Infinitesimally thin static scalar shells surrounding charged Gauss-Bonnet black holes
Shahar Hod
We reveal the existence of a new form of spontaneously scalarized black-hole configurations. In particular, it is proved that Reissner-Nordström black holes in the highly charged r…
Upper bound on the energies of the emitted Hawking quanta
Shahar Hod
Using Thorne's hoop conjecture, it is argued that the energies of the Hawking quanta emitted from canonical Schwarzschild black holes are bounded from above by the simple quantum r…
The holographic entropy bound in higher-dimensional spacetimes: As strong as ever
Shahar Hod
The celebrated holographic entropy bound asserts that, within the framework of a self-consistent quantum theory of gravity, the maximal entropy (information) content of a physical…
Viscosity bound versus the universal relaxation bound
Shahar Hod
For gauge theories with an Einstein gravity dual, the AdS/CFT correspondence predicts a universal value for the ratio of the shear viscosity to the entropy density, . The…
Charged reflecting stars supporting charged massive scalar field configurations
Shahar Hod
The recently published no-hair theorems of Hod, Bhattacharjee, and Sarkar have revealed the intriguing fact that horizonless compact reflecting stars {\it cannot} support spatially…
Ultra-spinning exotic compact objects supporting static massless scalar field configurations
Shahar Hod
Horizonless spacetimes describing highly compact exotic objects with reflecting (instead of absorbing) surfaces have recently attracted much attention from physicists and mathemati…
