Acceleration of particles near the inner black hole horizon
O. B. Zaslavskii
We study the possibility of obtaining unbound energy E_{c.m.} in the centre of mass frame when two particles collide near the inner black hole horizon. We consider two different ca…
Membrane paradigm and entropy of black holes in the Euclidean action approach
José P. S. Lemos, Oleg B. Zaslavskii
The membrane paradigm approach to black holes fixes in the vicinity of the event horizon a fictitious surface, the stretched horizon, so that the spacetime outside remains unchange…
Acceleration of particles by rotating black holes: near-horizon geometry and kinematics
O. B. Zaslavskii
Nowadays, the effect of infinite energy in the centre of mass frame due to near-horizon collisions attracts much attention.We show generality of the effect combining two seemingly…
Neutral and charged matter in equilibrium with black holes
K. A. Bronnikov, O. B. Zaslavskii
We study the conditions of a possible static equilibrium between spherically symmetric, electrically charged or neutral black holes and ambient matter. The following kinds of matte…
Collisions of massive and massless particles around rotating black holes: general analysis
O. B. Zaslavskii
We consider collisions between massive (electrons) and massless (photons) particles near the horizon of a rotating black hole. Similarly to collisions between massive particles, th…
Acceleration of particles by black holes: kinematic explanation
O. B. Zaslavskii
A new simple and general explanation of the effect of acceleration of particles by black holes to infinite energies in the centre of mass frame is suggested. It is based on kinemat…
