Physics & Astronomy Colloquium at CSU Long Beach

Searching for the Dark Universe

with Matter Wave Interferometry

Paul Hamilton
Dept. of Physics & Astronomy, UCLA

Monday, October 12, 2015
11:15am - 12:30pm in PH2-126

The interference of matter waves is often presented in textbooks as a historical demonstration cementing wave-particle duality. Far from being just a quirk of quantum mechanics, modern matter wave interferometry is a precise toolbox for atomic physicists with possible applications ranging from GPS-free navigation to detection of gravitational waves. I will discuss a new direction for the field, using atom interferometry to probe the properties of dark matter and dark energy, and focus on our recent result which used interference of laser-cooled atoms to place the first constraints on certain forms of dark energy.

All Physics students & faculty should attend!

See the colloquium schedule and its archive of previous talks

Colloquia are scheduled to start Mondays at 11:15am sharp in Peterson Hall 2, Room 126 (PH2-126). Refreshments are served from 10:45am to 11:05am in Room HSCI-224 (next to the department office) and everyone is invited to mingle with faculty and students!
