Hawking Temperature and the Inverse-Radius Scale of the Horizon

Michael R. R. Good, Yen Chin Ong

The Hawking temperature of a Schwarzschild black hole can be heuristically derived by identifying the temperature with the inverse radius of the horizon up to a multiplicative cons…

Generalized Entropy Implies Varying-G: Horizon Area Dependent Field Equations and Black Hole-Cosmology Coupling

Hengxin Lu, Sofia Di Gennaro, Yen Chin Ong

When the Bekenstein-Hawking entropy is modified, ambiguity often arises concerning whether the Hawking temperature or the thermodynamic mass should be modified. The common practice…

Classical Acceleration Temperature (CAT) in a Box

Ahsan Mujtaba, Maksat Temirkhan, Yen Chin Ong +1

A confined, slow-moving, accelerating electron is shown to emit thermal radiation. Since laboratories face spatial constraints when dealing with rectilinear motion, focusing on a f…

Upper Bound of Barrow Entropy Index from Black Hole Fragmentation

Jiayi Xia, Yen Chin Ong

Both classical and quantum arguments suggest that if Barrow entropy is correct, its index must be energy dependent, which would affect the very early universe. Based on thermod…

A Maximum Force Perspective on Black Hole Thermodynamics, Quantum Pressure, and Near-Extremality

Yen Chin Ong

I re-examined the notion of the thermodynamic force constructed from the first law of black hole thermodynamics. In general relativity, the value of the charge (or angular momentum…

A Critique on Some Aspects of GUP Effective Metric

Yen Chin Ong

The generalized uncertainty principle (GUP) is a gravitational correction of Heisenberg's uncertainty principle, which allows us to probe some features of quantum gravity even with…

Electron as a Tiny Mirror: Radiation From a Worldline With Asymptotic Inertia

Michael R. R. Good, Yen Chin Ong

We present a moving mirror analog of the electron, whose worldline possesses asymptotic constant velocity with corresponding beta Bogolubov coefficients that are consistent with fi…

An Effective Sign Switching Dark Energy: Lotka-Volterra Model of Two Interacting Fluids

Yen Chin Ong

One of the recent attempts to address the Hubble and tensions is to consider the Universe started out not as a de Sitter-like spacetime, but rather anti-de Sitter-like. That…

On Black Hole Thermodynamics, Singularity, and Gravitational Entropy

Yen Chin Ong

Many fundamental issues remain for black hole thermodynamics after almost half a century of its conception. For example, what are the underlying degrees of freedom of a black hole…

Lotka-Volterra Models for Extraterrestrial Self-Replicating Probes

Yifan Chen, Jiayi Ni, Yen Chin Ong

A sufficiently advanced extraterrestrial civilization can send out a swarm of self-replicating probes for space exploration. Given the fast-growing number of such a probe, even if…

Holographic Consistency and the Sign of the Gauss-Bonnet Parameter

Yen Chin Ong

If Einstein-Gauss-Bonnet gravity is obtained as a low energy limit of string theory, then the Gauss-Bonnet parameter is essentially the inverse string tension and thus necessar…

How Barrow Entropy Modifies Gravity: With Comments on Tsallis Entropy

Sofia Di Gennaro, Hao Xu, Yen Chin Ong

Barrow proposed that the area law of the horizon entropy might receive a "fractal correction" due to quantum gravitational effects, with $0\leqslant Δ\leqslant…

Decoherence and Landauer's Principle in Qubit-Cavity Quantum-Field-Theory Interaction

Hao Xu, Si Yu Chen, Yen Chin Ong

We consider quantum decoherence and Landauer's principle in qubit-cavity quantum field theory (QFT) interaction, treating the qubit as the system and cavity QFT as the environment.…

Sign Switching Dark Energy from a Running Barrow Entropy

Sofia Di Gennaro, Yen Chin Ong

Barrow proposed that the area law of the entropy associated with a horizon might receive a "fractal correction" due to quantum gravitational effects -- in place of , we…

On the Chandrasekhar Limit in Generalized Uncertainty Principles

Daniele Gregoris, Yen Chin Ong

The Chandrasekhar limit for white dwarfs has been confirmed by many astrophysical observations. However, how to obtain it theoretically in models which rely on other-than-Heisenber…

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…

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…
