Article: Uniqueness of charged static asymptotically flat black holes in dynamical ChernSimons gravity
[Show abstract] [Hide abstract]
ABSTRACT: Making use of the conformal positive energy theorem we prove the uniqueness of fourdimensional static electrically charged black holes being the solution of ChernSimons dynamical gravity equations of motion. We assume that black hole spacetime contains an asymptotically flat spacelike hypersurface with compact interior and nondegenerate components of the event horizon.Physical Review D 07/2013; 88(2). · 4.69 Impact Factor 
Article: AbelianHiggs hair on stationary axisymmetric black hole in EinsteinMaxwellaxiondilaton gravity
[Show abstract] [Hide abstract]
ABSTRACT: We studied, both analytically and numerically, an Abelian Higgs vortex in the spacetime of stationary axisymmetric black hole being the solution of the lowenergy limit of the heterotic string theory, acted as hair on the black hole background. Taking into account the gravitational backreaction of the vortex we show that its influence is far more subtle than causing only a conical defect. As a consequence of its existence, we found that the ergosphere was shifted as well as event horizon angular velocity was affected by its presence. Numerical simulations reveal the strong dependence of the vortex behaviour on the black hole charge and mass of the Higgs boson. For large masses of the Higgs boson and large value of the charge, black hole is always pierced by an Abelian Higgs vortex, while small values of the charge and Higgs boson mass lead to the expulsion of Higgs field.Physical Review D 10/2013; 88(8). · 4.69 Impact Factor  [Show abstract] [Hide abstract]
ABSTRACT: We proved that strictly stationary EinsteinMaxwellaxiondilaton spacetime with negative cosmological constant could not support a nontrivial configuration of complex scalar fields. We considered the general case of the arbitrary number of U(1) gauge fields in the theory under consideration.Physical review D: Particles and fields 05/2013; 87(8).
