This blog is run by me, Jochen Zahn. I am postdoc in the theoretical particle physics group at the Institute of Theoretical Physics at Leipzig University, Germany.

My research interests are mainly on Quantum Field Theory on curved space-times or in the presence of external potentials. In these fields, emphasis on the locality of all constructions turned out to be very fruitful, thus motivating the title of my blog. More (contact) information can be found on my homepage.

In this blog, I mainly intend to provide background information about my research.
