A quantum-mechanical model for quantum well polaritons in semiconductor microcavities is presented. The real and imaginary parts of the polariton dispersion are obtained. They represent, respectively, the position and the linewidth of the luminescence peak ...
We calculate the one-electron Green's function of the two-dimensional (2D) attractive Hubbard model by coupling the electrons to pair fluctuations. The latter are approximated by homogeneous amplitude fluctuations and phase correlations corresponding to th ...
Detailed data on the momentum-resolved temperature dependence of the superconducting gap of Bi2Sr2CaCu2O8+x are presented, complemented by similar data on the intensity of the photoemission superconducting condensate spectral area. The gap anisotropy betwe ...
The authors have constructed two types of high-temperature superconducting (HTSC) bolometers, whose performance is essentially wavelength independent from λ~0.6 to 450 μm: The first is a microbridge, of dimensions 20×20 μm, and the second is a meander, cov ...
Longitudinal velocity measurements above a uniform dry lakebed were carried out to investigate the applicability of the random sweeping decorrelation hypothesis to thermally stratified turbulent flow. The higher order velocity structure functions of order ...
Granular aluminum wire networks forming square arrays of N×N=1E6 nodes connected by strips of 8-μm long were fabricated with photolithographic techniques. For strip resistances of the order of 1 kΩ the superconducting transition of the network, as evidence ...
We discuss the situation where attractive and repulsive portions of the interparticle potential both contribute significantly to glass formation. We introduce the square-well potential as prototypical model for this situation, and reject the Baxter model a ...
