Approaching a dynamical extreme black hole horizon

Achilleas P. Porfyriadis, Christopher Rosen, Georgios Tsaraktsidis

We give an explicit closed form description of the late-time near-horizon approach to dynamical extreme Reissner-Nordstrom (DERN) black holes. These are spherically symmetric dynam…

Spindle solutions, hyperscalars and smooth uplifts

Igal Arav, Jerome P. Gauntlett, Matthew M. Roberts +1

We construct solutions of type IIB supergravity, where is a smooth bundle over a spindle , which are dual to SCFTs in…

Spindle solutions with hyperscalars in gauged supergravity

Igal Arav, Jerome P. Gauntlett, Jaeha Park +2

We construct new classes of supersymmetric solutions, where is a spindle. Such solutions can arise as the near horizon limit of supersymmetric, ac…

de Sitter versus Anti de Sitter flows and the (super)gravity landscape: Part II

Elias Kiritsis, Sergio Morales-Tejera, Christopher Rosen

Generic solutions are studied in Einstein-scalar gravity in an ansatz that can interpolate between de Sitter and Anti-de Sitter regimes. The scalar potential is arbitrary. All solu…

Superconformal Monodromy Defects in ABJM and mABJM Theory

Igal Arav, Jerome P. Gauntlett, Yusheng Jiao +2

We study supergravity solutions which are dual to one-dimensional superconformal defects in SCFTs. We consider defects in ABJM theory with monodromy for $U(1)^4\subset…

Superconformal Monodromy Defects in =4 SYM and LS theory

Igal Arav, Jerome P. Gauntlett, Yusheng Jiao +2

We study type IIB supergravity solutions that are dual to two-dimensional superconformal defects in SCFTs which preserve supersymmetry. We consider soluti…
