Outline of Final Research Achievements

Quantum degenerate gases generated by laser cooling are useful quantum systems for simulating origins of physical functionalities in real materials and finding novel quantum many-body phenomena. In this project, we first succeeded in generating a Bose-Einstein condensate of rubidium atoms. Pulsed laser excitation of these atoms to Rydberg states lead to a quantum degenerate gas in which atoms strongly interact with each other through their electric dipoles. We also succeeded in observing dynamics of the gas under the interaction.
