Collective Excitation Dynamics of a Cold Atom Cloud

T. S. do Espirito Santo, P. Weiss, A. Cipris +4

We study the time-dependent response of a cold atom cloud illuminated by a laser beam immediately after the light is switched on experimentally and theoretically. We show that coop…

Collective Multi-mode Vacuum Rabi Splitting

W. Guerin, T. S. do Espirito Santo, P. Weiss +4

We report the experimental observation of collective multi-mode vacuum Rabi splitting in free space. In contrast to optical cavities, the atoms couple to a continuum of modes, and…

Cooperative spontaneous emission via renormalization approach: Classical versus semi-classical effects

Carlos Eduardo Máximo, Romain Bachelard, Francisco Ednilson Alves dos Santos +1

We address the many-atom emission of a dilute cloud of two-level atoms through a renormalized perturbation theory. An analytical solution for the truncated coupled-dipole equations…

Roles of cooperative effects and disorder in photon localization: The case of a vector radiation field

L. Bellando, A. Gero, E. Akkermans +1

We numerically study photon escape rates from three-dimensional atomic gases and investigate the respective roles of cooperative effects and disorder in photon localization, while…

Robustness of Dicke subradiance against thermal decoherence

P. Weiss, A. Cipris, M. O. Araújo +2

Subradiance is the cooperative inhibition of the radiation by several emitters coupled to the same electromagnetic modes. It was predicted by Dicke in 1954 and only recently observ…

An optical lattice based method for precise measurements of atomic parity violation

A. Kastberg, T. Aoki, B. K. Sahoo +2

We propose a method for measuring parity violation in neutral atoms. It is an adaptation of a seminal work by Fortson [Phys. Rev. Lett. {\bf 70}, 2383 (1993)], proposing a scheme f…

Dressed dense atomic gases

Igor Lesanovsky, Beatriz Olmos, William Guerin +1

In dense atomic gases the interaction between transition dipoles and photons leads to the formation of many-body states with collective dissipation and long-ranged forces. Despite…

Comparison of three approaches to light scattering by dilute cold atomic ensembles

Igor M. Sokolov, William Guerin

Collective effects in atom-light interaction is of great importance for cold-atom-based quantum devices or fundamental studies on light transport in complex media. Here we discuss…
