Nonsingular black holes and nonsingular universes in the regularized Lovelock gravity

Changjun Gao, Shuang Yu, Jianhui Qiu

It is found that, when the coupling constants in the theory of regularized Lovelock gravity are properly chosen and the number of Lovelock tensors , ther…

When the regularized Lovelock tensors are kinetically coupled to scalar field

Changjun Gao, Shuang Yu, Jianhui Qiu

The recently proposed regularized Lovelock tensors are kinetically coupled to the scalar field. The resulting equation of motion is second order. In particular, it is found that wh…

Constructing black holes in Einstein-Maxwell-scalar theory

Shuang Yu, Jianhui Qiu, Changjun Gao

Exact black hole solutions in the Einstein-Maxwell-scalar theory are constructed. They are the extensions of dilaton black holes in de Sitter or anti de Sitter universe. As a resul…

An exact black hole spacetime with scalar field and its shadow together with quasinormal modes

Shuang Yu, Changjun Gao

We find an exact black hole solution with a minimally coupled scalar field. The corresponding spacetime has two horizons and one of the them is the black hole event horizon and the…

Gravity, matters and dark energy on the minimal surfaces

Changjun Gao, Shuang Yu

We propose gravity, matters and dark energy may be confined on different four dimensional \emph{minimal surfaces} for the observer in five dimensional spacetime. Following this ide…

Exact black hole solutions with non-linear electrodynamic field

Shuang Yu, Changjun Gao

We construct exact black hole solutions to Einstein gravity with nonlinear electrodynamic field. In these solutions, there are in general four parameters. They are physical mass, e…
