Journal of High Energy Physics, 2009 We study the linearized approximation of N=1 topologically massive supergravity around AdS3. Linearized gravitino fields are explicitly constructed. For appropriate boundary conditions, the conserved charges demonstrate chiral behavior, so that chiral gravity can be consistently extended to chiral supergravity.

Journal of High Energy Physics, 2017 Supergravity with eight supercharges in a four-dimensional Euclidean space is constructed at the full non-linear level by performing an off-shell time-like reduction of five-dimensional supergravity. The resulting four-dimensional theory is realized off-shell with the Weyl, vector and tensor supermultiplets and a corresponding multiplet calculus ...

International Journal of Modern Physics A, 1992 We quantize the classical gauge theory of N=2 w∞ supergravity and show how the underlying N=2 super-w∞ algebra gets deformed into an N=2 super-W∞ algebra. Both algebras contain the N=2 super-Virasoro algebra as a subalgebra. We discuss how one can extract from these results information about quantum N=2 WN supergravity theories containing a finite ...

On the Vacuum Structure of the
Universe, 2021 We consider N=4 conformal supergravity with an arbitrary holomorphic function of the complex scalar S which parametrizes the SU(1,1)/U(1) coset. Assuming non-vanishings vevs for S and the scalars in a symmetric matrix Eij of the 10¯ of SU(4) R-symmetry ...

Supergravity metallurgy: principles, experimental methods, techniques, and applications
工程科学学报, 2021 Supergravity significantly increases the gravity difference between two phases and thus can accelerate phase separation in solid–liquid mixtures, liquid–liquid mixtures, and liquid–bubble mixtures that have high temperatures and viscosities.

N=2 Chiral Supergravity in (10 + 2)-Dimensions As Consistent Background for Super (2 + 2)-Brane [PDF]
, 1997 We present a theory of N=2 chiral supergravity in (10+2)-dimensions. This formulation is similar to N=1 supergravity presented recently using null-vectors in 12D.

Removal of Low-Content Impurities from Pure Al by Supergravity Combined with Semi-Solid Method
Metals, 2023 Recently, the purification technology for high-purity aluminum (Al) has become the focus and difficulty of the majority of researchers. In this study, a novel approach for removing iron (Fe) impurities from pure Al via combining the supergravity field ...

, 2006 We adapt the spinorial geometry method to investigate supergravity backgrounds with near maximal number of supersymmetries. We then apply the formalism to show that the IIB supergravity backgrounds with 31 supersymmetries preserve an additional ...

Holographic RG flows in $$N=4$$ N=4 SCFTs from half-maximal gauged supergravity
European Physical Journal C: Particles and Fields, 2018 We study four-dimensional $$N=4$$ N=4 gauged supergravity coupled to six vector multiplets with semisimple gauge groups $$SO(4)\times SO(4)$$ SO(4)×SO(4) , $$SO(3,1)\times SO(3,1)$$ SO(3,1)×SO(3,1) and $$SO(4)\times SO(3,1)$$ SO(4)×SO(3,1) . All of these
