A black hole is superentropic if it violates the reverse isoperimetric inequality. Recently, some studies have indicated that some four dimensional superentropic black holes have the null hypersurface caustics (NHC) outside their event horizons. In this paper, we extend to explore whether or not the NHC exists in the cases of high dimensional superentropic black holes. We consider the singly rotating Kerr-AdS superentropic black holes in arbitrary dimensions and the singly rotating charged…

Classifying topology of consistent thermodynamics of four-dimensional Lorentzian NUT-charged spacetimes

In this paper, employing the uniform modified form of the generalized off-shell Helmholtz free energy, we investigate the topological numbers for the whole class of four-dimensional NUT-charged

Light deflection angle by superentropic black holes

Motivated by recent works on light deflection and shadow behaviors on AdS geometries [S. Haroon, M. Jamil, K. Jusufi, K. Lin and R. B. Mann, Phys. Rev. D 99 (2019) 044015, arXiv:1810.04103; A.

Shadowless rapidly rotating yet not ultraspinning Kerr- AdS4 and Kerr-Newman- AdS4 black holes

We find that the Kerr-(Newman)-AdS4 black hole will be shadowless if its rotation parameter is larger than a critical value and the shadowless-ness may be related to the appearance of the null

Black hole enthalpy and an entropy inequality for the thermodynamic volume

In a theory where the cosmological constant $\Lambda$ or the gauge coupling constant $g$ arises as the vacuum expectation value, its variation should be included in the first law of thermodynamics

Null hypersurface caustics, closed null curves, and super entropy

Recently it was discovered that null hypersurfaces can develop caustics outside the event horizon of super-entropic Kerr-AdS black holes, in contrast to the usual Kerr-AdS case. In this work we

A three-dimensional light-like foliation of a spacetime geometry is one particular way of studying its light cone structure and has important applications in numerical relativity. In this paper, we

A new class of rotating anti-de Sitter black hole solutions with noncompact event horizons of finite area in any dimension is constructed and their thermodynamics are studied to suggest more stringent conditions under which this conjecture may hold.
