Exciton physics: basic to advanced
·
Module 11
Bose-Einstein Condensation of Excitons
1
Excitons as Composite Bosons
Establish the conditions under which excitons can be treated as composite bosons.
2
Critical Temperature of BEC in a 3D Exciton Gas
Derive the critical temperature for Bose-Einstein condensation (BEC) of a 3D ideal exciton gas.
3
BKT Transition in 2D Exciton Systems
Describe the Berezinskii-Kosterlitz-Thouless (BKT) transition for interacting 2D exciton systems.
4
Bogoliubov Approximation for Exciton Gas Quasiparticle Spectrum
Apply the Bogoliubov approximation to derive the quasiparticle spectrum of a weakly interacting exciton gas.
5
Exciton BEC Signatures
Evaluate experimental signatures of exciton BEC, such as macroscopic coherence, narrowed emission lines, and the formation of a spectral condensate.
