- Chaos & Complex Systems Seminar
- urbulence, the manifestation of eddies and their role in conservation laws
- Time: 12:05 pm - 1:00 pm
- Place: 4274 Chamberlin Hall (Refreshments will be served)
- Speaker: George Hrabovsky, Madison Area Science and Technology
- Abstract: Only in technically dry fluids can you get away from the phenomena of turbulence. Such phenomena serve to transport important quantities across scales. Why is this important? Because two thirds of the classical states of matter are composed of fluids. Fluids exist on most scales of distance measurement—some surprising. Where there are non-perfect fluids, there is turbulence. Why is the transport of these quantities across scales important? What are the ramifications for physical and predictive modeling? Come to the talk and find out...<br>
- Host: Sprott
- Theory Seminar (High Energy/Cosmology)
- Condensed Dark Matter: An Axion Story
- Time: 3:30 pm - 4:30 pm
- Place: 5280 Chamberlin Hall
- Speaker: Chanda Prescod-Weinstein, MIT
- Abstract: Recently there has been significant interest in the claim that axions, a popular dark matter candidate, form a Bose-Einstein condensate on a scale that has consequences for structure formation. I will describe my work examining this claim. It is clear that while Bose-Einstein condensates of axions form, they don't have the structure that was initially expected. Yet again, it matters whether particles are attracted or repulsed by one another.
