Supersymmetric AdS Solitons, Ground States, and Phase Transitions in Maximal Gauged Supergravity
Particles, 2023 We review some recent soliton solutions in a class of four-dimensional supergravity theories. The latter can be obtained from black hole solutions by means of a double Wick rotation.

Five-dimensional Superfield Supergravity [PDF]
, 2001 We present a projective superspace formulation for matter-coupled simple supergravity in five dimensions. Our starting point is the superspace realization for the minimal supergravity multiplet proposed by Howe in 1981.

Two-loop supersymmetric QCD and half-maximal supergravity amplitudes [PDF]
, 2017 A bstractUsing the duality between color and kinematics, we construct two-loop four-point scattering amplitudes in N=2$$ \mathcal{N}=2 $$ super-Yang-Mills (SYM) theory coupled to Nf fundamental hypermultiplets.

Multi-Field versus Single-Field in the Supergravity Models of Inflation and Primordial Black Holes
Universe, 2021 We review the models unifying inflation and Primordial Black Hole (PBH) formation, which are based on the modified (Starobinsky-type) supergravity. We begin with the basic (Starobinsky) inflationary model of modified gravity and its alpha-attractor-type ...

Weyl invariance for generalized supergravity backgrounds from the doubled formalism [PDF]
, 2017 It has recently been shown that a set of the generalized type IIB supergravity equations follows from the requirement of the kappa-symmetry of the type IIB Green-Schwarz superstring theory defined on an arbitrary background.

On the Geometric Approach to the Boundary Problem in Supergravity
Universe, 2021 We review the geometric superspace approach to the boundary problem in supergravity, retracing the geometric construction of four-dimensional supergravity Lagrangians in the presence of a non-trivial boundary of spacetime.

The DNA of Calabi–Yau Hypersurfaces
Fortschritte der Physik, EarlyView.Abstract Genetic Algorithms are implemented for triangulations of four‐dimensional reflexive polytopes, which induce Calabi–Yau threefold hypersurfaces via Batyrev's construction. These algorithms are shown to efficiently optimize physical observables such as axion decay constants or axion–photon couplings in string theory compactifications.

Fundamental Supermultiplet in Twelve Dimensions
Frontiers in Physics, 2018 We discuss a set of local fields which provide the on-shell massless states expected for the fundamental linear representation of supersymmetry in twelve dimensions.

On the Starobinsky Model of Inflation from Supergravity
, 2013 We discuss how the higher-derivative Starobinsky model of inflation originates from N=1 supergravity. It is known that, in the old-minimal supergravity description written by employing a chiral compensator in the superconformal framework, the Starobinsky

The exceptional story of massive IIA supergravity [PDF]
, 2016 A bstractThe framework of exceptional field theory is extended by introducing consistent deformations of its generalised Lie derivative. For the first time, massive type IIA super-gravity is reproduced geometrically as a solution of the section ...
