LO Phonon-Induced Exciton Dephasing in Quantum Dots: An Exactly Solvable Model
arXiv:cond-mat/0605545 · doi:10.1103/PhysRevLett.98.187401
Abstract
It is widely believed that, due to its discrete nature, excitonic states in a quantum dot coupled to dispersionless LO phonons form everlasting mixed states (exciton polarons) showing no line broadening in the spectrum. This is indeed true if the model is restricted to a limited number of excitonic states in a quantum dot. We show, however, that extending the model to a large number of states results in LO phonon-induced spectral broadening and complete decoherence of the optical response.
