摘要:	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 lambda/d, where lambda is the wavelength of the emitted photon and d is the lattice spacing. (C) 2004 Elsevier B.V. All rights reserved.
