Statistics and Collective Properties of Frenkel Excitons
Statistics and Collective Properties of Frenkel Excitons
This chapter describes the approximate second quantization and approximate transition to boson picture. Using exact transformation from paulions to bosons, the collective properties of an ideal three-dimensional gas of paulions are considered. The statistics and the collective properties of Frenkel excitons are discussed, taking into account the dynamic exciton-exciton interaction. The fermionic character of Frenkel excitons in one-dimensional molecular crystals is demonstrated.
Keywords: approximate second quantization, paulions, bosons, collective properties, exciton-exciton interaction, one-dimensional molecular crystals
