Superradiance of J-aggregates: correspondence between infinite disordered chain and regular chain of finite length
The radiation decay of excitons in a slightly disordered molecule chain is considered. The degree of disordering dictates the excitonic state length that determines the enhancement of the decay rate Г (superradiance). Г was calculated versus disordering degree and temperature and compared with the c...
