UNC Physics Colloquium

“Clock, quantum matter, and fundamental physics”

Precise control of quantum states of matter and innovative laser technology are revolutionizing the performance of atomic clocks and metrology. Sr atoms cooled to a degenerate quantum gas and loaded into arrays of optical traps highlights new measurement capabilities building on the exploration of quantum and precision physics. This increasingly powerful physics frontier is promising greater opportunities for probing fundamental and emerging phenomena. I will highlight recent work where the gravitation red shift within a single atomic ensemble is measured at the 1 x 10^-20 level.
