Surface alignment disorder and pseudo-Casimir forces in smectic-A liquid crystalline films
Fahimeh Karimi Pour Haddadan, Ali Naji, Rudolf Podgornik
Random (disordered) components in the surface anchoring of the smectic-A liquid crystalline film in general modify the thermal pseudo-Casimir interaction. Anchoring disorder of the…

Pseudo-Casimir interactions and surface anchoring duality in bookshelf geometry of smectic-A liquid crystals
Fahimeh Karimi Pour Haddadan, Ali Naji, Rudolf Podgornik
We analyze the transverse intersubstrate pseudo-Casimir force, arising as a result of thermal fluctuations of the liquid crystalline layers of a smectic-A film confined between two…

Liquid-crystalline Casimir effect in the presence of a patterned substrate
F. Karimi Pour Haddadan, F. Schlesener, S. Dietrich
We consider a nematic liquid crystal confined by two parallel planar interfaces, one being laterally homogeneous and the other provided by a substrate endowed with a periodic chemi…
