Dicke model simulation via cavity-assisted Raman transitions

Understand

The Dicke model is of fundamental importance in quantum mechanics for understanding the collective behaviour of atoms coupled to a single electromagnetic mode.

• In this paper, we demonstrate a Dicke-model simulation using cavity-assisted Raman transitions in a configuration using counter-propagating laser beams.
• The observations indicate that motional effects should be included to fully account for the results and these results are contrasted with the experiments using single-beam and co-propagating configurations.
• A theoretical description is given that accounts for the beam geometries used in the experiments and indicates the potential role of motional effects.
