Nematic distortions in adjustable geometries: repartitioning and instabilities

Critical damping of first and second sound at a smectic A-nematic phase

The dependence of the threshold values of the electric field and the spatial wavenumber of the distortion on the orienting magnetic field is described.. Also

Critical behaviour of second sound near the smectic A nematic phase transition.. L. Ricard,

on elastic interaction, recalling that its average energy is proportional to 1 /r per unit length of straight and parallel edge dislocations. Simple considerations

In ordinary light, the index is independent of the director field, so usually weaker effects are obtained as compared with extraordinary light. For this reason~ the ordinary light

— It is shown that the magnetic excitations of a system having two singlet levels give rise to velocity shifts of longitudinal phonons in both the ordered and paramagnetic phase of

50.2 °C, fulfills this condition With th~s m~xture, we have indeed observed that the disdmat~on line pinned to the meniscus is planar (see Sect 4) and consequently does not break

- In a nematic phase and, in particular, near a N -+ S, transition, the determination of the y1 twist viscosity coefficient in order to analyse the conditions
