We show how VCSELs with elongated shapes of the emission area can achieve higher output powers and wall-plug efficiency compared to standard circular or quadratic VCSELs. We identified an improved homogeneity of the carrier concentration in the quant

In this paper we present the results of physical investigations on mercury-free automotive discharge lamps—also known as the so-called Xenon lamps. In this type of lamp we replace Hg by ZnI2 for environmental reasons while keeping the standard meta

A numerical model of the radiative transfer in high pressure metal halide discharge lamps is used to determine line broadening parameters for atomic scandium lines. The determined broadening constants are in qualitative agreement with theoretical est

We present an analytic five-loop calculation for the additive renormalization constant A(u,epsilon) and the associated renormalization-group function B(u) of the specific heat of the O(n) symmetric phi^4 theory within the minimal subtraction scheme.

We present an analytic four-loop calculation of the free energy in three dimensions within the $O(n)$ symmetric ${\ensuremath{\varphi}}^{4}$ theory at infinite cutoff for general n above and below ${T}_{c}.$ It is shown that Goldstone singularities a

We present the results of a three-loop calculation of amplitude functions within the O(n) symmetric φ4 theory in three dimensions for general n below Tc. An appropriate treatment of Goldstone modes avoids spurious singularities for n>1. Several univ
