Events During the Week of March 20th through March 27th, 2011
Monday, March 21st, 2011
- Plasma Physics (Physics/ECE/NE 922) Seminar
- Separation of energy and particle transport barriers in the I-Mode regime on Alcator C-Mod
- Time: 12:05 pm
- Place: 2241 Chamberlin Hall
- Speaker: Amanda Hubbard, MIT
Tuesday, March 22nd, 2011
- Atomic Seminar
- Laser cooling and trapping of dysprosium
- Time: 10:00 am
- Place: 5310 Chamberlin
- Speaker: Seo Ho Youn, University of Illinois at Urbana-Champaign
- Abstract: I present details of the dysprosium (Dy) laser cooling and trapping apparatus at the University of Illinois at Urbana-Champaign that has recently produced a magneto-optically and magneto-statically trapped Dy gas. I also discuss unique MOT/MT dynamics and anisotropic sub-Doppler laser cooling of Dy. At the end of the talk, I conclude with a current status of Dy experiment and a prospect toward quantum degeneracy.

- Cosmology without Cosmic Variance
- Time: 4:00 pm
- Place: 2241 Chamberlin Hall (coffee at 3:30 pm)
- Speaker: Gary Bernstein, University of Pennsylvania
- Abstract: The acceleration of the Hubble expansion may be due to the failure of General Relativity to explain gravity on cosmological scales. This can be tested by measuring the gravitational growth of the largest structures, 100 Mpc or larger. The standard methods for such experiments involve measuring power spectra at different epochs, and are therefore limited by fluctuations from the finite number of large-scale modes in the observable Universe, a.k.a. "cosmic variance." I will describe how galaxy redshift and weak gravitational lensing surveys can be combined in a new way to measure gravitational growth to theoretically unlimited precision with a finite survey of the sky.
