Abstract
We study the dynamical spin correlation function of the S = 1/2 antife rromagnetic chain with alternating nearest-neighbor exchange interacti ons and with competing next-nearest-neighbor exchange interactions, em phasizing the role played by the dimer order in the ground state. In p articular, a triplet dimer in the singlet-dimer background is discusse d in connection with the numerical result. (C) 1998 Elsevier Science B .V. All rights reserved.
