Exceptional Points in Quasinormal Spectra of Hairy Black Holes
Lang Cheng, Xiaobo Guo, Yuhan Li +2
Exceptional points (EPs) in quasinormal mode (QNM) spectra are non-Hermitian degeneracies at which both the eigenvalues and eigenfunctions coalesce. In this paper, we identify an E…
Lyapunov exponents and phase transition of charged Ads black hole in quintessence
Xiaobo Guo, Rui Yang, Yizhi Liang +1
This study investigates the phase transitions of RN-AdS black holes immersed in a quintessence field, employing Lyapunov exponents as a dynamical probe to characterize the thermody…
Probing Phase Structure of Black Holes with Lyapunov Exponents
Xiaobo Guo, Yuhang Lu, Benrong Mu +1
We conjecture that there exists a relationship between Lyapunov exponents and black hole phase transitions. To support our conjecture, Lyapunov exponents of the motion of particles…
Thermodynamics with pressure and volume of black holes based on two assumptions under scalar field scattering
Benrong Mu, Jing Liang, Xiaobo Guo
Recently, a new assumption was proposed in [Phys. Rev. D 100, no.10, 104022 (2019)]. This assumption considers that the energy of the particle changes the enthalpy of the black hol…
Thermodynamics with pressure and volume of 4D Gauss-Bonnet AdS Black Holes under the scalar field
Benrong Mu, Jing Liang, Xiaobo Guo
By using the scattering of a scalar field, we discuss the thermodynamics and overcharging problem in a 4D Gauss-Bonnet AdS black hole in both the normal phase space and extended ph…
Remarks on the weak cosmic censorship conjecture of RN-AdS black holes with cloud of strings and quintessence under the scalar field
Jing Liang, Xiaobo Guo, Deyou Chen +1
In this paper, we investigate the thermodynamics and weak cosmic censorship conjecture in a RN-AdS black hole with the cloud of strings and quintessence by the scattering of a scal…
Chaotic Motion around a Black Hole under Minimal Length Effects
Xiaobo Guo, Kangkai Liang, Benrong Mu +2
We use the Melnikov method to identify chaotic behavior in geodesic motion perturbed by the minimal length effects around a Schwarzschild black hole. Unlike the integrable unpertur…
Quantum Tunneling In Deformed Quantum Mechanics with Minimal Length
Xiaobo Guo, Bochen Lv, Jun Tao +1
In the deformed quantum mechanics with a minimal length, one WKB connection formula through a turning point is derived. We then use it to calculate tunnelling rates through potenti…
The Classical Limit of Minimal Length Uncertainty Relation:Revisit with the Hamilton-Jacobi Method
Xiaobo Guo, Peng Wang, Haitang Yang
The existence of a minimum measurable length could deform not only the standard quantum mechanics but also classical physics. The effects of the minimal length on classical orbits…
