Events During the Week of April 18th through April 25th, 2021
Monday, April 19th, 2021
- Plasma Physics (Physics/ECE/NE 922) Seminar
- Powering the Future: Fusion & Plasmas, the FESAC Long Range Planning Report
- Time: 12:00 pm
- Place: Zoom Meeting
- Speaker: Prof. Troy Carter, UCLA
- Abstract: A long-range plan has been created to accelerate the development of fusion energy and advance plasma science. This plan is based on substantial input from the research community, which conveyed a wealth of creative ideas and its passion to accelerate fusion energy development and advance plasma science over an intensive two-year process. The FESAC Long Range Planning Report provides a decade-long vision for the field of fusion energy and plasma science, presenting a path to a promising future of new scientific discoveries, industrial applications, and ultimately the timely delivery of fusion energy.

- The Chemical Quandaries of Titan’s Atmosphere (and How We Can Solve Them)
- Time: 12:00 pm
- Place: https://uwmadison.zoom.us/j/96822123897?pwd=Z0ZESm1CNFRkUTVEMEIxM2RuN3h0UT09
- Speaker: Erin Flowers, Princeton University
- Abstract: Titan, Saturn’s largest moon, has one of the most robust atmospheres of any terrestrial body in the solar system. Its very existence came as a surprise Gerard Kuiper when he first detected it in 1944. Since then various studies, most famously the Cassini-Huygens mission, have worked to characterize this atmosphere - its formation, physical properties, and chemical composition. These studies have revealed several anomalies that have yet to be solved, such as the detached haze layers, a mysterious over abundance of molecular hydrogen, and an even more confounding downward flow of molecular hydrogen towards its surface. I’ll be discussing some of the channels I’m pursuing to try to explain these anomalies, and what it can indicate if none of them are correct.

- Physics ∩ ML Seminar
- Machine Learning for Calabi-Yau metrics
- Time: 11:00 am
- Place: Online Seminar: Please sign up for our mailing list at www.physicsmeetsml.org for zoom link
- Speaker: Fabian Ruehle, CERN and Oxford
- Abstract: String theory is a very promising candidate for a fundamental theory of our universe. An interesting prediction of string theory is that spacetime is ten-dimensional. Since we only observe four spacetime dimensions, the extra six dimensions are small and compact, thus evading detection. These extra six-dimensional spaces, known as Calabi-Yau spaces, are very special and elusive. They come with a specific type of metric needed to make string theory consistent. While we know, thanks to the heroic work of Calabi and Yau, that this metric exists, we neither know what it looks like nor how to construct it explicitly. Thinking of the metric as a function that satisfies three constraints entering the Calabi-Yau theorem, we can parameterize the metric as a neural network and formulate the problem as multiple continuous optimization tasks. I will show that this allows us to approximate Calabi-Yau metrics to very high accuracy, which will have important applications in Physics and Mathematics.

- "Simulating Galaxy Formation"
- Time: 3:30 pm
- Place: Zoom meeting(see Abstract ) Coffee and tea 3:30pm, Talk 3:45pm
- Speaker: Mark Vogelsberger, MIT
- Abstract: Cosmological simulations of galaxy formation have evolved significantly over the last years. In my talk I will describe recent efforts to model the large-scale distribution of galaxies with cosmological hydrodynamics simulations. I will focus on large-scale simulations like IllustrisTNG. After demonstrating the success of these simulations in terms of
reproducing an enormous amount of observational data, I will also talk about their limitations and directions for further improvements over the next couple of years.
