Einstein-scalar field solutions in AdS spacetime: clouds, boundary conditions, and scalar multipoles
Dumitru Astefanesei, Hyat Huang, Jutta Kunz +1
We consider an Einstein-scalar field model which is a consistent truncation of gauged supergravity, the scalar field possessing a potential which is unbounded fr…
Echoes from Classical Black Holes
Hyat Huang, Min-Yan Ou, Meng-Yun Lai +1
We study echoes of free massless scalar from dyonic black holes in Einstein-Maxwell gravity extended with the quasi-topological electromagnetic term. These asymptotically-flat blac…
Static and Dynamic Charged Black Holes
Hyat Huang, Zhong-Ying Fan, H. Lü
We consider a class of Einstein-Maxwell-dilaton theories in general dimensions and construct both static and dynamic charged black holes. We adopt the reverse engineering procedure…
Cosmological Time Crystals From Einstein-Cubic Gravities
Xing-Hui Feng, Hyat Huang, Shou-Long Li +2
By including appropriate Riemman cubic invariants, we find that the dynamics of classical time crystals can be straightforwardly realized in Einstein gravity on the FLRW metric. Th…
Bounce Universe and Black Holes from Critical Einsteinian Cubic Gravity
Xing-Hui Feng, Hyat Huang, Zhan-Feng Mai +1
We show that there exists a critical point for the coupling constants in Einsteinian cubic gravity where the linearized equations on the maximally-symmetric vacuum vanish identical…
Holographic Complexity and Two Identities of Action Growth
Hyat Huang, Xing-Hui Feng, H. Lu
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…
