Consistent S3 reductions of six-dimensional supergravity
Samtleben, Henning; Sarıoğlu, Bahtiyar Özgür (American Physical Society (APS), 2019-10-7)
We work out the consistent AdS(3) x S-3 truncations of the bosonic sectors of both the six-dimensional = N = (1,1) and N = (2,0) supergravity theories. They result in inequivalent three-dimensional half-maximal SO(4) gauge...
Circularly symmetric solutions of minimal massive gravity at its merger point
Sarıoğlu, Bahtiyar Özgür (IOP Publishing, 2019-07-25)
I find all the static circularly symmetric solutions of minimal massive 3D gravity at its merger point, construct stationary versions of these and discuss some of their geometric and physical properties. It turns out that ...
Stationary Lifshitz black hole of New Massive Gravity
Sarıoğlu, Bahtiyar Özgür (IOP Publishing, 2019-01-10)
I present the stationary Lifshitz black hole solution of three-dimensional New Massive Gravity theory and study its elementary geometric and thermodynamical properties.
Supersymmetric solutions of N=(1,1) general massive supergravity
Deger, N. S.; Nazari, Z.; Sarıoğlu, Bahtiyar Özgür (American Physical Society (APS), 2018-5-29)
We construct supersymmetric solutions of three-dimensional N = (1, 1) general massive supergravity (GMG). Solutions with a null Killing vector are, in general, pp-waves. We identify those that appear at critical points of ...
Kundt solutions of minimal massive 3D gravity
Deger, Nihat Sadik; Sarıoğlu, Bahtiyar Özgür (AMER PHYSICAL SOC, ONE PHYSICS ELLIPSE, COLLEGE PK, MD 20740-3844 USA, 2015-11-04)
We construct Kundt solutions of minimal massive gravity theory and show that, similar to topologically massive gravity (TMG), most of them are constant scalar invariant (CSI) spacetimes that correspond to deformations of r...
All timelike supersymmetric solutions of three-dimensional half-maximal supergravity
DEĞER, NİHAT SADIK; Moutsopoulos, George; Samtleben, Henning; Sarıoğlu, Bahtiyar Özgür (2015-06-22)
We first classify all supersymmetric solutions of the 3-dimensional half-maximal ungauged supergravity that possess a timelike Killing vector by considering their identification under the complexification of the local symm...
A supersymmetric reduction on the three-sphere
DEĞER, NİHAT SADIK; Samtleben, Henning; Sarıoğlu, Bahtiyar Özgür; Van den Bleeken, Dieter (2015-01-01)
We present the embedding of three-dimensional SO(4) proportional to R-6 gauged N = 4 supergravity with quaternionic target space SO(4, 4)/(SO(4) x SO(4)) into D = 6, N = (1, 0) supergravity coupled to a single chiral tenso...
Stationary Lifshitz black holes ofR2-corrected gravity theory
Sarıoğlu, Bahtiyar Özgür (American Physical Society (APS), 2011-12-7)
In this short note, I present a generalization of a set of static D-dimensional (D >= 3) Lifshitz black holes, which are solutions of the gravitational model obtained by amending the cosmological Einstein theory with the a...
Thermodynamics of Lifshitz black holes
Devecioglu, Deniz Olgu; Sarıoğlu, Bahtiyar Özgür (American Physical Society (APS), 2011-06-23)
We apply the recently extended conserved Killing charge definition of Abbott-Deser-Tekin formalism to compute, for the first time, the energies of analytic Lifshitz black holes in higher dimensions. We then calculate the t...
Conserved Killing charges of quadratic curvature gravity theories in arbitrary backgrounds
Devecioglu, Deniz Olgu; Sarıoğlu, Bahtiyar Özgür (2011-01-24)
We extend the Abbott-Deser-Tekin procedure of defining conserved quantities of asymptotically constant-curvature spacetimes, and give an analogous expression for the conserved charges of geometries that are solutions of qu...
