Particle dynamics around quintessential Reissner-Nordström black hole

Abstract

In this article, we study the dynamics of neutral as well as charged particle in the presence of magnetic field around Reissner-Nordström black hole surrounded by quintessence by taking into account Noether symmetries and conservation laws in the corresponding spacetime. Using these conservation laws, we explore the effect of angular momentum, quintessence parameter, and magnetic field graphically on the dynamics of neutral/charged particles in the context of the effective potential, effective force, and escape velocity. Additionally, we investigate the orbit stability of the said spacetime with the help of the Lyapunov exponent.
