Comments on ``Improved limit on quantum-spacetime modifications of Lorentz symmetry from observations of gamma-ray blazars"
T. Jacobson, S. Liberati, D. Mattingly
We address several criticisms by Amelino-Camelia of our recent analyses of two observational constraints on Lorentz violation at order E/M_{Planck}. In particular, we emphasize the…
Bi-refringence versus bi-metricity
Matt Visser, Carlos Barcelo, Stefano Liberati
In this article we carefully distinguish the notion of bi-refringence (a polarization-dependent doubling in photon propagation speeds) from that of bi-metricity (where the two phot…
Analogue models of and for gravity
Matt Visser, Carlos Barcelo, Stefano Liberati
Condensed matter systems, such as acoustics in flowing fluids, light in moving dielectrics, or quasiparticles in a moving superfluid, can be used to mimic aspects of general relati…
Vacuum Effects in Gravitational Fields: Theory and Detectability
S. Liberati
In this thesis, we investigate quantum vacuum effects in the presence of gravitational fields. After discussing the general theory of vacuum effects in strong fields we apply it to…
Problems in Black Hole Entropy interpretation
S. Liberati
In this work some proposals for black hole entropy interpretation are exposed and investigated. In particular I will firstly consider the so called ``entanglement entropy" interpre…
