To improve on it, we will propose an abstract characterization of a Dirac operator on noncommutative curved spacetimes, in terms of a minimal set of axioms. Namely, it should be ...

Macroscopic Local Realism: How Do We Define It and Is It
... validity of local realism at a more macroscopic level might one day be answered. The first step is to give a sensible quantitative meaning to the distinction between a microscopic and macroscopic experiment and to microscopic and macroscopic measurements. In essence, we classify an experiment as mac ...

Local Equilibrium States in Quantum Field Theory in Curved

In the description of macroscopic physical systems, one often nds the term local temperature, meaning that there is a spacetime dependent parameter that somehow takes the rôle of temperature in systems which are not everywhere and at any time (i.e. globally) in equilibrium. However, it is only fo ...
