In this work, we use exact matrix diagonalization to explore the many-body
localization (MBL) transitions in quantum Ising chains with disordered
nearest-neighbour couplings, disordered next-nearest-neighbour couplings and
disordered external fields. It is demonstrated that the fidelity can be used to
characterize the interaction-driven MBL transition in this closed spin system in
a manner that is consistent with previous analytical and numerical results. We
compute the fidelity for high-energy many-body eigenstates, namely, the
excited-state fidelity. It is demonstrated that disordered nearest-neighbour
couplings, disordered next-nearest-neighbour couplings and disordered external
fields each have different effects on the MBL transition. Furthermore, we
investigate the MBL transition of a quantum Ising chain with both disordered
nearest-neighbour couplings and disordered next-nearest-neighbour couplings to
see how these two types of disordered couplings drive the occurrence of the MBL
transition.
