Mechanisms of fatigue crack propagation Ni 3 Al alloy under supergravity are studied by the molecular dynamics method. The initial model is a [100](010) in Al. Changes microstructure evolution, growth rate, and stress intensity factor compared analyzed without with supergravity. results show that deformation mechanisms tip slip bands along a/6[112] direction dislocation analysis absence cyclic ...

This paper presents a detailed discussion of the issue of supergravity perturbations around the flat five dimensional superspace required for manifest superspace formulations of the supergravity side of the AdS5/CFT4 Correspondence

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.

A bstract We construct supersymmetric AdS 3 solutions of D = 11 supergravity, dual to d 2, $$ \mathcal{N} N (0 , 2) SCFTs, that are associated with M5-branes wrapping two different four-dimensional orbifolds. In one case the orbifold is a spindle fibred over another spindle, while in other it Riemann surface ...

A bstract I study generalisations of U-duality transformations which do not rely on the existence isometries. start by providing more details a recently proposed generalised map between solutions type IIA supergravity form M 7 × S 3 , with NSNS flux, and 11-dimensional supergravity, in three-sphere is replaced four-dimensional geometry encodes three-algebra structure constants. then show that w...

We present a consistent theory of N = 1 supergravity in twelve-dimensions with the signature (10, 2). Even though the formulation uses two null vectors violating the manifest Lorentz covariance, all the super-space Bianchi identities are satisfied. After a simple dimensional reduction to ten-dimensions, this theory reproduces the N = 1 supergravity in ten-dimensions, supporting the consistency ...

Using Minkowski space AdS/CFT prescription we explicitly compute in the low-energy limit two-point correlation function of the boundary stress-energy tensor in a large class of type IIB supergravity backgrounds with regular translationally invariant horizon. The relevant set of supergravity backgrounds includes all geometries which can be interpreted via gauge theory/string theory correspondenc...

We obtain a new gauged D = 6, N = (1, 1) pure supergravity by a generalised consistent Kaluza-Klein reduction of M-theory on K3×R. The reduction requires a conspiratory gauging of both the Cremmer-Julia type global (rigid) symmetry and the homogeneous rescaling symmetry of the supergravity equations of motion. The gauged supergravity is different from the Romans D = 6 gauged supergravity in tha...

We consider the conditions necessary for obtaining perturbative maximal supergravity in d dimensions as a decoupling limit of type II superstring theory compactified on a (10-d) torus. For dimensions d=2 and d=3, it is possible to define a limit in which the only finite-mass states are the 256 massless states of maximal supergravity. However, in dimensions d>or=4, there are infinite towers of a...
