Nonlinear refractive index of warm rubidium vapor
L. Kardum, G. Premec, N. Å antiÄ +1
The potential to precisely control both the linear and nonlinear index of refraction through optical manipulation of the atomic states has recently pushed warm alkali vapors to the…

Collective light shifts of many longitudinal cavity modes induced by coupling to a cold-atom ensemble
Marin ÃujiÄ, Mateo Kruljac, Lovre Kardum +4
We experimentally study the interaction between a cold atom cloud and many longitudinal modes of a high quality Fabry-Perot cavity, by measuring signatures of collective light shif…
