Abstract

The coherent states of the electromagnetic field modify the fundamental properties of Bloch electrons such as effective mass, band gap, charge, and coupling coefficient to phonons. The effects of this renormalization depend on the phases as well as on the intensities of coherent modes. Among the renormalization effects are shifts of spectral edges for absorption and emission to higher frequencies, decrease in radiative interband transitions, and increase in free carrier absorptions and emissions. The coherent field renormalization shows that the electron-hole system is thermodynamically unstable with respect to the growth of coherent modes when its population is inverted.
