On the large interaction asymptotics of the free energy density of the Ising chain with disordered centered external field

This article completes [G. Giacomin, R. Greenblatt, ALEA 2022] by identifying explicitly the leading coefficient in the asymptotic development of the free energy density of the centered Random Field Ising Chain as the spin-spin interaction of the chain goes to infinity, under general assumptions on the disorder law.
