Open AccessOn the late-time tails of massive perturbations in spherically symmetric black holes
It was first pointed out by Koyama and Tomimatsu that, under reasonable assumptions, the asymptotic late-time tails of massive scalar perturbations in the far zone of spherically symmetric black hole spacetime...

Open AccessQuasinormal modes in two-photon autocorrelation and the geometric-optics approximation
In this work, we study the black hole light echoes in terms of the two-photon autocorrelation and explore their connection with the quasinormal modes. It is shown that the above time-domain phenomenon can be a...

Open AccessCuspy and fractured black hole shadows in a toy model with axisymmetry
Cuspy shadow was first reported for hairy rotating black holes, whose metrics deviate significantly from the Kerr one. The non-smooth edge of the shadow is attributed to a transition between different branches...

Open AccessOn quasinormal frequencies of black hole perturbations with an external source
In the study of perturbations around black hole configurations, whether an external source can influence the perturbation behavior is an interesting topic to investigate. When the source acts as an initial pul...

A new rotating black hole in quintessential dark energy and its thermodynamics
The spacetime metric for a rotating black hole in a quintessential field can take various forms owing to the ambiguity of the state equation for quintessential dark energy in rotating spacetime. Herein, to pro...

Entropy of Vaidya Black Hole on Apparent Horizon with Minimal Length Revisited
By considering the generalized uncertainty principle, the degrees of freedom near the apparent horizon of Vaidya black hole are calculated with the thin film model. The result shows that a cut-off can be intro...

Stability of curvature perturbation with new covariant form for energy-momentum transfer in dark sector
It was found that the model with interaction between cold dark matter (CDM) and dark energy (DE) proportional to the energy density of CDM ρ m and const...

Another two dark energy models motivated from Károlyházy uncertainty relation
The Károlyházy uncertainty relation indicates that there exists a minimal detectable cell δt 3 over the region t 3 in Minkowski space-time. Due to the energy-time uncertainty relat...

Lax connections and solutions of the hybrid superstring on AdS 2 × S 2
In this paper, we show that the Lax connections can yield new classical solutions with a spectral parameter of the hybrid formulism for the Type IIB superstring in an AdS 2 × S ...

Construction of the elliptic gaudin system based on Lie algebra
Gaudin model is a very important integrable model in both quantum field theory and condensed matter physics. The integrability of Gaudin models is related to classical r-matrices of simple Lie algebras and semi-s...

Relativistic hadronic cascade analysis of two-pion Bose-Einstein correlation for Si + Au collisions at AGS energy
The proposed relativistic hadronic cascade model has been used to analyse two-pion Bose-Einstein correlation in central collision of Si + Au at AGS energy. Theπ − π
