Mechanisms of charge transfer and redistribution in LaAlO3/SrTiO3 revealed by high-energy optical conductivity
In condensed matter physics the quasi two-dimensional electron gas at the interface of two different insulators, polar LaAlO3 on nonpolar SrTiO3 (LaAlO3/SrTiO3) is a spectacular and surprising observation. This p...

Bilayer manganites reveal polarons in the midst of a metallic breakdown
The origin of colossal magnetoresistance (CMR) in manganese oxides is among the most challenging problems in condensed-matter physics today. The true nature of the low-temperature electronic phase of these mat...

Kristallurie, Mikroerythrurie und Proteinure: Häufigkeit des Vorkommens und der Koinzidenz
Die Kristallurie an und für sich ist eine normale Erscheinung sowohl bei Steinkranken als auch bei gesunden Personen. Daß sie trotzdem in der Steinforschung von großem und in neuerer Zeit stark zunehmendem Int...
