General Talk

The interaction of quantum fields with classical backgrounds gives rise to several interesting effects. For the study of the non-perturbative ones, the application of suitable resummation techniques is essential.

In this talk we will review recent advances in the development of appropriate resummation techniques, with special emphasis on those related to the first quantised approach. In...

General Talk

Supergeometric Quantum Field Theories (SG-QFTs) are theories that go beyond the standard supersymmetric framework, since they allow for general scalar-fermion field transformations on the configuration space of a supermanifold, without requiring an equality between bosonic and fermionic degrees of freedom. After revisiting previous considerations, we extend them by calculating the one-loop...
