Abstract

We investigate the Einstein-Maxwell-scalar theory with a quasi-topological term. Considering exponential couplings to Maxwell term, quasi-topological term, and both terms, we obtain three sets of infinite scalarized charged black holes by taking into account tachyonic instability of dyonic Reissner-Nordstr\"{o}m black hole. Each set of infinite scalarized charged black holes is classified by the number of n=0,1,2,n=0,1,2,\cdots, where n=0n=0 is called the fundamental black hole and n=1,2,n=1,2,\cdots denote the nn-excited black holes. All n=0n=0 black holes are stable against the radial perturbation, while all n=1,2n=1,2 black holes are unstable.
