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…
Identities in Nonlinear Realizations of Supersymmetry
Haishan Liu, Hui Luo, Mingxing Luo +1
In this paper, we emphasize that a UV SUSY-breaking theory can be realized either linearly or nonlinearly. Both realizations form the dual descriptions of the UV SUSY-breaking theo…
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…
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…
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…
Critical Points of D-Dimensional Extended Gravities
S. Deser, Haishan Liu, H. Lu +3
We study the parameter space of D-dimensional cosmological Einstein gravity together with quadratic curvature terms. In D>4 there are in general two distinct (anti)-de Sitter vacua…
