Dynamic structure factors of a Heisenberg model ferrofluid
Using the results of our previous papers [Physica A 220 (1995) 325; Physica A 234 (1996) 129], where the generalized transport equations for a Heisenberg-like model of a ferrofluid were derived and the hydrodynamic collective mode spectrum has been studied, in this work we consider the expressions...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | Using the results of our previous papers [Physica A 220 (1995) 325; Physica A 234 (1996) 129], where the generalized transport equations for a
Heisenberg-like model of a ferrofluid were derived and the hydrodynamic
collective mode spectrum has been studied, in this work we consider the
expressions for hydrodynamic time correlation functions in the limit of small
wavenumbers k and frequencies ω . The analytical results for the time
correlation functions of `particle density–particle density' and `spin density–
spin density', being exact in the hydrodynamic limit, are obtained. The expressions for the corresponding dynamical structure factors are analyzed. |
