OPERA neutrinos and relativity
Giovanni Amelino-Camelia, Laurent Freidel, Jerzy Kowalski-Glikman +1
In a recent study, Cohen and Glashow argue that superluminal neutrinos of the type recently reported by OPERA should be affected by anomalous Cherenkov-like processes. This causes…
The black hole information paradox and relative locality
Lee Smolin
We argue that the recently proposed principle of relative locality offers a new way to resolve the black hole information puzzle.
Relative locality: A deepening of the relativity principle
Giovanni Amelino-Camelia, Laurent Freidel, Jerzy Kowalski-Glikman +1
We describe a recently introduced principle of relative locality which we propose governs a regime of quantum gravitational phenomena accessible to experimental investigation. This…
A real ensemble interpretation of quantum mechanics
Lee Smolin
A new ensemble interpretation of quantum mechanics is proposed according to which the ensemble associated to a quantum state really exists: it is the ensemble of all the systems in…
Relative locality and the soccer ball problem
Giovanni Amelino-Camelia, Laurent Freidel, Jerzy Kowalski-Glikman +1
We consider the behavior of macroscopic bodies within the framework of relative locality, which is a recent proposal for Planck scale modifications of the relativistic dynamics of…
Gamma ray burst delay times probe the geometry of momentum space
Laurent Freidel, Lee Smolin
We study the application of the recently proposed framework of relative locality to the problem of energy dependent delays of arrival times of photons that are produced simultaneou…
An action for higher spin gauge theory in four dimensions
Nima Doroud, Lee Smolin
An action principle is presented for Vasiliev's Bosonic higher spin gauge theory in four spacetime dimensions. The action is of the form of a broken topological field theory, and a…
The principle of relative locality
Giovanni Amelino-Camelia, Laurent Freidel, Jerzy Kowalski-Glikman +1
We propose a deepening of the relativity principle according to which the invariant arena for non-quantum physics is a phase space rather than spacetime. Descriptions of particles…
