AI Article Synopsis
- The interaction between emitted photons and Coulomb forces can lead to a dynamic coherent state in exciton-polariton systems without needing phonon thermalization or other typical relaxation processes.
- Exact diagonalization methods are used to analyze a finite system, specifically a quantum dot interacting with the lowest-energy photon mode in a microcavity.
- These findings suggest that such interactions may create coherent states in quantum systems under certain conditions.
Article Abstract
We show that the combined effect of photon emission and Coulomb interactions may drive an exciton-polariton system towards a dynamical coherent state, even without phonon thermalization or any other relaxation mechanism. Exact diagonalization results for a finite system (a multilevel quantum dot interacting with the lowest-energy photon mode of a microcavity) are presented in support of this statement.
