Analytical approach to semiconductor Bloch equations
M. Combescot, O. Betbeder-Matibet, M. N. Leuenberger
Although semiconductor Bloch equations have been widely used for decades to address ultrafast optical phenomena in semiconductors, they have a few important drawbacks: (i) Coulomb…

Density expansion of the energy of N close-to-boson excitons
O. Betbeder-Matibet, M. Combescot
Pauli exclusion between the carriers of excitons induces novel many-body effects, quite different from the ones generated by Coulomb interaction. Using our commutation techniqu…

The Effective Bosonic Hamiltonian for Excitons Reconsidered
M. Combescot, O. Betbeder-Matibet
The effective bosonic hamiltonian for excitons, extensively quoted up to now, cannot be correct because it is (surprisingly) non-hermitian. The oversight physically originates from…
