Two components relativistic quantum wave equation for scalar bosons
Roland Combescot
We show that, in the relativistic regime, scalar bosons satisfy a quantum wave equation which is quite analogous to the Dirac equation. In contrast with the Klein-Gordon equation i…
Exciton ground-state energy with full hole warping structure
Roland Combescot, Shiue-Yuan Shiau
Most semiconductors, in particular III-V compounds, have a complex valence band structure near the band edge, due to degeneracy at the zone center. One peculiar feature is the warp…
Trion ground state energy: simple results
R. Combescot
We investigate the trion binding energy in a three-dimensional semiconductor, with bare Coulomb interaction between charges, and effective mass approximation for the electron and h…
The 3-body Coulomb problem
R. Combescot
We present a general approach for the solution of the three-body problem for a general interaction, and apply it to the case of the Coulomb interaction. This approach is exact, sim…
Scattering amplitudes for dark and bright excitons
Shiue-Yuan Shiau, Monique Combescot, Roland Combescot +2
Using the composite boson many-body formalism that takes single-exciton states rather than free carrier states as a basis, we derive the integral equation fulfilled by the exciton-…
Effects of fermion exchanges on the polarization of exciton condensates
M. Combescot, R. Combescot, M. Alloing +1
Exchange processes are responsible for the stability of elementary boson condensates with respect to their possible fragmentation. This remains true for composite bosons when singl…
