Journal ArticleDOI
Cooperative spontaneous emission of N atoms: Many-body eigenstates, the effect of virtual Lamb shift processes, and analogy with radiation of N classical oscillators
TL;DR: In this paper, the collective emission of a single photon from a cloud of two-level atoms (one excited, one ground state) is considered and the problem is reduced to finding eigenfunctions and eigenvalues of an integral equation.
Journal ArticleDOI
Dynamical evolution of correlated spontaneous emission of a single photon from a uniformly excited cloud of N atoms.

TL;DR: The correlated spontaneous emission from a dense spherical cloud of N atoms uniformly excited by absorption of a single photon is studied to find that the decay of such a state depends on the relation between an effective Rabi frequency Omega proportional square root N and the time of photon flight through the cloud R/c.
Journal ArticleDOI
Cooperative spontaneous emission as a many-body eigenvalue problem
TL;DR: In this paper, the authors studied the emission of a single photon from a spherically symmetric cloud of atoms and presented an exact analytical expression for eigenvalues and eigenstates of this many-body problem.
Journal ArticleDOI
Measurement of the separation between atoms beyond diffraction limit
TL;DR: In this article, the spatial information on a system of two identical atoms placed in a standing wave laser field is extracted from the collective resonance fluorescence spectrum, relying entirely on far-field imaging techniques.
Journal ArticleDOI
Distilling two-atom distance information from intensity-intensity correlation functions
TL;DR: In this paper, 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 to gain information on the distance between the two atoms from observables accessible in experiments.
