Janis–Newman Algorithm: Generating Rotating and NUT Charged Black Holes
Universe, 2017 In this review we present the most general form of the Janis–Newman algorithm. This extension allows generating configurations which contain all bosonic fields with spin less than or equal to two (real and complex scalar fields, gauge fields, metric ...

Six-dimensional origin of gravity mediated brane to brane supersymmetry breaking
, 2014 Four dimensional supergravities may be the right framework to describe particle physics at low energies. Its connection to the underlying string theory can be implemented through higher dimensional supergravities which bear special characteristics. Their

On Calabi‐Yau Manifolds at Strong Topological String Coupling
Fortschritte der Physik, Volume 72, Issue 12, December 2024.Abstract It was recently shown that integrating out M2 states on Calabi‐Yau manifolds captures non‐perturbative topological string physics in the free energy. In this note, It has been shown that the resulting expression manifests a certain duality symmetry: the free energy at strong string coupling is equal to the Calabi‐Yau period at weak string ...

Ultraviolet Cancellations in Half-Maximal Supergravity as a Consequence of the Double-Copy Structure
, 2012 We show that the double-copy structure of gravity forbids divergences in pure half-maximal (16 supercharge) supergravity at four and five points at one loop in ...

Pure de Sitter supergravity [PDF]
, 2015 Using superconformal methods we derive an explicit de Sitter supergravity action invariant under spontaneously broken local N = 1 supersymmetry. The supergravity multiplet interacts with a nilpotent Goldstino multiplet.

de Sitter State in Heterotic String Theory
Fortschritte der Physik, Volume 72, Issue 11, November 2024.Abstract Recent no‐go theorems have ruled out four‐dimensional classical de Sitter vacua in heterotic string theory. On the other hand, the absence of a well‐defined Wilsonian effective action and other related phenomena also appear to rule out such time‐dependent vacua with de Sitter isometries, even in the presence of quantum corrections.

New Janus interfaces from four-dimensional $$N=3$$ N = 3 gauged supergravity
European Physical Journal C: Particles and FieldsWe construct new supersymmetric Janus solutions from four-dimensional $$N=3$$ N = 3 gauged supergravity coupled to eight vector multiplets with $$SO(3)\times SU(3)$$ S O ( 3 ) × S U ( 3 ) gauge group.

Solution of the deformed Schwarzschild metric by the Yang-Baxter equation
Қарағанды университетінің хабаршысы. Физика сериясы, 2019 In this article, an open-closed string map formulated by Seiberg & Whitten was used to solve problems of generalized supergravity, including the deformed Schwarzschild metric.
