A T-matrix many-particle theory for coherently coupled superlattice optics
The high- order Coulomb correlations described by T-matrix diagrams in both carrier occupation and polarization functions are studied here with a Keldysh- Green’s Functions formalism. Numerical applications for low dimensional semiconductor systems illustrate the relevance of the effects and their i...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | The high- order Coulomb correlations described by T-matrix diagrams in both carrier occupation and polarization functions are studied here with a Keldysh- Green’s Functions formalism. Numerical applications for low dimensional semiconductor systems illustrate the relevance of the effects and their importance for realistic nonlinear optical spectra calculations. A frequency and momentum resolved numerical demonstration of the Mott transition at the T-matrix level is presented.
