The dynamics of quantum states of light propagating through slow-light media have been well- characterized both theoretically and experimentally. The question

We present experimental observations of coherent spin-population oscillations in a cold thermal, Bose gas of spin-1 23Na atoms. The population oscillations in a
Alberto M. Marino, Neil V. Corzo Trejo, Paul D. Lett
We study the effect of losses on the phase sensitivity of the SU(1,1) interferometer for different configurations. We find that this type of interferometer is
We report on the four-wave mixing of superluminal pulses, in which both the injected and generated pulses involved in the process propagate with negative group

The transit times of photons traveling through opaque barriers such as dielectric stacks exhibit the Hartman saturation effect. This saturation of the transit

We present experimental results showing that quantum correlated light can be produced using non-degenerate, off-resonant, four-wave mixing (4WM) on both the D1

We present an experimental realization of a low-noise, universal, phase-insensitive optical amplifier using four-wave mixing interaction in hot Rb vapor

We characterize fluctuations in atom number and spin populations in F = 1 sodium spinor condensates. The time evolution of the population fluctuations shows a

Spinor Bose-Einstein condensates of F=1 sodium atoms display interesting spin population dynamics due to the antiferromagnetic nature of the interactions in
Vincent Boyer, Alberto M. Marino, Raphael C. Pooser, Paul D. Lett
The entanglement properties of two beams of light can reside in subtle correlations that exist in the unavoidable quantum fluctuations of the amplitudes and the
Alberto M. Marino, Vincent Boyer, Raphael C. Pooser, Paul D. Lett
One of the most important resources in quantum mechanics is entanglement, which is characterized by correlations stronger than the ones allowed classically. As

We report a prediction for the delay measured in an optical tunneling experiment using HongOuMandel (HOM) interference, taking into account the Goos-H¨anchen

We generate intensity-difference-squeezed Laguerre-Gauss twin beams carrying orbital angular momentum using 4-wave mixing (4WM) in a hot atomic vapor. The
Vincent Boyer, Alberto M. Marino, Raphael C. Pooser, Paul D. Lett
Two beams of light can be quantum mechanically entangled through correlations of their phase and intensity fluctuations. For a pair of spatially extended image
We have observed a violation of the Cauchy-Schwarz inequality in the macroscopic regime by more than 8 standard deviations. The violation has been obtained
We have observed the ultraslow propagation of matched pulses in nondegenerate four-wave mixing in a hot atomic vapor. Probe pulses as short as 70 ns can be
A T. Black, Eduardo Gomez, Lincoln Turner, Sebastian Jung, Paul D. Lett
We observed coherent spin oscillations in an antiferromagnetic spin-1 Bose-Einstein condensate of sodium. The variation of the spin oscillations with magnetic

We study the time-resolved photoassociation of ultracold sodium in an optical dipole trap. The photoassociation laser excites pairs of atoms to molecular states
Kevin Jones, Eite Tiesinga, Paul D. Lett, Paul S. Julienne
Photoassociation is the process where two colliding atoms absorb a photon to form an excited molecule. The development of laser cooling techniques for producing

We demonsatrate an all optical technique to evaporatively produce sodium Bose-Einsteincondensates (BEC). We use a crossed-dipole trap formed from light near 1 $
