Cavity Nonlinear Optics at Low Photon Numbers from Collective Atomic Motion
Subhadeep Gupta, Kevin L. Moore, Kater W. Murch +1
We report on Kerr nonlinearity and dispersive optical bistability of a Fabry-Perot optical resonator due to the displacement of ultracold atoms trapped within. In the driven resona…
Observation of quantum-measurement backaction with an ultracold atomic gas
Kater W. Murch, Kevin L. Moore, Subhadeep Gupta +1
Current research on micro-mechanical resonators strives for quantum-limited detection of the motion of macroscopic objects. Prerequisite to this goal is the observation of measurem…
Probing the quantum state of a guided atom laser pulse
Kevin L. Moore, Subhadeep Gupta, Kater W. Murch +1
We describe bichromatic superradiant pump-probe spectroscopy as a tomographic probe of the Wigner function of a dispersing particle beam. We employed this technique to characterize…
Bose-Einstein condensation in a circular waveguide
S. Gupta, K. W. Murch, K. L. Moore +2
We have produced Bose-Einstein condensates in a ring-shaped magnetic waveguide. The few-millimeter diameter non-zero bias ring is formed from a time-averaged quadrupole ring. Conde…
Collimated, single-pass atom source from a pulsed alkali metal dispenser for laser-cooling experiments
Kevin L. Moore, Thomas P. Purdy, Kater W. Murch +3
We have developed an improved scheme for loading atoms into a magneto-optical trap (MOT) from a directed alkali metal dispenser in < 10^-10 torr ultra-high vacuum conditions. A cur…
