The volume of sales in lottery markets is huge. Since less than half the receipts are distributed as winnings, lottery tickets have an expected utility lower than their purchase price. Why do millions of people play the lottery week after week anyway, even though they are losing money? more
Since January 2007 the two space craft of NASA's STEREO mission orbit the Sun and provide us for the first time with simultaneously observed images of the Sun from two different viewpoints. The scientists at the MPS have developed analysis tools to generate three-dimensional models of plasma structures in the solar corona and compare them with models of the coronal magnetic field. These investigations aim at a better understanding of energetic eruptions and mass ejections of the solar corona. more
Unlike transistors based on single-crystalline silicon, organic thin-film transistors can be processed entirely at temperatures below 100°C. This allows the manufacturing of flexible or rollable flat panel displays. Of particular importance for the performance of the transistors are the properties of the gate dielectric. more
Bulk metal oxides exhibit a large variety of unusual electronic properties, such as high-temperature superconductivity and magnetic order. This article describes the synthesis of heterostructures of complex metal oxides as well as the characterization of interfaces contained in these structures by different experimental methods. The results may lead to a new generation of electronic devices. more
