Non-partisan voting information session
Time: 1:30 pm - 3:00 pm
Place: Zoom:
Speaker: Susan Nossal
Abstract: Greetings everyone,

You are invited to an informal discussion about non-partisan voting information on Tuesday, August 2nd at 1:30 PM via Zoom, in advance of the Tuesday, August 9th, Wisconsin primary election. We will talk about where to find information about topics such as eligibility, voter registration, voter ID, early in-person absentee voting, and returning absentee ballots. We also will discuss how to find out what is on your ballot, as well as some ways to research positions of candidates. A few resources for non-partisan voting information are the UW voter information site, the Wisconsin MyVote site, and the League of Women Voters Dane County.

This will be an opportunity for us all to share information with each other. If we don’t know the answers, we will try to point people to places where they may be able to get their questions addressed. If possible, it may be helpful to log on with a device that you can use to access various websites.

Early in-person absentee voting has begin in Madison, including on the UW-Madison campus.

Everyone is welcome! Even if you are not eligible to vote, but you would like to learn more about the voting process in Wisconsin, please come.

We look forward to seeing you!

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!

APS Chapters Virtual Seminar
Time: 2:00 pm - 3:00 pm
Place: Chamberlin 4274
Speaker: Marciano Bagnoli
Abstract: Marciano Bagnoli will be joining us via zoom to talk about his experience in industry. Marciano is a scientist and manager at Bakelite Synthetics where he oversees and implements continuous improvement projects throughout the global organization. He has previously localized cosmetic and thermal-interface material production lines from Japan to the United States. Marciano has also served as a consultant to help small businesses in Germany access international projects throughout the European Union, and award grants to innovative start-up companies. In addition, he designs, equips, and staffs laboratories to ensure the products produced meet strict domestic and international quality standards.
Coffee and snacks will be provided to those joining in person!

Thesis Defense
Nanophotonic Systems for Novel Applications: From Spaceflight to Self-Assembled Materials to Thermal Radiation
Time: 1:00 pm - 3:00 pm
Place: 4274 Chamberlin Hall or
Speaker: Joel Siegel, Physics PhD Graduate Student
Abstract: "The optical properties of a material can be altered by structuring the material with features on the order of the wavelength of interest. This patterning allows for materials to be designed with a targeted optical property, which can be used for any number of potential applications. The focus of this dissertation is a discussion on how the same fundamental principles of light manipulation can be applied to multiple distinct objectives, ranging from interstellar to the nanoscale. In the first section of the dissertation, there will be a discussion on how the microscopic optical forces exerted on a metasurface lightsail propelled by a high-power laser can be engineered via its optical properties to achieve passive self-stabilization, such that the sail is trapped inside the drive beam. In the second section of this dissertation, there will be a discussion on development of a large-scale nanofabrication technique of narrow (< 15 nm) graphene resonators based on block copolymer lithography and how the characteristic scaling laws of resonant graphene plasmons change for these narrow resonators. Additionally, there is a discussion on some potential avenues towards incorporating these into more complex optical designs. In the final section of the dissertation, a method to electronically change the angle of thermal emission from a device based on graphene is discussed."

Thesis Defense
Improving the performance of quantum computing with neutral atoms
Time: 10:00 am - 12:00 pm
Place: Chamberlin 4274
Speaker: Xiaoyu Jiang , Physics PhD Graduate Student
Abstract: This thesis reports progress towards implementing quantum computing applications on a 2-dimensional array of neutral atom qubits. While numerous progress has taken place in our lab, here we focus on presenting theoretical analysis on various aspects of the experiment, to help improve the performance of the main experiment.

We finished a thorough analysis on the effect of laser noise on 1- and 2-photon Rabi oscillations, with both theoretical analysis and numerical simulations. We developed a theory to directly match a laser's frequency noise power spectral density to its self-heterodyne spectrum measured in labs. We also predicted the error generated by white noise and spectrums with servo-bumps, and our results have a good match with numerical simulations. A quasi-static theory is also proposed to estimate the error under certain limits, and has demonstrated good match with the numerics.

We design a protocol for multi-qubit neutral atom gates. The protocol implements symmetric adiabatic pulses on the k+1 atoms in the system to implement CkZ gates and CZk gates. Equal Rydberg coupling strengths between all qubits are needed for CkZ gates, and zero coupling between target qubits is needed for CZk gates. We show that fidelity F &gt;0.99 can be achieved for both type of gates, with gate times ~0.5 μs for k&lt;=4. Our analysis is performed with experimentally realistic parameters.
