AdS and Lifshitz Black Holes in Conformal and Einstein-Weyl Gravities
H. Lu, Y. Pang, C. N. Pope +1
We study black hole solutions in extended gravities with higher-order curvature terms, including conformal and Einstein-Weyl gravities. In addition to the usual AdS vacuum, the the…
f(R) Theories of Supergravities and Pseudo-supergravities
Haishan Liu, H. Lu, Zhao-Long Wang
We present f(R) theories of ten-dimensional supergravities, including the fermionic sector up to the quadratic order in fermion fields. They are obtained by performing the conforma…
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…
On Hybrid (Topologically) Massive Supergravity in Three Dimensions
Hong Lu, Yi Pang
A class of hybrid (topologically) massive off-shell supergravities coupled to an on-shell matter scalar multiplet was recently constructed. The auxiliary field in the off-shell mul…
Thermodynamical Metrics and Black Hole Phase Transitions
Haishan Liu, H. Lu, Mingxing Luo +1
An important phase transition in black hole thermodynamics is associated with the divergence of the specific heat with fixed charge and angular momenta, yet one can demonstrate tha…
Massive Three-Dimensional Supergravity From R+R^2 Action in Six Dimensions
H. Lu, C. N. Pope, E. Sezgin
We obtain a three-parameter family of massive N=1 supergravities in three dimensions from the 3-sphere reduction of an off-shell N=(1,0) six-dimensional Poincare supergravity that…
Instability by Chern-Simons and/or Transgressions
H. Lu, Zhao-Long Wang
It was demonstrated recently that there is an upper bound of the Chern-Simons coupling of the five-dimensional Einstein-Maxwell theory, beyond which the electrically charged AdS_2…

H. Lu, Zhao-Long Wang
We establish the general formalism for constructing metrics of Calabi-Yau (p+1)-folds in terms of that of a p-fold by adding a complex-line bundle. We present a few explicit low-ly…
On M-Theory Embedding of Topologically Massive Gravity
H. Lu, Zhao-Long Wang
We show that topologically massive gravity can be obtained by the consistent Kaluza-Klein reduction from recently constructed seven-dimensional gravity with topological terms. The…
Seven-Dimensional Gravity with Topological Terms
H. Lu, Yi Pang
We construct new seven-dimensional gravity by adding two topological terms to the Einstein-Hilbert action. For certain choice of the coupling constants, these terms may be related…

H. Lu, Yi Pang, Zhao-Long Wang
Recently, a metric construction for the Calabi-Yau 3-folds from a four-dimensional hyperkahler space by adding a complex line bundle was proposed. We extend the construction by add…
