Dekohärenz und Tunneln
Tunneling in quantum mechanics can be described by a quantum mechanical probability current penetrating through a barrier. An observer perceives this as a decay rate, i.e. as a likelihood of a particle to appear in a certain time interval. Decoherence theory is to be applied here in order to describe this without invoking the collapse of a wave function. The resolution of this question may help to resolve apparent paradoxes in phase transitions through bubble nucleation.

Effektive Wirkung für Tunnelprozesse in der Quantenmechanik
Methods from quantum field theory are to be applied to quantum mechanics in order to find loop corrections to tunneling rates. Once the calculations are working, we aim to find situations where these corrections are large and potentially identify condensed matter systems where the pertaining effects are relevant.
