Renormalized frequency shift of a Wannier exciton in a one-dimensional system

Chen, Yueh-Nan · Chuu, Der-San

Original · EN

The radiative frequency shift of superradiant exciton in a one-dimensional system is calculated. It is shown that a finite frequency shift can be obtained after proper renormalization. The value of the shift is inversely proportional to the factor λd, where λ is the wavelength of the emitted photon and d is the lattice spacing.
