Variational Ground State Approach for A Tunnelling Exciton Coupled to Phonons
Hamiltonian Ground state approximation Vacuum state
2010/4/9
In this paper a variational study of a tunnelling exciton (Frenkel exciton) coupled to an arbitrary number of phonon modes is presented. The results of our model are presented both for weak non-adiaba...
Exciton Polariton Emission from a Resonantly Excited GaAs Microcavity
Exciton Polariton a Resonantly Excited GaAs Microcavity
2010/10/26
Coherent emission efficiency in a 100°A GaAs SQW microcavity was enhanced one order when pumped resonantly at 10 K, compared to the off-resonant excitation. The usual kink observed in the exciton emis...
