Nonclassicality generated by photon annihilation-then-creation and creation-then-annihilation operations (2009)

Lee, Su-Yong, Park, Jiyong, Ji, Se-Wan, Ooi, C. H. Raymond, Lee, Hai-Woong

We examine nonclassical properties of the field states generated by applying the photon annihilation-then-creation operation (AC) and creation-then-annihilation operation (CA) to the thermal and...

Connection between Wigner distribution of nonclassical fields and collapse-revival of atomic dynamics (2008)

Ooi, C. H. Raymond

The transient evolution of nonclassical radiation fields interacting with an atom in a cavity is correlated to the atomic dynamics. Connection between the atomic phases of collapse and revival, and...

Controlling Irreversibility and Directional Flow of Light with Atomic Motion (2008)

Ooi, C. H. Raymond

The Doppler effect of moving atoms can create irreversibility of light. We show that the laser field in electromagnetic induced transparency (EIT) scheme with atomic motion can control the...

Effects of Chirped Laser Pulses on Nonclassical Correlation and Entanglement of Photon Pairs from Single Atom (2008)

Ooi, C. H. Raymond

We study the effects of arbitrary laser pulse excitations on quantum correlation, entanglement and the role of quantum noise. The transient quantities are computed exactly using a method that...

Coherent effects on two-photon correlation and directional emission of two two-level atoms (2007)

Ooi, C. H. Raymond, Kim, Byung-Gyu, Lee, Hai-Woong

©2007 The American Physical Society URL: http://link.aps.org/abstract/PRA/v75/e063801 doi:10.1103/PhysRevA.75.063801 PACS: 42.50.Fx, 42.50.Ar, 03.67.Mn

Phase Controlled Continuously Entangled Two-Photon Laser with Double $\Lambda$ Scheme (2007)

Ooi, C. H. Raymond

We show that an absolute coherent phase of a laser can be used to manipulate the entanglement of photon pairs of two-photon laser. Our focus is on the generation of a continuous source of entangled...

Fluctuation statistics of mesoscopic Bose-Einstein condensate: reconciling the master equation with the partition function to revisit the Uhlenbeck-Einstein dilemma (2006)

Jordan, Andrew N., Ooi, C. H. Raymond, Svidzinsky, Anatoly A.

The atom fluctuations statistics of an ideal, mesoscopic, Bose-Einstein condensate is investigated from several different perspectives. By generalizing the grand canonical analysis (applied to the...

Fluctuations in Ideal and Interacting Bose-Einstein Condensates: From the laser phase transition analogy to squeezed states and Bogoliubov quasiparticles (2006)

Kocharovsky, Vitaly V., Kocharovsky, Vladimir V., Holthaus, Martin, Ooi, C. H. Raymond, Svidzinsky, Anatoly A., Ketterle, Wolfgang, ...

We review the phenomenon of equilibrium fluctuations in the number of condensed atoms in a trap containing N atoms total. We start with a history of the Bose-Einstein distribution, the...

Rotational Cooling of Polar Molecules by Stark-tuned Cavity Resonance (2003)

Ooi, C. H. Raymond

A general scheme for rotational cooling of diatomic heteronuclear molecules is proposed. It uses a superconducting microwave cavity to enhance the spontaneous decay via Purcell effect. Rotational...

A New Laser Cooling Concept for Molecular Translational Motion (2001)

Ooi, C. H. Raymond, Marzlin, Kar Peter, Audretsch, Juergen

We propose a laser cooling concept for the translational motion of molecules which does not require repeated spontaneous emission by each molecule. The cooling works by repetition of three main...
