Separability of Klein-Gordon Equation on Near Horizon Extremal Myers-Perry Black Hole
Hovhannes Demirchian, Saeedeh Sadeghian
We investigate the separability of Klein-Gordon equation on near horizon of d-dimensional rotating Myers-Perry black hole in two limits : 1) generic extremal case and 2) extremal v…
Integrable systems connected with black holes
Hovhannes Demirchian
This work is devoted to the study of some important questions in general relativity. They include topics related to astrophysical shock waves, impulsive signals, gravitational memo…
Geodesic congruences, impulsive gravitational waves and gravitational memory
Martin O'Loughlin, Hovhannes Demirchian
In this paper we introduce a new approach to the study of the effects that an impulsive wave, containing a mixture of material sources and gravitational waves, has on a geodesic co…
On integrability of geodesics in near-horizon extremal geometries: Case of Myers-Perry black holes in arbitrary dimensions
Hovhannes Demirchian, Armen Nersessian, Saeedeh Sadeghian +1
We investigate dynamics of probe particles moving in the near-horizon limit of extremal Myers-Perry black holes in arbitrary dimensions. Employing ellipsoidal coordinates we show t…
Klein-Gordonization: mapping superintegrable quantum mechanics to resonant spacetimes
Oleg Evnin, Hovhannes Demirchian, Armen Nersessian
We describe a procedure naturally associating relativistic Klein-Gordon equations in static curved spacetimes to non-relativistic quantum motion on curved spaces in the presence of…
Note on constants of motion in conformal mechanics associated with near horizon extremal Myers-Perry black holes
Hovhannes Demirchian
We investigate dynamics of probe particles moving in the near-horizon limit of (2N+1)-dimensional extremal Myers-Perry black hole (in the cases of N=3,4,5) with arbitrary rotation…
