Smarr Integral Formula of D-dimensional Stationary Spacetimes in Einstein-Æther-Maxwell Theroy
Fei-hung Ho, Shao-Jun Zhang, Hai-Shan Liu +1
Using the Wald formalism, we investigate the thermodynamics of charged black holes in D-dimensional stationary spacetimes with or without rotations in Einstein-æther-Maxwell theory…
The Effects of Running Gravitational Coupling On Rotating Black Holes
Sumarna Haroon, Mubasher Jamil, Kai Lin +3
In this work we investigate the consequences of running gravitational coupling on the properties of rotating black holes. Apart from the changes induced in the space-time structure…
Cosmological dynamics of mimetic gravity
Jibitesh Dutta, Wompherdeiki Khyllep, Emmanuel N. Saridakis +2
We present a detailed investigation of the dynamical behavior of mimetic gravity with a general potential for the mimetic scalar field. Performing a phase-space and stability analy…
Phase Portraits of general f(T) Cosmology
A. Awad, W. El Hanafy, G. G. L. Nashed +1
We use dynamical system methods to explore the general behaviour of cosmology. In contrast to the standard applications of dynamical analysis, we present a way to transform…
Pre-inflationary dynamics in loop quantum cosmology: Power-law potentials
M. Shahalam, Manabendra Sharma, Qiang Wu +1
In this paper, we study the pre-inflationary dynamics for the power-law potential with in the framework of loop quantum cosmology. In the case where the…
Cosmic acceleration sourced by modification of gravity without extra degrees of freedom
Abhineet Agarwal, R. Myrzakulov, S. K. J. Pacif +2
In this paper, we investigate a scenario in which late time cosmic acceleration might arise due to coupling between dark matter and baryonic matter without resorting to dark energy…
