Abstract
Spontaneous dimerization is found in the S=12 isotropic Heisenberg antiferromagnetic chain with competing nearest- and next-nearest-neighbor exchange, J2J116, and results from the same umklapp processes that lead to the Néel state when easy-axis exchange anisotropy is present. Spontaneous and externally induced dimerizations are contrasted.
