11. Collective atom counting and first lasing on a millihertz linewidth optical transition

Prof. James Thompson (JILA, Dept. of Physics, NIST, University of Colorado)

2/22/16, 3:00 PM

Invited talk

Is it possible to exploit atom-atom correlations and entanglement to advance the field of precision measurement beyond the current independent-atom paradigm? We have explored this question along two fronts that will be discussed: superradiant or bad-cavity lasers that could be 10,000 times less sensitive to thermal motion of the optical cavity’s mirrors [1], and spin-squeezed states that can...

38. Cooperative transmission in an optically dense medium on the strontium intercombination line

Dr david wilkowski (ntu-cqt-majulab)

2/22/16, 3:30 PM

Invited talk

The coherent transmission of a wave, through scattering medium, results of interference between the incident field and the forward scattering field. This basic and well established process was experimentally observed in the case of an electromagnetic wave transmitted through a resonant strontium cold cloud [1]. Since the forward scattering field is build up on the incident field, one may state...
