The Non-Relativistic Superparticle in a Curved Background [PDF]
, 2014 Using a component formulation, we construct the supersymmetric action for a superparticle in a three-dimensional Newton-Cartan supergravity background and clarify its symmetries. Our construction proceeds by first constructing the superparticle in a flat

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

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.

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 ...

Physical Review Letters, 2022 Minimal massive gravity in three dimensions propagates a single massive spin-2 mode around an AdS vacuum. It is distinguished by allowing for vacua with positive central charges of the asymptotic conformal algebra and a bulk graviton of positive energy.

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.

Oxide Interface of Gallium‐Based Liquid Metals: Beneficial Bridge or Hidden Risk?
ChemistryEurope, EarlyView.Discussion on oxide interfaces in gallium‐based liquid metals have concentrated on their properties, behaviors, and related applications. However, the molecular mechanisms underlying effects, as well as the differences between the presence and absence of the oxide layer, have been less thoroughly discussed.

Supergravity at the boundary of AdS supergravity
, 2009 We give a general analysis of AdS boundary conditions for spin-3/2 Rarita-Schwinger fields and investigate boundary conditions preserving supersymmetry for a graviton multiplet in AdS_4.

Recent advances in boosting interfacial bubble dynamics with external fields
Droplet, EarlyView.External physical fields, including acoustic, magnetic, thermal, mechanical, and optical stimuli, accelerate the entire bubble‐dynamics sequence of nucleation, growth, and detachment. Abstract The efficiency of industrial electrocatalytic reactions depends not only on generating gaseous products but also on their detachment from the catalyst surface ...

On the determination of the dilaton-antisymmetric tensor couplings in supergravity theories [PDF]
, 1993 A new approach is provided to determine the dilaton--antisymmetric tensor coupling in a supergravity theory by considering the static supersymmetric field configuration around a super extended object, which is consistently formulated in a curved ...
