Energy extraction from Kerr black holes by rigidly rotating strings
Shunichiro Kinoshita, Takahisa Igata, Kentaro Tanabe
In this paper, we show that a rigidly rotating string can extract the rotational energy from a rotating black hole. We consider Nambu-Goto strings stationary with respect to a coro…
Self-similar motion of a Nambu-Goto string
Takahisa Igata, Tsuyoshi Houri, Tomohiro Harada
We study the self-similar motion of a string in a self-similar spacetime by introducing the concept of a self-similar string, which is defined as the world sheet to which a homothe…
Escape probability of the super-Penrose process
Kota Ogasawara, Tomohiro Harada, Umpei Miyamoto +1
We consider a head-on collision of two massive particles that move in the equatorial plane of an extremal Kerr black hole, which results in the production of two massless particles…
