Excitonic molecule and its bose condensation

Excitonic Molecules
Part of the Lecture Notes in Physics book series (LNP, volume 57)


The three optical responses of excitonic molecule; giant two-photon absorption, luminescence and optical conversion from single exciton are theoretically discussed. Then the luminescence spectrum characteristic of Bose-condensed excitonic molecules is presented by taking account of the final state interaction between the excitonic molecule and the single exciton at the finite system temperature. Lastly is answered a question whether the third order optical process of the giant two-photon absorption due to the excitonic molecule and its subsequent emission leaving the single exciton behind is considered as two separable processes of absorption and emission or as an inseparable process like two-photon Raman scattering.
