    We review aspects of black hole thermodynamics, and show how entanglement of a quantum field between the inside and outside of a horizon can account for the areaproportionality of black hole entropy, provided the field ...

    We re-examine the idea that the origin of black-hole entropy may lie in the entanglement of quantum fields between inside and outside of the horizon. Motivated by the observation that certain modes of gravitational ...

    Understanding the area-proportionality of black hole entropy (the ‘Area Law’) from an underlying fundamental theory has been one of the goals of all models of quantum gravity. A key question that one asks is: where are ...

    Considering the entanglement between quantum field degrees of freedom inside and outside the horizon as a plausible source of black hole entropy, we address the question: where are the degrees of freedom that give rise ...
