Hawking radiation of a multi-fractional Schwarzschild black hole
Peng Huang, Fang-Fang Yuan
Following the initial work of Calcagni et al. on the black holes in multi-fractional theories, we focus on the Schwarzschild black hole in multi-fractional theory with q-derivative…
Emergent cosmic space in Rastall theory
Fang-Fang Yuan, Peng Huang
Padmanabhan's emergent cosmic space proposal is employed to study the Rastall theory which involves modifying the conservation law of energy-momentum tensor. As a necessary element…
Uniformly expanding vacuum: a possible interpretation of the dark energy
Peng Huang, Fang-Fang Yuan
Following the spirit of the equivalence principle, we take a step further to recognize the free fall of the observer as a method to eliminate causes that would lead the perceived v…
Disformal transformation in Newton-Cartan geometry
Peng Huang, Fang-Fang Yuan
Newton-Cartan geometry has played a central role in recent discussions of non-relativistic holography and condensed matter systems. Although the conformal transformation in non-rel…
Induced geometry from disformal transformation
Fang-Fang Yuan, Peng Huang
In this note, we use the disformal transformation to induce a geometry from the manifold which is originally Riemannian. The new geometry obtained here can be considered as a gener…
Generalized Hodge dual for torsion in teleparallel gravity
Peng Huang, Fang-Fang Yuan
For teleparallel gravity in four dimensions, Lucas and Pereira have shown that a generalized Hodge dual for torsion tensor can be defined with coefficients determined by mathematic…
Thermodynamic approach to field equations in Lovelock gravity and f(R) gravity revisited
Yan-Gang Miao, Fang-Fang Yuan, Zheng-Zheng Zhang
The first law of thermodynamics at black hole horizons is known to be obtainable from the gravitational field equations. A recent study claims that the contributions at inner horiz…
gravity from holographic Ricci dark energy model with new boundary conditions
Peng Huang, Yong-Chang Huang, Fang-Fang Yuan
Commonly used boundary conditions in reconstructing gravity from holographic Ricci dark energy model (RDE) are found to cause some problem, we therefore propose new boundary…
Entropic corrections and modified Friedmann equations in the emergence of cosmic space
Fang-Fang Yuan, Yong-Chang Huang
In the emergent cosmic space scenario recently proposed by Padmanabhan, the expansion of the universe is attributed to the difference between the number of degrees of freedom on a…
Harrison metrics for the Schwarzschild black hole
Fang-Fang Yuan, Yong-Chang Huang
Based on the hidden conformal symmetry, some authors have proposed a Harrison metric for the Schwarzschild black hole. We give a procedure which can generate a family of Harrison m…
A modified variational principle for gravity in modified Weyl geometry
Fang-Fang Yuan, Yong-Chang Huang
The usual interpretation of Weyl geometry is modified in two senses. First, both the additive Weyl connection and its variation are treated as (1, 2) tensors under the action of We…
Thermodynamics of nonspherical black holes from Liouville theory
Fang-Fang Yuan, Yong-Chang Huang
A Liouville formalism was proposed many years ago to account for the black hole entropy. It was recently updated to connect thermodynamics of general black holes, in particular the…
Hidden conformal symmetry of extremal Kaluza-Klein black hole in four dimensions
Yong-Chang Huang, Fang-Fang Yuan
We study the hidden conformal symmetry of four-dimensional extremal Kaluza-Klein black hole. The scalar Laplacian corresponding to the radial equation in the near-region is rewritt…
