Prof. Felix Finster (Regensburg)

An introduction to causal fermion systems and the causal action principle

Abstract:
The theory of causal fermion systems is an approach to describe fundamental physics. It gives quantum mechanics, general relativity and quantum field theory as limiting cases and is therefore a candidate for a unified physical theory. Moreover, causal fermion systems provide a general framework for modelling and analyzing non-smooth spacetime structures. The dynamics of a causal fermion system is described by a nonlinear variational principle, the causal action principle.

The aim of the talk is to give a simple introduction. I will proceed chronologically and explain step by step how the underlying concepts and objects evolved from 1990 to today. This will lead us to the abstract definitions. The underlying physical principles will be discussed. At the end of the talk, I will briefly outline how to get the connection to a quantum state in the algebraic formulation.
