The island rule for the entanglement entropy is applied to an eternal Reissner-Nordstr\"om black hole. key ingredient that hole assumed be in thermal equilibrium with a heat bath of arbitrary temperature and so generalized treated as being off-shell. Taking on-shell condition off-shell entropy, we find then obtain following rule. For non-extremal hole, grows linearly time can saturated after Pa...

We construct non dispersive two soliton solutions to the three dimensional gravitational Hartree equation whose trajectories asymptotically reproduce the nontrapped dynamics of the gravitational two body problem.

In this work, we introduce Fibonacci– Halpern iterative scheme ( FH scheme) in partial ordered Banach space (POB space) for monotone total asymptotically non-expansive mapping (, MTAN mapping) that defined on weakly compact convex subset. We also discuss the results of weak and strong convergence scheme.
 Throughout compactness condition m-th iterate some natural m is necessary to ensure c...

This work investigates the influence of Lorentz symmetry breaking in bending angle massive particles and light for bumblebee black hole solutions. The solutions analyzed break due to a non-zero vacuum expectation value field. We use Ishihara method, which allows us study finite distances, it is applicable non-asymptotically flat spacetimes when considering receiver viewpoint. In order analyze d...

Asymptotically nonlocal field theories represent a sequence of higher-derivative whose limit point is ghost-free, infinite-derivative theory. Here, we extend previous work on pure scalar and Abelian gauge to asymptotically non-Abelian theories. In particular, confirm that there in which the Lee-Wick spectrum can be decoupled, but where hierarchy problem resolved via an emergent scale regulates ...
