Quasinormal Modes of Massless Scalar Field Perturbation in Reissner-Nordström-de Sitter Quintessence Spacetime

Abstract

Using the WKB approximation method, the massless scalar quasinormal modes are studied in Reissner-Nordström-de Sitter quintessence spacetime. We analyze the effective potential and QNMs frequencies by varying angular harmonic index l, mass M, charge Q, quintessence energy b and cosmological constant L 2 . The results show the effective potential and QNMs frequency are related to l, M, Q, b and L 2 . Moreover, the b and L 2 can make the effective potential and QNMs frequency reduces.
