A New Approach to Black Hole Thermodynamics in General EMD-like Theories
Peng-Yu Wu, H. Lu
We consider general EMD-like theories involving arbitrary numbers of both Maxwell fields and dilatonic scalars. We study charged black holes and derive several algebraic and differ…
Black p-brane Thermodynamics without Constructing Solutions
Bing-Yang Han, H. Lu
This paper generalizes the method used in the previous article 2512.09930 to black -brane thermodynamics in arbitrary dimensions containing black holes and strings as special ca…
Classification of Oppenheimer-Snyder Collapse: Singular, Bouncing, and Soft-Landing Scenarios
Zhi-Chao Li, H. Khodabakhshi, H. Lu
We study Oppenheimer-Snyder (OS) gravitational collapse matched to a general static, spherically symmetric exterior spacetime. Unlike the Schwarzschild case, two new features can a…
The Upper Bound of Event Horizon Formation Time in Generalized Oppenheimer-Snyder Collapse
Zhi-Chao Li, H. Khodabakhshi, H. Lu
We prove that, in the framework of the Oppenheimer-Snyder collapse, the Schwarzschild exterior maximizes the event horizon formation time among all a…
Gravitational Collapse: Generalizing Oppenheimer-Snyder and a Conjecture on Horizon Formation Time
H. Khodabakhshi, H. Lu, F. Shojai
We generalize the Oppenheimer-Snyder model of gravitational collapse by considering a broader class of static, spherically symmetric exterior spacetimes, with an interior geometry…
Weak Cosmic Censorship Conjecture Cannot be Violated in Gedanken Experiments
Peng-Yu Wu, H. Khodabakhshi, H. Lu
We innovate a systematic investigation of the Weak Cosmic Censorship Conjecture (WCCC) using gedanken experiments involving black hole perturbations by test particles. We classify…
Regular Electric Black Holes from EMS Gravity
Zhi-Chao Li, H. Lu
We construct Einstein-Maxwell-Scalar (EMS) theories that admit regular electric black holes. Such a Maxwell-scalar theory is equivalent to some nonlinear electrodynamics (NLED) at…
Quadratic Curvature Correction and Its Breakdown to Thermodynamics of Rotating Black Holes
Peng-Yu Wu, H. Lu
We adopt the Reall-Santos method to obtain the quadratic curvature corrections to the thermodynamics of Myers-Perry rotating black holes in diverse dimensions. We consider the corr…
Observational Feasibility of 4D Einstein-Gauss-Bonnet Cosmology: Bouncing and Non-Bouncing Universes
H. Khodabakhshi, M. Farhang, H. Lü
This paper analyzes the possibility of bouncing and non-bouncing universes in the framework of four-dimensional Einstein-Gauss-Bonnet (4D-EGB) gravity, corresponding respectively t…
Cosmological Time Crystals from Gauss-Bonnet Gravity in Four Dimensions
H. Khodabakhshi, F. Shojai, H. Lü
We investigate various cosmological aspects of a 4-Dimensional Gauss-Bonnet Lagrangian, which is integrated into the Einstein Lagrangian with an arbitrary sign, using the Friedman-…
On the Lagrangian Holographic Relation at and Limits of Gravity
H. Khodabakhshi, H. Lu, R. B. Mann
The gravitational Lagrangian can be written as a summation of a bulk and a total derivative term. For some theories of gravity such as Einstein gravity, or more general Lovelock gr…
Classical Holographic Relations and Alternative Boundary Conditions for Lovelock Gravity
H. Khodabakhshi, H. Lu
We obtain the classical holographic relation for the general Lovelock gravity and decompose the full Lagrangian into the bulk term and the surface term, expressed as a total deriva…
