deSitter vacua from uplifting D-terms in effective supergravities from realistic strings
A. Achucarro, B. de Carlos, J. A. Casas +1
We study the possibility of using the D-term associated to an anomalous U(1) for the uplifting of AdS vacua (to dS or Minkowski vacua) in effective supergravities arising from stri…
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…
Some aspects of the phenomenology of canonical noncommutative spacetimes
Luisa Doplicher
I describe some phenomenological contexts in which it is possible to investigate effects induced by (string-motivated) canonical noncommutative spacetime. Due to the peculiar struc…
D-particles and the localization limit in quantum gravity
Giovanni Amelino-Camelia, Luisa Doplicher
Some recent studies of the properties of D-particles suggest that in string theory a rather conventional description of spacetime might be available up to scales that are significa…
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…
