“…As the next step, we fix all the free parameters, namely, the multipole number l, the BH mass M , the polymeric function P , and the minimum area gap of LQG A 0 . Finally, we use the quantization condition (33) and a root finder to calculate the QN modes.…”

“…The QNMs of BH solutions undergoing scalar perturbations have been investigated in higher dimensional Einstein-Yang-Mills theory [27], Einstein-Born-Infeld gravity [28], dRGT massive gravity [29], and conformal Weyl gravity [15]. In addition, the QN modes of Schwarzschild BHs with Robin boundary conditions [30], the dirty BHs [31], the Kaluza-Klein BHs [32], and charged BHs with Weyl corrections [33] have been studied.…”

We study the evolution of a test scalar field on the background geometry of a regular loop quantum black hole (LQBH) characterized by two loop quantum gravity (LQG) correction parameters, namely, the polymeric function and the minimum area gap. The calculations of quasinormal frequencies in asymptotically flat spacetime are performed with the help of higher-order WKB expansion and related Padé approximants, the improved asymptotic iteration method (AIM), and time-domain integration. The effects of free parameters of the theory on the quasinormal modes are studied and deviations from those of the Schwarzschild BHs are investigated. We show that the LQG correction parameters have opposite effects on the quasinormal frequencies and the LQBHs are dynamically stable.

“…Another important avenue for future work is to include thermal fluctuations, as it is known that fluctuations give additional contributions and modify the points where the Ruppeiner scalar R goes to zero. The effect of statistical fluctuations on thermodynamics and phase transitions is well studied and is known to change the definitions of entropy and free energy, with particularly novel consequences for large black holes [37,[89][90][91][92][93][94]. Thus, it should be intriguing to consider additional effects due to thermal fluctuations on the thermodynamic geometry of black holes with quintessence studied in this work.…”

In this paper, we study the effect of dark energy on the extended thermodynamic structure and interacting microstructures of black holes in AdS, through an analysis of thermodynamic geometry. Considering various limiting cases of the novel equation of state obtained in charged rotating black holes with quintessence, and taking enthalpy H as the key potential in the extended phase space, we scrutinize the behavior of the Ruppeiner curvature scalar R in the entropy-pressure (S,P)-plane (or equivalently in the temperature-volume (T,V)-plane). Analysis of R empirically reveals that dark energy parameterized by α, significantly alters the dominant interactions of neutral, charged and slowly rotating black hole microstructures. In the Schwarzschild-AdS case: black holes smaller than a certain size continue to have attractive interactions whereas larger black holes are completely dominated by repulsive interactions which arise to due dark energy. For charged or rotating AdS black holes with quintessence, R can change sign at multiple points depending upon the relation between α and charge q or angular momentum J. In particular, above a threshold value of α, R is never negative at all, suggesting heuristically that the repulsive interactions due to quintessence are long ranged as opposed to the previously known short ranged repulsion in charged AdS black holes. A mean field interaction potential is proposed whose extrema effectively capture the points where the curvature R changes sign.

“…By using the tunneling approach under the influence of quantum gravity the Hawking temperture for different types of BH have been discussed [40]- [44]. Sharif and Zunaira [45,46] have computed the thermodynamics, quasi-normal modeand thermal fluctuations of charged BHs with the help of Weyl corrections. The authors found that the system is unstable for the small radii of BHs under the influence of first order corrections and by using the heat capacity and Hessian matrix technique, they have also studied the stable conditions of the system.…”

In this paper, we compute the Hawking temperature by applying quantum tunneling approach for the Horndeski like black holes. We utilize the semi-classical phenomenon and WKB approximation to the Lagrangian field equation involving generalized uncertainty principle (GUP) and compute the tunneling rate as well as Hawking temperature. For the zero gravity parameter, we obtain results consistent without correction parameter or original tunneling. Moreover, we study the thermal fluctuations of the considered geometry and examine the stable state of the system by heat capacity technique. We also investigate the behaviour of thermodynamic quantities under the influence of thermal fluctuations. We observe from the graphical analysis, the corresponding system is thermodynamically stable with these correction terms.
