Correlations in Amplified Four-Wave Mixing of Matter Waves

Abstract

The coherence properties of amplified matter waves generated by four-wave mixing (FWM) are studied using the Hanbury-Brown-Twiss method. We examine two limits. In the first case stimulated processes lead to the selective excitation of a pair of spatially separated modes, which we show to be second order coherent, while the second occurs when the FWM process is multimode, due to spontaneous scattering events which leads to incoherent matter waves. Amplified FWM is a promising candidate for fundamental tests of quantum mechanics where correlated modes with large occupations are required.

Using Correlation Measurements to Probe Amplified Matter Waves and Bose-Einstein Condensate Formation

RuGway Wu, Sean S. Hodgman, Andrew Manning +3 more

Using single atom detection offered by metastable helium atoms (He*), we are able to measure correlations between atoms. With this we have demonstrated second-order coherence of matter waves that emerge from amplified four-wave mixing (FWM). Our results provide the first second-order, or quantum test of coherence for amplified matter waves. Using the same detection scheme, we have investigated the onset of coherence during the formation of a Bose-Einstein condensate (BEC), attempting to reveal how the long-range order of a BEC is established. Our initial results support the existence of quasi-condensates.

Does Matter Wave Amplification Work for Fermions?

Wolfgang Ketterle, S. Inouye

We discuss the relationship between bosonic stimulation, density fluctuations, and matter wave gratings. It is shown that enhanced stimulated scattering, matter wave amplification, and atomic four-wave mixing do not require macroscopic occupation of a single quantum state. These processes are in principle possible for fermionic or nondegenerate samples, if they are prepared in a cooperative state. In practice, there are limitations due to short coherence times.

Intensity instability and correlation in amplified multimode wave mixing

Haechan An, Hal Owens, Hamza Ather +2 more

The dynamics of optical nonlinearity in the presence of gain and feedback can be complex leading to chaos in certain regimes. Temporal, spectral, spatial, or polarization instability of optical fields can emerge from chaotic response of an optical [Formula: see text] or [Formula: see text] nonlinear medium placed between two cavity mirrors or before a single feedback mirror. The complex mode dynamics, high-order correlations, and transition to instability in these systems are not well known. We consider a [Formula: see text] medium with amplified four-wave mixing process and study noise and correlation between multiple optical modes. Although individual modes show intensity instability, we observe relative intensity noise reduction close to the standard quantum noise, limited by the camera speed. We observe a relative noise reduction of more than 20 dB and fourth-order intensity correlation between four spatial modes. More than 100 distinct correlated quadruple modes can be generated using this process.

Atom-atom correlations in spontaneous four wave mixing of two colliding Bose-Einstein Condensates

A. Perrin, Hong Chang, Valentina Krachmalnicoff +4 more

We study atom scattering from two colliding Bose-Einstein condensates using a position sensitive, time resolved, single atom detector. In analogy to quantum optics, the process can also be thought of as spontaneous, degenerate four wave mixing of de Broglie waves. We find a clear correlation between atoms with opposite momenta, demonstrating pair production in the scattering process. We also observe a Hanbury Brown and Twiss correlation for collinear momenta, which permits an independent measurement of the size of the pair production source and thus the size of the spatial mode. The back to back pairs occupy very nearly two oppositely directed spatial modes, a promising feature for future quantum optics experiments.

The Hanbury Brown Twiss effect for atomic matter waves

Christoph Ira Westbrook, Denis Boiron

This paper discusses our recent work on developing the matter wave analogs to the Hanbury Brown Twiss experiment. We discuss experiments using cold atoms, both bosons and fermions, both coherent and incoherent. Simple concepts from classical and quantum optics suffice to understand most of the results, but the ideas can also be traced back to the work of Einstein on the thermodynamics of Bose gases.

Coherence properties of amplified slow light by four-wave mixing

Ya-Fen Hsiao, Pin-Ju Tsai, Chi-Ching Lin +3 more

We present an experimental study of the coherence properties of amplified slow light by four-wave mixing (FWM) in a three-level electromagnetically induced transparency (EIT) system driven by one additional pump field. High energy gain (up to 19) is obtained with a weak pump field (a few mW/cm2) using optically dense cold atomic gases. A large fraction of the amplified light is found to be phase incoherent to the input signal field. The dependence of the incoherent fraction on pump field intensity and detuning and the control field intensity is systematically studied. With the classical input pulses, our results support a recent theoretical study by Lauk et al. [Phys. Rev. A88, 013823 (2013)], showing that the noise resulting from the atomic dipole fluctuations associated with spontaneous decay is significant in the high gain regime. This effect has to be taken into consideration in EIT-based applications in the presence of FWM.
