Hybrid States of Biomolecules in Strong-Coupling Regime

详细

The strong coupling of exciton and plasmon states is the result of the reversible energy exchange between the excited states of atomic exciton systems or molecules and the electromagnetic field. This leads to the formation of hybrid (mixed) states whose energies differ from those of the exciton and photon. To date, the implementation of strong-coupling hybrid states has been attracting great attention in terms of designing state-of-the-art emitting systems and quantum information technologies; controlling chemical reaction efficiency and targeted influence on biological systems; and applying the observed effects in medicine, microelectronics, robotics technologies, and other fields. This review deals with a model of strong light-matter interaction and its characteristics, ways to the practical implementation of hybrid states (including those in biological systems), and parameters affecting strong coupling. The recent advances in practical applications of strong coupling effects, prospects for their use, and the problems entailed are discussed as well.
