While the theory of linear response fimctions in many body theory has developed into a substantial lore over the past decades, rather little is known about the properties and behavior of higher order (quadratic, etc.) response functions of many body

Analytical properties of the quadratic density response and quadratic dynamical structure functions: Conservation sum rules and frequency moments

Autor: J. M. Rommel, Gabor J. Kalman

Publikováno v: Physical Review E. 54:3518-3530

The quadratic density response function and the quadratic dynamical structure function ~the Fourier transform of the equilibrium three-point density correlations! contain important information about a many body system; they are also ingredients for a

Photoluminescence measurement of the facet temperature of 1 W gain‐guided AlGaAs/GaAs laser diodes

Autor: J. M. Rommel, P. Gavrilovic, F. P. Dabkowski

Publikováno v: Journal of Applied Physics. 80:6547-6549

The output facet temperature of high‐power AlGaAs/GaAs single quantum well (SQW) laser diodes was measured during operation. The front output facets were passivated with Al2O3 coatings. The spectral shift of photoluminescence from the cladding laye
