Many-body effects between unbosonized excitons
M. Combescot, O. Betbeder-Matibet
We here give a brief survey of our new many-body theory for composite excitons, as well as some of the results we have already obtained using it. In view of them, we conclude that,…
Dressed atom versus exciton polariton: From Rabi oscillations to the Fermi Golden rule
Francois Dubin, Monique Combescot, Bernard Roulet
We rederive the dressed atom and the exciton polariton within the {\it same} framework to make clear that their difference only comes from the number of electrons available for pho…
Major difference between true bosons and "proteons"
M. Combescot, O. Betbeder-Matibet
We call "proteons" -- from the ever-changing greek sea-god -- composite particles made of two fermions. Among them, are the semiconductor excitons, but also variou…
Theory of spin precession monitored by laser pulse
M. Combescot, O. Betbeder-Matibet
We first predict the splitting of a spin degenerate impurity level when this impurity is irradiated by a circularly polarized laser beam tuned in the transparency region of a semic…
Excitons dressed by a sea of excitons
M. Combescot, O. Betbeder-Matibet
We here consider an exciton embedded in a sea of identical excitons 0. If the excitons are bosonized, a bosonic enhancement factor, proportional to , is found for .…
The trion: two electrons plus one hole versus one electron plus one exciton
M. Combescot, O. Betbeder-Matibet, F. Dubin
We first show that, for problems dealing with trions, it is totally hopeless to use the standard many-body description in terms of electrons and holes and its associated Feynman di…
