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…
The Operator Manifold Formalism. II. Physical Applications
G. T. Ter-Kazarian
Within the operator manifold approach (part I, hep-th/9812181) we derive the Gell-Mann-Nishijima relation and flavour group, whereas the leptons are particles with integer electric…
The Operator Manifold Formalism. I
G. T. Ter-Kazarian
The suggested operator manifold formalism enables to develop an approach to the unification of the geometry and the field theory. We also elaborate the formalism of operator multim…
