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…
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…
Influence of Quantum Correction on the Black Hole Shadows, Photon Rings and Lensing Rings
Jun Peng, Minyong Guo, Xing-Hui Feng
We calculate the photon sphere and critical curve for the quantum corrected Schwarzschild black hole, finding that they violate an universal inequalities proved for…

Xing-Hui Feng, H. Lu
Recently a sequence of inequalities relating the black hole horizon, photon sphere, shadow were proposed for spherically symmetric and static black holes, providing the upper bound…

Jincheng An, Jun Peng, Yan Liu +1
It has been proved that arbitrarily high-energy collision between two particles can occur near the horizon of an extremal Kerr black hole as long as the energy and angular mome…

Xing-Hui Feng, Wei-Jian Geng, H. Lu
We show that in D=2n+1 dimensions, when mass is negative and all angular momenta are non-vanishing, Kerr and Kerr-AdS metrics describe smooth time machines, with no curvature singu…

The recently proposed complexity-action conjecture allows one to calculate how fast one can produce a quantum state from a reference state in terms of the on-shell action of the du…
