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…
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…
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…
