Static and dynamic behaviour of walls in nematics above a Freedericks transition
L Leger - Solid State Communications, 1972 - Elsevier
At the Freedericks transition of a nematic slab the molecules can rotate in two different ways,
giving rise to adjacent domains separated by a wall. We present optical observations on the …

Magnetohydrodynamic instabilities in nematic liquid crystals
FM Leslie - Molecular Crystals and Liquid Crystals, 1976 - Taylor & Francis
This paper discusses two problems in which surface alignment, shear flow and a magnetic
field normal to the plane of shear compete to produce instabilities in a nematic. The first is …
