Experimental investigations of using silica aerogel to harvest unconcetrated sunlight in a solar thermal receiver
… heat in this range requires expensive optics or vacuum systems in order to utilize the diluted solar energy flux reaching the earth’s surface. Current flat plate solar collectors have significant heat losses and achieving higher temperatures without using concentrating optics remains a challenge. …

Oppenheimer-Snyder Collapse in the BSSN Formalism
… simulation code for modeling of spherical vacuum systems using the BSSN formalism. Diagnostics provide comparison of our results with theoretical predictions for the simplified case of a stationary black hole. Further work is required to introduce matter terms and move from spherical to …

A System for Measuring Radiation Induced Chemical Products in Atmospheric Gases Using Optical Detection Methods
… is followed by a description of the optical and vacuum systems that were available and the modifications required to integrate the optical system into the vacuum chamber to achieve the ability to optically monitor the ozone levels in a controlled atmosphere. Both the ringdown data collection and …

Effiziente Erzeugung verschränkter Photonenpaare
… requirements of these experiments were high (vacuum systems, stronge dye-lasers, etc.) whereas the efficiency of the source was quite low. An important step forward was the introduction of spontaneous parametric down conversion (SPDC), which has become the most common source in quantum optics …
