dc.description.abstract
Essentially, every realistic quantum system is open, which means that it is interacting with another
system that we call an environment. An effective description of open systems leads
to predictions of effects like decoherence or frequency shifts. In this talk, I will
present a recently developed first principle-based formalism for describing open
systems in quantum field theory. Subsequently, I will discuss how it predicts open
quantum dynamical effects that can be used to probe physics beyond the standard
models of particles and cosmology in modern quantum experiments. In particular, I
will show that frequency shifts induced by hypothetical scalar fields in atom
interferometry experiments have the potential to put new constraints on some
popular scalar field models.
