| Abstract | The order parameter dynamics has been measured by photon autocorrelation spectroscopy close to the lambda-line of a ferroealectric liquid crystal in a transverse magnetic field. It is shown that the critical dynamics can be observerd and analysed in the vicinity of the Lifshitz point in this system. Preliminary results indicate the existence of a nearly gapless phason mode for small magnetic fields, whereas above 10 T phason excitations exhibit a finite frequency gap. | |
