Open AccessPage curves for accelerating black holes
The island paradigm for the fine-grained entropy of Hawking radiation is applied to eternal charged accelerating black holes. In the absence of the island, the entanglement entropy grows linearly and divergent...

Open AccessPage curve and phase transition in deformed Jackiw–Teitelboim gravity
We consider the entanglement island in a deformed Jackiw–Teitelboim black hole in the presence of the phase transition. This black hole has the van der Waals–Maxwell-like phase structure as it is coupled with ...

Open AccessLight-cone sum rule analysis of semileptonic decays \(\varLambda _b^0 \rightarrow \varLambda _c^+ \ell ^- {\overline{\nu }}_\ell \)
In this work, we analyze the semileptonic decay processes of \(\varLambda _b \rightarrow \varLambda _c\) ...

Open AccessCosmological time crystals from Einstein-cubic gravities
By including appropriate Riemann-cubic invariants, we find that the dynamics of classical time crystals can be straightforwardly realized in Einstein gravity on the FLRW metric. The time reflection symmetry is...

Open AccessOn the size of rotating black holes
Recently a sequence of inequalities relating the black hole horizon, photon sphere, shadow were proposed for spherically symmetric and static black holes, providing the upper bound for given mass. In this pape...

Open AccessCanonical interpretation of Y(10750) and \(\Upsilon (10860)\) in the \(\Upsilon \) family
Inspired by the new resonance Y(10750), we calculate the masses and two-body OZI-allowed strong decays of the higher vector bottomonium sates within both screened and linear potential models. We discuss the possi...

Open AccessStrong decay of \(\Lambda _c(2940)\) as a 2P state in the \(\Lambda _c\) family
Considering the mass, parity and \(D^0 p\) ...

Open AccessHorndeski gravity and the violation of reverse isoperimetric inequality
We consider Einstein–Horndeski–Maxwell gravity, together with a cosmological constant and multiple Horndeski axions. We construct charged AdS planar black holes in general dimensions where the Horndeski axions...

Open AccessGödel universe from string theory
The Gödel universe is a direct product of a line and a three-dimensional spacetime we call G \(_\alpha \) ...

Open AccessHigher-derivative gravity with non-minimally coupled Maxwell field
We construct higher-derivative gravities with a non-minimally coupled Maxwell field. The Lagrangian consists of polynomial invariants built from the Riemann tensor and the Maxwell field strength in such a way ...
