Quantum coherent nanodynamics by the interplay of localized photons, electron-hole pairs, and phonons

Intriguing intrinsic properties of light quanta and related topics are reviewed by emphasizing the self-consistency of light-matter interactions and open nano-systems dynamics. It is pointed out that there still remain fundamental and challenging issues related to quantization of a finite nano-system interacting with a massive (i.e., localized) photon field,as well as with a hierarchical or structured phonon field. By using theoretical frameworks developed for an infinite system, some of quantum nature of a finite nano-system are revealed, and it is theoretically shown that dynamic phonon environments and the interplay of coherent and incoherent phonons play an important role in quantum coherent dynamics of electron-hole pairs interacting with massive photon fields.
