Can hail and rain nucleate cloud droplets?
Prasanth Prabhakaran, Stephan Weiss, Alain Pumir +2
We present results from moist convection in a mixture of pressurized sulfur hexa-flouride (liquid and vapor) and helium (gas) to model the wet and dry components of the earth's atm…
Suppression of spatially periodic patterns by dc voltage
Nándor Éber, Péter Salamon, Balázs András Fekete +3
The effect of superposed dc and ac applied voltages on two types of spatially periodic instabilities in nematic liquid crystals, flexoelectric domains (FD) and electroconvection (E…
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…
An introduction to the Ginzburg-Landau theory of phase transitions and nonequilibrium patterns
P. C. Hohenberg, A. P. Krekhov
This paper presents an introduction to phase transitions and critical phenomena on the one hand, and nonequilibrium patterns on the other, using the Ginzburg-Landau theory as a uni…
Flashing flexodomains and electroconvection rolls in a nematic liquid crystal
Peter Salamon, Nandor Eber, Alexei Krekhov +1
Pattern forming instabilities induced by ultralow frequency sinusoidal voltages were studied in a rod-like nematic liquid crystal by microscopic observations and simultaneous elect…
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…
