Spatiotemporal complexity of electroconvection patterns in nematic liquid crystals
Alexei Krekhov, Bernd Dressel, Werner Pesch +2
We investigate a number of complex patterns driven by the electro-convection instability in a planarly aligned layer of a nematic liquid crystal. They are traced back to various se…
Spatio-temporal Patterns in Inclined Layer Convection
Priya Subramanian, Oliver Brausch, Karen E. Daniels +3
This paper reports on a theoretical analysis of the rich variety of spatio-temporal patterns observed recently in inclined layer convection at medium Prandtl number when varying th…
Patterns driven by combined AC and DC electric fields in nematic liquid crystals
Alexei Krekhov, Werner Decker, Werner Pesch +4
The effect of superimposed ac and dc electric fields on the formation of electroconvection and flexoelectric patterns in nematic liquid crystals was studied. For selected ac freque…
Optical analysis of spatially periodic patterns in nematic liquid crystals: diffraction and shadowgraphy
Werner Pesch, Alexei Krekhov
Optical methods are most convenient to analyze spatially periodic patterns with wavevector in a thin layer of a nematic liquid crystal. In the standard experimental setup a…
Flexoelectricity and pattern formation in nematic liquid crystals
Alexei Krekhov, Werner Pesch, Agnes Buka
We present in this paper a detailed analysis of the flexoelectric instability of a planar nematic layer in the presence of an alternating electric field (frequency ), which lead…
Competition and bistability of ordered undulations and undulation chaos in inclined layer convection
Karen E. Daniels, Oliver Brausch, Werner Pesch +1
Experimental and theoretical investigations of undulation patterns in high-pressure, inclined layer gas convection at a Prandtl number near unity are reported. Particular focus is…
