Quantum fluctuations on curved spacetimes cause the emission of pairs of particles from the quantum vacuum, as in the Hawking effect from black holes. We use an optical analogue to gravity to investigate the influence of the curvature on quantum e

The dielectric behaviour of technical air was investigated in a slightly divergent electric field (coaxial arrangement) varying the gas pressure and the voltage polarity as well. The investigated pressure range was from 300 to 750 kPa. The HV electro

Annual Report Conference on Electrical Insulation and Dielectric Phenomena.
The statistical behaviour of atmospheric air was investigated in a divergent electric field (rod-plane arrangement). The experimental campaign refers to both polarities as well as different gap distances (10, 30, 50 and 70 mm). The average breakdown

The discharge phenomena were investigated in a background uniform field (plate - needle to plate arrangement) varying the needle protrusion (length=3 to 5 mm; tip radius= 200 /spl mu/m), the gas pressure (300 and 500 kPa) as well as the gas mixture c

We have efficiently generated colinearly-propagrating entangled photon pairs from nondegenerate type-I and degenerate type-II quasi-phase matched parametric downconverters based on periodically-poled lithium niobate and potassium titanyl phosphate, r

We introduce two new materials for the production of optical thin films. PatinalR Substance H4 evaporant is a new mixture for high index layers of 2.1 at 500 nm. PatinalR Substance Ml evaporant is a new mixture for medium index layers of about 1.7 at
