  • Black hole with a scalar field as a particle accelerator 
    Zaslavskii O. (2017)
    © 2017 World Scientific Publishing CompanyWe consider stationary axially symmetric black holes with the background scalar field and test particles that can interact with this field directly. Then, particle collision near ...
  • High energy particle collisions and geometry of horizon 
    Zaslavskii O. (2016)
    © 2016 World Scientific Publishing Company.We consider collision of two geodesic particles near the lightlike surface (black hole horizon or naked singularity) of such an axially symmetric rotating or static metric that ...
  • Negative energy states in the Reissner Nordström metric 
    Zaslavskii O.B. (2021)
    We consider electrogeodesics on which the energy E 0 in the Reissner-Nordström metric. It is shown that outside the horizon there is exactly one turning point inside the ergoregion for such particles. This entails that ...
  • Rapidly rotating spacetimes and collisional super-Penrose process 
    Zaslavskii O. (2016)
    © 2016, Springer Science+Business Media New York.We consider generic axially symmetric rotating spacetimes and examine particle collisions in the ergoregion. The results are generic and agree with those obtained in the ...
  • Rotation as an origin of high energy particle collisions 
    Zaslavskii O. (2016)
    © 2016 World Scientific Publishing Company.We consider collision of two particles in rotating spacetimes without horizons. If the metric coefficient responsible for rotation of spacetime is big enough, the energy of ...

  • Super-Penrose process due to collisions inside ergosphere 
    Zaslavskii O. (2017)
    © 2017 World Scientific Publishing Company.If two particles collide inside the ergosphere, the energy in the center of mass frame can be made unbound provided at least one of particles has a large negative angular momentum ...

  • Super-Penrose process for extremal charged white holes 
    Zaslavskii O.B. (2020)
    © 2020 World Scientific Publishing Company. We consider collision of two particles 1 and 2 near the horizon of the extremal Reissner-Nordström (RN) black hole that produces two other particles 3 and 4. There exists such a ...
  • Super-Penrose process for extremal rotating neutral white holes 
    Zaslavskii O.B. (2020)
    © 2020, Springer Science+Business Media, LLC, part of Springer Nature. We consider collision of two particles 1 and 2 near the horizon of the extremal rotating axially symmetric neutral generic black hole producing particles ...
