Joule-Thomson expansion and quasinormal modes of regular non-minimal magnetic black hole

The Joule-Thomson effect and quasinormal modes (QNM) onto regular non-minimal magnetic charged black hole with a cosmological constant are being investigated. For this purpose, we extract some thermodynamical parameters such as pressure (P) and mass (M) in the presence of magnetic (Q(m)) as well as electric (q) charge. These parameters lead to inversion temperature (T-i), pressure (P-i) and corresponding isenthalpic curves. We introduce the tortoise coordinate and the Klein-Gordon wave equation which leads to the second-order ordinary Schrodinger equation. We find out the complex frequencies of QNMs through the massless scalar field perturbation which satisfy boundary conditions by using the first-order Wentzel-Kramers-Brillouin (WKB) technique.
