Understanding Gravitational Entropy of Black Holes: A New Proposal via Curvature Invariants
Daniele Gregoris, Yen Chin Ong
Partly motivated by the arrow of time problem in cosmology and the Weyl curvature hypothesis formulated by Roger Penrose, previous works in the literature have proposed - among oth…
Landauer's principle in Qubit-Cavity quantum field theory Interaction in Vacuum and Thermal States
Hao Xu, Yen Chin Ong, Man-Hong Yung
Landauer's principle has seen a boom of interest in the last few years due to the growing interest in quantum information sciences. However, its relevance and validity in the conte…
The Hookean Law of Black Holes and Fragmentation: Insights from Maximum Force Conjecture and Ruppeiner Geometry
Sofia Di Gennaro, Michael R. R. Good, Yen Chin Ong
We show that the notion of "Hookean law" , suitably defined in asymptotically flat singly spinning Myers-Perry black hole spacetimes in dimensions , is related…
Traversable Wormhole in Einstein 3-Form Theory With Self-Interacting Potential
Mariam Bouhmadi-López, Che-Yu Chen, Xiao Yan Chew +2
We numerically construct a symmetric wormhole solution in pure Einstein gravity supported by a massive -form field with a potential that contains a quartic self-interaction term…
On the Counter-Rotation of Closed Timelike Curves
Yuanyuan Duan, Fangxun Liu, Yu Wang +1
While it is tempting to think of closed timelike curves (CTCs) around rotating bodies such as a black hole as being "caused" by the rotation of the source, Andréka et al. pointed o…
How Anti-de Sitter Black Holes Reach Thermal Equilibrium
Ru Ling, Hao Xu, Yen Chin Ong
It is commonly known in the literature that large black holes in anti-de Sitter spacetimes (with reflective boundary condition) are in thermal equilibrium with their Hawking radiat…
A Critical Assessment of Black Hole Solutions With a Linear Term in Their Redshift Function
Daniele Gregoris, Yen Chin Ong, Bin Wang
Different theories of gravity can admit the same black hole solution, but the parameters usually have different physical interpretations. In this work we study in depth the linear…
Feasibility of Primordial Black Hole Remnants as Dark Matter in View of Hawking Radiation Recoil
Sofia Di Gennaro, Yen Chin Ong
It has recently been suggested that black hole remnants of primordial origin are not a viable dark matter candidate since they would have far too large a velocity due to the recoil…
How Not to Extract Information From Black Holes: Cosmic Censorship as a Guiding Principle
Sofia Di Gennaro, Yen Chin Ong
Black holes in general relativity are commonly believed to evolve towards a Schwarzschild state as they gradually lose angular momentum and electrical charge under Hawking evaporat…
