Transverse acoustic wave in molecular magnets via electromagnetically induced transparency

Abstract

We have studied the propagation properties of transverse acoustic wave in molecular magnets in the presence of a strong ac magnetic field. Due to quantum interference introduced by the strong electromagnetic field, the acoustic wave can propagate without absorption under appropriate conditions, which is a direct result of electromagnetically induced transparency effect. Meanwhile, the nonlinear effects should be considered in the propagation of the acoustic wave because electromagnetic induction transparency effect can greatly enhance nonlinear effects. The transverse acoustic wave propagation equation including nonlinear effects in molecular magnets has been investigated and the corresponding accurate analytic solutions have been obtained. We believe that our research may promote the understanding of the acoustic wave's properties in molecular magnets.
