo , Caltech
- Abstract: The advent of Gaia and of large photometric and spectroscopic surveys is changing the landscape of white dwarf studies. These incredible new data sets, together with improved models, have enabled tackling some unsolved mysteries concerning white dwarfs as a population, as well as discovering extremely peculiar objects that challenge our understanding of white dwarf formation and evolution. In my talk, I will show how the precise astrometry from Gaia has dramatically improved our capability of studying young star clusters, and therefore probe the evolution of white dwarfs born from single progenitor stars. On the other hand, the Zwicky Transient Facility is shedding light on the evolution of white dwarfs in binary systems, substantially increasing the number of known eclipsing white dwarf binaries and finding the final products of such binaries. In fact, ZTF is discovering a large number of massive, rapidly rotating and highly magnetized white dwarfs whose extreme properties characterize them with high confidence as remnants of white-dwarf mergers. Finding a population of white dwarf merger remnants just below the Chandrasekhar mass can help constrain the number of mergers in the Galaxy and their contribution to the type Ia supernova rate, as well as help us understand the origin of strong magnetic fields in white dwarfs. I will present some early results of the search, including the discovery of extremely peculiar white dwarfs.

- Department Meeting
- Time: 12:15 pm - 1:15 pm
- Place: 5310 Chamberlin Hall
- Speaker: Mark Eriksson, UW-Physics
- NOTE LOCATION: *****5310 CHAMBERLIN*****
- Host: Mark Eriksson
- Physics Summer Fun
- Weekly Recess
- Time: 12:30 pm - 1:00 pm
- Place: Bascom Hill or 5310 Chamberlin Hall
- Speaker: Sharon Kahn
- Abstract: We hope you’ll take a 20-30 minute break on (some/all) Wednesdays this summer (12:30-1pm) to come play together! For nice days, we’ve arranged to borrow some lawn games from the L&S dean’s office and will likely bring along a frisbee and/or a hackeysack, too. Meet us on Bascom Hill (between Birge/South Hall).
In case of rain, we’ll meet indoors (5310 CH) for board games. Feel free to come play or just hang out! - Climate & Diversity
- Bystander Intervention Skills for Physics Faculty and Staff
- Time: 2:30 pm - 4:00 pm
- Place: 2223 Chamberlin
- Speaker: Tamie Klumpyan, UW Office of Human Resources
- Abstract: Have you ever witnessed something that left you uneasy or concerned for another person at work, but you didn’t know how to step in and improve the situation? You are not alone. It is common to feel unsure of what to do when we witness behavior that concerns us.
Through reflection, discussion and practice, you will explore with colleagues how you can effectively step in when concerning workplace situations arise.
• Learn - effective bystander intervention principles and practices
• Practice- assess a concerning workplace situation and identify motivations and hesitations to interrupt
• Options - consider various options to effectively interrupt negative situations through a 4D Intervention Model

- Mid-circuit correction of correlated phase errors on a dual-element atom array
- Time: 1:00 pm - 2:00 pm
- Place: 5310 Chamberlin
- Speaker: Hannes Bernien , U. Chicago
- Abstract: Scaling up invariably error-prone quantum processors is a formidable challenge. While quantum error correction ultimately promises fault-tolerant operation, the required qubit overhead and error thresholds are daunting, and many codes break down under correlated noise. Recent proposals have suggested a complementary approach based on co-located, auxiliary ‘spectator’ qubits. These act as in-situ probes of noise, and enable real-time, coherent corrections of the resulting errors on the data qubits. Here, we use an array of cesium spectator qubits to correct correlated phase errors on an array of rubidium data qubits [1]. Crucially, by combining in-sequence readouts, data processing, and feed-forward operations, these correlated errors are suppressed within the execution of the quantum circuit. In the second part of the talk, I will discuss our progress towards creating light-matter interfaces based on individual atoms coupled to nano-photonic crystal structures with the long-term vision of connecting distant atom array nodes with entanglement.
