Quasinormal modes and thermodynamic properties of GUP-corrected Schwarzschild black hole surrounded by quintessence

Understand

We study the Quasinormal Modes (QNMs) of the Schwarzschild black hole surrounded by a quintessence field after implementing the quantum corrections to its solution as required by the Generalised Uncertainty Principle (GUP).

• We analyse the dependence of the QNMs on the deformation parameters of GUP as well as on the quintessence parameter.
• In most cases the QNMs show the appreciable dependency on these parameters.
• For a better idea of the accuracy of calculations of QNMs, we compare the results of the QNMs obtained via Mashhoon method with the 6th order WKB method.
