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,…
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…
