Critical N=(1,1) General Massive Supergravity
Nihat Sadik Deger, George Moutsopoulos, Jan Rosseel
In this paper we study the supermultiplet structure of General Massive Supergravity at non-critical and critical points of its parameter space. To do this, we f…
Quarter-BPS solutions in three-dimensional N=16 supergravity and the Liouville equation
George Moutsopoulos
We show how by assuming at least 8 real timelike supersymmetries in the maximally supersymmetric three-dimensional ungauged supergravity and a further simplifying Ansatz, we are na…
Warped anti-de Sitter in 3d (2,0) Supergravity
George Moutsopoulos
We comment on the ubiquity of the so-called warped anti-de Sitter spacetimes in three-dimensional (2,0) supergravity theory. By using isometry-invariant tensors and simple counting…
Supersymmetric solutions of Topologically Massive Supergravity
Nihat Sadik Deger, George Moutsopoulos
We first make a Killing spinor analysis for a general three-dimensional off-shell supergravity and find conditions for a bosonic background to preserve some supersymmetry…
All timelike supersymmetric solutions of three-dimensional half-maximal supergravity
Nihat Sadik Deger, George Moutsopoulos, Henning Samtleben +1
We first classify all supersymmetric solutions of the 3-dimensional half-maximal ungauged supergravity that possess a timelike Killing vector coming from the Killing spinor bilinea…
Effective actions of non-geometric fivebranes
Athanasios Chatzistavrakidis, Fridrik Freyr Gautason, George Moutsopoulos +1
An interesting consequence of string dualities is that they reveal situations where the geometry of a string background appears to be globally ill-defined, a phenomenon usually ref…
