The critical behaviors of the entropy correlation effects in the one dimensional J<Subscript>1</Subscript>-J<Subscript>2</Subscript> Heisenberg model are studied. It is shown that the mutual information or the correlation entropy captures the key features of information about critical fluctuations and can be used to quantify the quantum and...</subscript></subscript>
