Important Accomplishment From EMU Department of Physics Academician
Dr. Ali Ovgun, academician at the Eastern Mediterranean University (EMU) Faculty of Arts and Sciences, Department of Physics has published two articles with PhD student Kimet Jusufi from the Macedonian State University of Tetova.
The article titled “Tunneling of massive vector particles from rotating charged black Strings” was published in Springer’s journal titled “Astrophysics and Space Science” (SCI-2.263 Impact Factor). The second article titled “Massive Vector Particles Tunneling from Noncommutative Charged Black Holes and its GUP-corrected Thermodynamics” was also published in a Springer journal titled “The European Journal of Physics Plus” (SCI-1.377 Impact Factor)”.

Dr. Ovgun highlighted the importance of collaborative work, stating that such work is important as it promotes work carried out at the university and in the country. Dr. Ovgun noted that they are also collaborating with different groups from India, the USA and Turkey with an aim of understanding universe cosmology, Black holes and Wormholes.
Dr. Övgün, said that black holes possess gravitational fields so powerful that nothing can escape, not even light. The blackholes normally form when the remains of a dead star collapse under their own gravity, squeezing their mass together.
Scientists regarded black holes as simple objects — quite literally holes in space, described by just three variables: their mass, spin and charge. Using general relativity (Einstein’s theory of gravity), thermodynamics and quantum theory, Bekenstein and Hawking devised a formula showing that black holes have surprisingly high entropy — a measure of how many ways particles can be arranged inside the object. Quantum mechanically, black holes radiate, with a radiation known as Hawking radiation, named after the British physicist Stephen Hawking who first proposed it.
A micro black hole would be too small and short-lived to have much effect on its surroundings. Scientists’ only clue would be a burst of extra particles. But its effect on our understanding of nature at the quantum level would be enormous. If physicists produced microscopic black holes at the LHC, they would have proof that there are more than three dimensions of space.
Furthermore, string theory is the hottest thing in physics. Arising from the notion that matter and energy are fundamentally composed of tiny, vibrating strings rather than point like particles, this theory attempted to unify all known forces into a single, elegant package. Some physicists hailed string theory as the long-sought “theory of everything.”
In his research by using string theory and micro black holes, Dr. Ovgun investigated the tunneling of massive vector particles from static charged black strings. Then he calculated the corresponding tunneling rate and the Hawking temperature extending the calculations to the case of tunneling massive vector particles from a rotating charged black string. Finally, the corresponding tunneling rate and the Hawking temperature were recovered.
