f(R) Gravities, Killing Spinor Equations, "BPS" Domain Walls and Cosmology
Haishan Liu, H. Lu, Zhao-Long Wang
We derive the condition on f(R) gravities that admit Killing spinor equations and construct explicit such examples. The Killing spinor equations can be used to reduce the fourth-or…
Solutions of Free Higher Spins in AdS
H. Lu, Kai-Nan Shao
We consider free massive and massless higher integer spins in AdS backgrounds in general D dimensions. We obtain the solutions corresponding to the highest-weight state of the spin…
Linearized Modes in Extended and Critical Gravities
Yi-Xin Chen, H. Lu, Kai-Nan Shao
We construct explicit solutions for the linearized massive and massless spin-2, vector and scalar modes around the AdS spacetimes in diverse dimensions. These modes may arise in ex…
Critical and Non-Critical Einstein-Weyl Supergravity
H. Lu, C. N. Pope, E. Sezgin +1
We construct N=1 supersymmetrisations of some recently-proposed theories of critical gravity, conformal gravity, and extensions of critical gravity in four dimensions. The total ac…
Gauged Kaluza-Klein AdS Pseudo-supergravity
Haishan Liu, H. Lu, Zhao-Long Wang
We obtain the pseudo-supergravity extension of the D-dimensional Kaluza-Klein theory, which is the circle reduction of pure gravity in D+1 dimensions. The fermionic partners are ps…
Pseudo-Supergravity Extension of the Bosonic String
H. Lu, C. N. Pope, Zhao-Long Wang
We construct a ``pseudo-supersymmetric" fermionic extension of the effective action of the bosonic string in arbitrary spacetime dimension D. The theory is invariant under pseudo-s…
Killing Spinors for the Bosonic String
H. Lu, Zhao-Long Wang
We obtain the effective action for the bosonic string with arbitrary Yang-Mills fields, up to the α' order, in general dimensions. The form of the action is determined by the requi…
Conformal Gravity and Extensions of Critical Gravity
H. Lu, Yi Pang, C. N. Pope
Higher-order curvature corrections involving the conformally-invariant Weyl-squared action have played a role in two recent investigations of four-dimensional gravity; in critical…
Killing Spinors for the Bosonic String and the Kaluza-Klein Theory with Scalar Potentials
Haishan Liu, H. Lu, Zhao-Long Wang
The paper consists mainly of two parts. In the first part, we obtain well-defined Killing spinor equations for the low-energy effective action of the bosonic string with the confor…
Pseudo-supersymmetry, Consistent Sphere Reduction and Killing Spinors for the Bosonic String
H. Lu, C. N. Pope, Zhao-Long Wang
Certain supergravity theories admit a remarkable consistent dimensional reduction in which the internal space is a sphere. Examples include type IIB supergravity reduced on S^5, an…
On Black Hole Stability in Critical Gravities
Haishan Liu, H. Lu, Mingxing Luo
We consider extended cosmological gravities with Ricci tensor and scalar squared terms in diverse dimensions. These theories admit solutions of Einstein metrics, including the Schw…
Pseudo-Killing Spinors, Pseudo-supersymmetric p-branes, Bubbling and Less-bubbling AdS Spaces
H. Lu, Zhao-Long Wang
We consider Einstein gravity coupled to an n-form field strength in D dimensions. Such a theory cannot be supersymmetrized in general, we nevertheless propose a pseudo-Killing spin…
Critical Gravity in Four Dimensions
H. Lu, C. N. Pope
We study four-dimensional gravity theories that are rendered renormalisable by the inclusion of curvature-squared terms to the usual Einstein action with cosmological constant. By…
