A Quantum Pigeonhole Principle and Two Semidefinite Relaxations of Communication Complexity Open
We study semidefinite relaxations of $Π_1$ combinatorial statements. By relaxing the pigeonhole principle, we obtain a new "quantum" pigeonhole principle which is a stronger statement. By relaxing statements of the form "the communication …

Resonant Laser Induced Breakdown Spectroscopy for quantitative elemental depth profile analysis of WTa coating Open
This work reports on the procedure of Resonant-LIBS, in which ablation and subsequent excitation is achieved by fine-tuning an Optical Parametric Oscillator (OPO) laser to the resonant transition of tungsten (W I) at 255.14 nm and analyzin…

Electric field in APTD in nitrogen determined by EFISH, FNS/SPS ratio, <i>α</i>-fitting and electrical equivalent circuit model Open
We investigate the electric field development in weak microseconds-lasting atmospheric pressure Townsend discharge operated in a barrier discharge arrangement in pure nitrogen. The electric field is determined using four different methods:…

Solution to the perturbation of LIF measurements via photodissociation, OH measurement in atmospheric‐pressure multihollow DBD Open
This study solves the problem of the invasivity of laser‐induced fluorescence (LIF) measurements caused by photodissociation. It is shown with the example of OH LIF that the excess signal caused by laser‐induced photodissociation can be di…

Laser-Induced Fluorescence of Hydroxyl (OH) Radical in Cold Atmospheric Discharges Open
The application of laser-induced fluorescence (LIF) to measurement of absolute concentration of hydroxyl radicals in cold atmospheric discharges is described. Though only the case of OH is presented, the method can be directly applied to o…
