Abstract

Description

We represent a new microscopic approach that allows studying the propagation properties of microwaves in a Bose-Einstein condensate of alkali atoms. It is assumed that the frequency of signal is tuned up to the transition between hyperfine ground state levels of such atoms. Pulse slowing conditions dependence on the system parameters is found. It is shown that the slowed signal can propagate in mentioned system with rather small energy loss. Such phenomenon is also studied in case of hyperfine levels Zeeman splitting. A possibility of ultra-slow microwaves observing in a condensed gas of cesium atoms is discussed.
