Patterns in Directional Solidification

1990
There have recently been a set of new phenomena observed in the directional solidification of liquid crystals, including travelling waves and spatial period doubling. We apply the integro-differential method to the liquid crystal system of Simon et.al. and show that we can reproduce the period doubling state.

Pattern selection in directional solidification

Physical Review B, 1983
The equations of motion for a slightly deformed planar solidification front advancing with a steady velocity and stabilized by a thermal gradient are integrated numerically. The regime where the interface develops a cellular pattern is analyzed. We study the case where the system is subjected to Gaussian white noise.

Asymptotic dynamics in directional solidification

2008
We study a strongly nonlinear equation describing the long-wave asymptotic behaviour of rapid directional solidification with weak convective coupling. Taking into account kinetic and disequilibrium effects in the basic equation, we are able to identify various nontrivial integrable subproblems that are absent in previous equations derived for this ...

Erratum: Crystal Anisotropy Directs Solidification

Science, 1984
In the credit for the photograph on page 1086 of the issue of 8 June accompanying the Research News article "Crystal anisotropy directs solidification" by Arthur L. Robinson (p. 1085), Kurt Nassau's affiliation is incorrectly given as Western Electric. Nassau is at AT&T Bell Laboratories, Murray Hill, New Jersey.

Cellular Instabilities in Directional Solidification

1988
The March 1987 Les Houches workshop on “Propagation in Systems far from Equilibrium” allowed us to compare the state of research in a number of different fields where instabilities occur. It appeared clearly that the field of solidification has been much less systematically explored than those, for example, of Rayleigh-Benard instabilities or ...
