Title: Domain Wall Dynamics In Id Quantum Antiferromagnets
Author: Villares Ferrer A.
Caldeira A.O.
Abstract: The problem, of dissipative motion of domain walls (DW) in the case of tetramethyl ammonium manganese chloride (TMMC) is studied as a function of the external magnetic field, and the temperature. Two specific situations are analyzed separately; the first, above the transition temperature TN, in which the classical motion of the spin degree of freedom may be described by a sine-Gordon equation of motion and, the second, below TN, in which the system may be described by a double sine-Gordon equation of motion. The existence of a dissipative regime for the DW motion and its influence on the dynamical structure factor - which might be experimentally detected - are investigated. © 2001 Elsevier Science B.V.
