The Signals of Doomsday I: False Higgs vacuum decay signatures
Amartya Sengupta, Dejan Stojkovic, De-Chang Dai
The measured standard model parameters indicate that we might live in a false Higgs vacuum, though with a very long lifetime. However, small black holes can serve as catalysers and…
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…
Quantum Gravity and Phenomenology: Dark Matter, Dark Energy, Vacuum Selection, Emergent Spacetime, and Wormholes
Per Berglund, De-Chang Dai, Douglas Edmonds +9
We discuss the relevance of quantum gravity to the frontier questions in high energy phenomenology: the problems of dark matter, dark energy, and vacuum selection as well as the pr…
