Kerr black holes as circular polarizers
De-Chang Dai
We study the retrograde second caustics of extremal Kerr black holes, where the intensity of the light beam is infinitely magnified. We find that the caustics of different polarize…
Entropy created when colliding particles fall into a black hole
De-Chang Dai
If two particles collide in the vicinity of a black hole horizon, their center of mass energy is practically unlimited, so another black hole with a large mass and thus entropy can…
The spin correlation of fermion pairs created by a Kerr black hole gravitational potential
De-Chang Dai
We study the properties of massive fermions created and scattered by a rotating Kerr black hole. The helicities of the scattered fermions can vary during propagation. A fermion wit…
Studies on particle creation during the universe expansion with a laser system
De-Chang Dai, Changbo Fu
While two highly intensive laser beams collide, they create a region where the refractive index varies so quickly that photons are created. The variance of the refractive index is…
