Experimental study on the possibility of formation of a condensate of excited states in a substance (Rydberg matter)

Abstract

The results of experimental study of a condensate of cesium excited states (Rydberg matter) are presented. The possibility of condensate formation was predicted theoretically first by Prof. E.A. Manykin and coauthors from the Russian Research Center Kurchatov Institute and experimentally observed by L. Holmlid and coauthors from the Chalmers University, Sweden. In a thermionic energy converter with interelectrode medium, where, according to the data of Swedish researchers, Rydberg matter is formed, we observed similarities and distinctions between our and Swedish data on the formation of a condensate of cesium excited states.
