Schrödinger invariant solutions of type IIB with enhanced supersymmetry

چکیده
We construct the Killing spinors for a class of supersymmetric solutions of type IIB supergravity that are invariant under the non-relativistic Schrödinger algebra. The solutions depend on a five-dimensional SasakiEinstein space and it has been shown that they admit two Killing spinors. Here we will show that, for generic Sasaki-Einstein space, there are special subclasses of solutions which admit six Killing spinors and we determine the corresponding superisometry algebra. We also show that for the special case that the Sasaki-Einstein space is the round five-sphere, the number of Killing spinors can be increased to twelve.

Solutions of type IIB and D=11 supergravity with Schrödinger(z) symmetry
We construct families of supersymmetric solutions of type IIB andD = 11 supergravity that are invariant under the non-relativistic Schrödinger(z) algebra for various values of the dynamical exponent z. The new solutions are based on fiveand seven-dimensional Sasaki-Einstein manifolds, respectively, and include supersymmetric solutions with z = 2.

We show that the higher-dimensional vanishing scalar invariant (VSI) spacetimes with fluxes and dilaton are solutions of type IIB supergravity, and we argue that they are exact solutions in string theory. We also discuss the supersymmetry properties of VSI spacetimes. [PACS: 04.20.Jb, 04.65.+e]
متن کاملBPS Analysis of the Charged Soliton Solutions of D-brane Worldvolume Theory from the Viewpoint of Target-space Supersymmetry
We investigate BPS properties of the charged soliton solutions of D-brane worldvolume theory, which is described by the supersymmetric Dirac-Born-Infeld action, by means of the N = 2 target-space supersymmetry algebra. Our results agree with those obtained previously. We also extend our BPS analysis to the case where axion background exists. ∗[email protected] D-branes play an ...
متن کاملSupersymmetry Constraints on Type IIB Supergravity
Supersymmetry is used to derive conditions on higher derivative terms in the effective action of type IIB supergravity. Using these conditions, we are able to prove earlier conjectures that certain modular invariant interactions of order (α) relative to the Einstein–Hilbert term are proportional to eigenfunctions of the Laplace operator on the fundamental domain of SL(2,ZZ). We also discuss how...
متن کاملNo-scale supersymmetry breaking vacua and soft terms with torsion
We analyze the conditions to have no-scale supersymmetry breaking solutions of type IIA and IIB supergravity compactified on manifolds of SU(3)-structure. The supersymmetry is spontaneously broken by the intrinsic torsion of the internal space. For type IIB orientifolds with O9 and O5-planes the mass of the gravitino is governed by the torsion class W1, and the breaking is mediated through F-te...
