Hawking radiation as the cosmic censor
Koray Düztaş, İbrahim Semiz
Hawking radiation acts as a cosmic censor since it carries away the angular momentum of the black hole, proportionally more than its mass. In this work we first show that an extrem…
The decoupling problem of the Proca equation; and treatment of Dirac, Maxwell and Proca fields on the resulting pp-wave spacetimes
Koray Düztaş, İbrahim Semiz
In this work we take a formal approach to the problem of decoupling Proca equations in curved space-times. We use Newman-Penrose (NP) two-spinor formalism to represent the Proca ve…
What do the cosmological supernova data really tell us?
İbrahim Semiz, A. Kazım Çamlıbel
Not much by themselves, aparently. We try to reconstruct the scale factor of the universe from the SNe Ia data, i.e. the luminosity distance , using only the cosmo…
Approximations for the natural logarithm from solenoid-toroid correspondence
Ibrahim Semiz
It seems reasonable that a toroid can be thought of approximately as a solenoid bent into a circle. The correspondence of the inductances of these two objects gives an approximatio…
