A Separation between Divergence and Holevo Information for Ensembles
Rahul Jain, Ashwin Nayak, Yi Su
The notion of divergence information of an ensemble of probability distributions was introduced by Jain, Radhakrishnan, and Sen in the context of the ``substate theorem''. Since th…
A Note on Quantum Field Theories with a Minimal Length Scale
S. Hossenfelder
The aim of this note is to address the low energy limit of quantum field theories with a minimal length scale. The essential feature of these models is that the minimal length acts…
On the supergravity description of boost invariant conformal plasma at strong coupling
Paolo Benincasa, Alex Buchel, Michal P. Heller +1
We study string theory duals of the expanding boost invariant conformal gauge theory plasmas at strong coupling. The dual supergravity background is constructed as an asymptotic la…
Cascading DGP
Claudia de Rham, Gia Dvali, Stefan Hofmann +4
We present a higher codimension generalization of the DGP scenario which, unlike previous attempts, is free of ghost instabilities. The 4D propagator is made regular by embedding o…
The black hole dynamical horizon and generalized second law of thermodynamics
Song He, Hongbao Zhang
The generalized second law of thermodynamics for a system containing a black hole dynamical horizon is proposed in a covariant way. Its validity is also tested in case of adiabatic…
