Quasilocal inequalities for attractive gravity probe surface
Tetsuya Shiromizu, Keisuke Izumi, Hirotaka Yoshino +1
We discuss the local and quasilocal properties of the loosely trapped surface (LTS) and the attractive gravity probe surface (AGPS), which have been proposed to characterize the st…
Loosely trapped surface for slowly rotating black hole
Keisuke Izumi, Tetsuya Shiromizu, Daisuke Yoshida +2
We construct the marginal loosely trapped surface (marginal LTS) for the Kerr spacetime with a small Kerr parameter perturbatively, where the LTS condition is saturated. An LTS is…
Attractive gravity probe surface in Einstein-Maxwell system
Kangjae Lee, Keisuke Izumi, Tetsuya Shiromizu +2
We derive areal inequalities for five types of attractive gravity probe surfaces, which were proposed by us in order to characterize the strength of gravity in different ways inclu…
Generalisation of Conformal-Disformal Transformations of the Metric in Scalar-Tensor Theories
Eugeny Babichev, Keisuke Izumi, Karim Noui +2
We study new classes of metric transformations in the context of scalar-tensor theories, which involve both higher derivatives of the scalar field and derivatives of the metric its…
Gedanken Experiments to Destroy a Black Hole by a Test Particle: Multiply Charged Black Hole with Higher Derivative Corrections
Keisuke Izumi, Toshifumi Noumi, Daisuke Yoshida
We investigate a gedanken experiment to destroy an extremally charged black hole by dropping a test particle, provided that there are multiple gauge fields coupled with each…
Attractive gravity probe surface, positivity of quasi-local mass and Arnowitt-Deser-Misner mass expression
Tetsuya Shiromizu, Keisuke Izumi
Under certain conditions, it is shown that the positivity of the Geroch/Hawking quasi-local mass holds for the attractive gravity probe surfaces in any higher dimensions than three…
