is unique to quantum physics and describes systems that are hotter than any positive-
temperature system. For decades, negative temperatures have been shown in a number of …

Abstract The Stefan-Boltzmann law can estimate particle emission power and lifetime of a
black hole. However, in modified gravity theories, new parameters in the action can cause …

A bstract It is well known that an asymptotically flat four-dimensional Kerr black hole has a
smaller (specific) entropy than a Schwarzschild black hole of the same mass. We show here …

A bstract It has been argued that the rate at which the interior of an AdS black hole evolves is
dual to the rate of evolution of the (quantum state of the) strongly coupled matter on the …

A “large” AdS black hole can attain equilibrium with its own Hawking radiation, and in that
condition it is thought to be dual to a strongly coupled field theory, also at equilibrium. But …

The fact that AdS black hole interior geometries are time-dependent presents two
challenges: first, to holographic duality (the boundary matter tends to equilibrate, often very …

In the standard holographic “dictionary”, the deep infrared of the strongly coupled boundary
field theory is studied by examining the bulk region near to the event horizon of a simple …

In this work, we study the evaporation behaviors of asymptotically flat charged black holes in
the Einstein-Horndeski gravity theory. Based on the thermodynamics of the Horndeski black …

The initial idea underlying the Weak Gravity Conjecture is that extremal black holes must
always be “unstable”, in the sense that they should slowly decay by emitting either particles …

It has been argued that the rate at which the interior of an AdS black hole evolves is dual to
the rate of unitary evolution of the strongly coupled matter on the boundary which, according …
