A note on field equations in generalized theories of gravity
Jun-Jin Peng
In the work (arXiv:1109.3846 [gr-qc]), to obtain a simple and economic formulation of field equations for generalised theories of gravity described by the Lagrangian $\sqrt{-g}L\bi…
Blandford-Znajek Process in Einsteinian Cubic Gravity
Jun Peng, Xing-Hui Feng
In this paper, we investigate the Blandford-Znajek (BZ) process within the framework of Einsteinian cubic gravity (ECG). To analytically study the BZ process using the split monopo…
Conserved quantities for asymptotically AdS spacetimes in quadratic curvature gravity in terms of a rank-4 tensor
Jun-Jin Peng, Yao Wang, Wei-Jie Guo
We investigate the conserved quantities associated to Killing isometries for asymptotically AdS spacetimes within the framework of quadratic-curvature gravity. By constructing a ra…
Manifolds of Lie-Group-Valued Cocycles and Discrete Cohomology
Alexandru Chirvasitu, Jun Peng
Consider a compact group acting on a real or complex Banach Lie group , by automorphisms in the relevant category, and leaving a central subgroup invariant. We defi…
An anisotropic bouncing universe in non-local gravity
K. Sravan Kumar, Shubham Maheshwari, Anupam Mazumdar +1
We show that it is possible to realize a cosmological bouncing solution in an anisotropic but homogeneous Bianchi-I background in a class of non-local, infinite derivative theories…
Observational Signature and Additional Photon Rings of Asymmetric Thin-shell Wormhole
Jun Peng, Minyong Guo, Xing-Hui Feng
Recently, a distinct shadow mechanism was proposed by Wang et al. from the asymmetric thin-shell wormhole (ATW) in [Phys. Lett. B 811 (2020) 135930]. On the other hand, Gralla et a…
