Dirac particles' tunnelling from 5-dimensional rotating black strings influenced by the generalized uncertainty principle
The standard Hawking formula predicts the complete evaporation of black
holes. Taking into account effects of quantum gravity, we investigate fermions'
tunnelling from a 5-dimensional rotating black string. The temperature is
determined not only by the string, but also affected by the quantum number of
the emitted fermion and the effect of the extra spatial dimension. The quantum
correction slows down the increase of the temperature, which naturally leads to
the remnant in the evaporation.Comment: 11page
Remarks on remnants by fermions' tunnelling from black strings
Hawking's calculation is unable to predict the final stage of the black hole
evaporation. When effects of quantum gravity are taken into account, there is a
minimal observable length. In this paper, we investigate fermions' tunnelling
from the charged and rotating black strings. With the influence of the
generalized uncertainty principle, the Hawking temperatures are not only
determined by the rings, but also affected by the quantum numbers of the
emitted fermions. Quantum gravity corrections slow down the increases of the
temperatures, which naturally leads to remnants left in the evaporation.Comment: 16pages, Publised in Advances in High Energy Physics, Volume 2014,

Thermodynamics and weak cosmic censorship conjecture in extended phase spaces of anti-de Sitter black holes with particles' absorption
The thermodynamics and weak cosmic censorship conjecture in extended phase
spaces of charged anti-de Sitter black holes describing the massive gravity are
investigated by the absorptions of the scalar particle and fermion. The
cosmological constant is seen as a pressure with a conjugate volume. The first
law of thermodynamics is recovered. The second law of thermodynamics is
violated in the extended phase space of the extremal black hole. For the
near-extremal and extremal black holes, the validity of weak cosmic censorship
conjecture is tested by evaluating the minimum values of the metric function
. It is found that they remain their near-extremity and extremity when the
particles are absorbed
