Title: "Interacting classical and quantum systems"
Abstract:
A theory that couples quantum degrees of freedom to classical
degrees of freedom is of relevance to quantum measurement
theory and, more generally, of interest whenever it may be
appropriate to assume that some components of a physical
system can be modelled classically. However, despite many
attempts, fundamental difficulties have always arisen in trying
to implement such a ~Tmixed~T description. In my talk, I will
discuss a new approach to solving this problem based on a
canonical formalism that describes statistical ensembles on
configuration space. Applications include quantum systems
interacting with classical measuring apparatuses and equations
for coupling quantum fields to a classical space-time.
