Dynamical evolution of correlated spontaneous emission of a single photon from a uniformly excited cloud of N atoms (2008)

Svidzinsky, Anatoly A., Chang, Jun-Tao, Scully, Marlan O.

We study the correlated spontaneous emission from a dense spherical cloud of N atoms uniformly excited by absorption of a single photon. We find that the decay of such a state depends on the relation...

Cooperative Spontaneous Emission as a Many Body Eigenvalue Problem (2008)

Svidzinsky, Anatoly, Chang, Jun-Tao

We study emission of a single photon from a spherically symmetric cloud of N atoms (one atom is excited, N-1 are in ground state) and present an exact analytical expression for eigenvalues and...

Distilling two-atom distance information from intensity-intensity correlation functions (2006)

Chang, Jun-Tao, Evers, Jörg, Zubairy, M. Suhail

The intensity-intensity correlation function of the resonance fluorescence light of two two-level atoms driven by a resonant standing-wave laser field is examined. Our aim is to gain information on...

Measurement of the separation between atoms beyond diffraction limit (2005)

Chang, Jun-Tao, Evers, Joerg, Scully, Marlan O., Zubairy, M. Suhail

Precision measurement of small separations between two atoms or molecules has been of interest since the early days of science. Here, we discuss a scheme which yields spatial information on a system...
