Searching for small primordial black holes in planets, asteroids and here on Earth
De-Chang Dai, Dejan Stojkovic
Small primordial black holes could be captured by rocky planets or asteroids, consume their liquid cores from inside and leave hollow structures. We calculate the surface density a…
Shedding new light on the absence of fermionic superradiance and maximal infalling rate of fermions into a black hole
De-Chang Dai, Dejan Stojkovic
Using the complete classification of the bases in the rotating black hole background we separate superradiance from the Hawking effect. We first find that there is spontaneous part…
Separating the superradiant emission from the Hawking radiation from a rotating black hole
De-Chang Dai, Dejan Stojkovic
Emission of particles created in the background of a rotating black hole can be greatly amplified taking away rotational energy of a black hole. This amplification affects both par…
Superluminal propagation along the brane in space with extra dimensions
De-Chang Dai, Dejan Stojkovic
We demonstrate that a model with extra dimensions formulated in Csaki et al. (Phys Rev D 62, 045015), which fatefully reproduces Friedmann-Robertson-Walker (FRW) equations on the b…
Bulk entropy is crucial to validate the second law of the extended black hole thermodynamics
De-Chang Dai, Djordje Minic, Dejan Stojkovic
The extended black hole thermodynamics in which the cosmological constant plays the role of pressure significantly enriches the phase structure of the theory. In order to understan…
Interaction of cosmological domain walls with large classical objects, like planets and satellites, and the flyby anomaly
De-Chang Dai, Djordje Minic, Dejan Stojkovic
Cosmological domain walls can be formed as a result of symmetry breaking at any epoch during the evolution of our universe. We study their interaction with a classical macroscopic…
