Effect of global monopole on the microscopic structure of rn-ads black hole

Abstract

In this work we study the microscopic structure of RN-AdS Black hole with a monopole. We utilize the connection between the thermodynamic Ruppeiner geometry and the nature of underlying microscopic interaction. The behaviour of the Ruppeiner invariant scalar is analysed in the extended space. The sign of the curvature scalar is the measure of the strength of attractive or repulsive statistical interaction. It is observed that the monopole parameter influences the microscopic structure of the black hole. © Springer Nature Singapore Pte Ltd 2020.
