Background independence in a nutshell
Carlo Rovelli, Daniele Colosi, Luisa Doplicher +3
We study how physical information can be extracted from a background independent quantum system. We use an extremely simple `minimalist' system that models a finite region of 3d eu…

Generalized Tomonaga-Schwinger equation from the Hadamard formula
Luisa Doplicher
A generalized Tomonaga--Schwinger equation, holding on the entire boundary of a {\em finite} spacetime region, has recently been considered as a tool for studying particle scatteri…

Minkowski vacuum in background independent quantum gravity
Florian Conrady, Luisa Doplicher, Robert Oeckl +2
We consider a local formalism in quantum field theory, in which no reference is made to infinitely extended spacial surfaces, infinite past or infinite future. This can be obtained…
