The Second-Quantized Theory of Frenkel Excitons

The Second-Quantized Theory of Frenkel Excitons

Excitations in Organic Solids

Vladimir M. Agranovich

Oxford University Press

This chapter presents a second quantized theory of Frenkel excitons. An energy operator for a molecular crystal in the second quantization is introduced, and excitonic states for crystals with one and more molecules per unit cell are considered. The paulions are introduced in consideration of the two-level molecular model, and exact transformation from paulions to bosons is demonstrated. The mechanism of self-trapping of Frenkel excitons and spectra and transport of self-trapped excitons are discussed. The interaction of excitons and elementary lattice excitations is considered. The results of calculations of exciton states for some molecular crystals (anthracene, naphthalene, tetracene and pentacene) are presented.

Keywords:   molecular crystals, crystal energy operator, paulions, bosons, self-trapped Frenkel excitons, excitons transport, exciton states, anthracene, naphthalene, tetracene
